Without a careful assessment of the system, clamps and couplings can be subjected to pressures beyond their rating which can cause problems. 0000001636 00000 n Double-check the manufacturers data before choosing a specific flexible hose. 0000036268 00000 n hoses hose end fittings pressure length air bend Quick Exhaust Valves, Check Valves, Flow Controls. For this reason, companies have now begun to color-coordinate their couplers and plugs, with the most common being: Visit our Air Hose Fittings Types Guide To Air Compressor Coupler Types for more information on these. closest value). (NPT - National Pipe Thread), not the actual size. 0000010519 00000 n trailer Its pretty much down to personal preference on the style you choose, though automotive and industrial designs are far more common and easy to find in most hardware stores. For instance, when you plan on using a hose mostly outside or in a cold room, choose a material designed to stay flexible. delivers 3 times more flow than a I.D., while a I.D. A regulator can reduce hose pressure to an air pressure thats lower than the systems air pressure. Unless someone clues you into the color guide though, how will you know which are which? Hey! A threaded boss is a threaded hole in the device or air tool into which you insert or thread a fitting. 0000010381 00000 n However, a 1-inch impact tool that needs 87.5 SCFM to operate properly will require a -inch or 1-inch I.D., depending on whether the hose length is 25 or 150 feet. 0000005799 00000 n To determine the size of a threaded airport in an air tool handle, air cylinder, valve, or the female thread in any compressed air component, you will want to measure the width of the hole in inches. 0000070619 00000 n Scs assumed (based on copyright claims)., Public domain, via Wikimedia Commons. 0000068911 00000 n This produces mixed results with low to high-level leakage depending on the thread sealant selected. Flexible air hoseshave different capacities.

Most compressed air system fitting sizes follow the NPT (National Thread Tapered) standard, while others use Metric fitting standards, both denote the thread size but are different. 0000034990 00000 n %PDF-1.4 % Automatic fittings allow you to plug your airlines indirectly and quickly seal the air opening when the hose or male part is removed, which allows for the O-ring or female connection to completely close.if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[580,400],'about_air_compressors_com-medrectangle-3','ezslot_1',118,'0','0'])};if(typeof __ez_fad_position!='undefined'){__ez_fad_position('div-gpt-ad-about_air_compressors_com-medrectangle-3-0')}; Manual couplers on the other hand require you to pull on the collar of the coupler to insert and remove the air hose. 0000256297 00000 n Yes indeed, it can be quite a dance to get from 1 to 1/4 in fittings. For more information or help in selecting a flexible air hose, please contact a technical adviser by calling 1-800-263-8677 or sending an email to [emailprotected]. Air compressor fittings are attachments that help maintain a consistent flow of air and pressure throughout a compressed air system. 0000089637 00000 n Check and be sure before buying into this concept. Abrupt changes in direction or any disturbance to the airflow will result in a loss of pressure. Since compressed air flows very rapidly, sometimes pieces of the Teflon tape can break off in the air turbulence inside the fitting and create problems downstream by lodging in other air components. . 0000089042 00000 n If that is not the case, protect them by installing a safety valve from Series 09. to help determine proper fit: Finding the thread size with a tape measure. The best thread seal tape for compressed air fittings is PTFE (polytetrafluoroethylene) sealant tape. The following reference table indicates the air flow rate (SCFM) based on the length/diameter correlation of the compressed air hose. affects the overall weight of the flexible hose and that each additional foot will add to it. 0000001897 00000 n If so, youre not It is not always easy to tell them apart. For example, pieces of tape can lodge in smaller air orifices and block them, or prevent another sealing surface from closing properly, actually generating a leak. When you disconnect an air hose, the coupler closes to prevent air from escaping. On this chart, I have listed the NPT thread size first, then what that thread size is in actual (decimal) inches, and then the closest common size fraction to that NPT size.Guide to NPT fitting size. If the elbow fitting is to be swiveling continuously, by a reciprocating part or some such on a machine, install a purpose-designed rotary union, NOT a swivel elbow fitting. l1C5LP1wHwP#6i{7_qBN66* 6` The threads on this style will likely be shorter in length than other types of metric fittings.

When buying an air compressor plug, quality and fit are the most important factors to consider, so its advised to opt for a brand with known quality to prevent compressed air leaks. 0000047456 00000 n 0000035509 00000 n

Part of the issue in finding a solution is to know what exactly you are attempting. By that I mean is it a 1 female threaded pipe to 1/4 male or female threaded what? Depending on what you have, this bushing https://www.shopcross.com/product/parker-1-x-14-ptr-s-pipe-bushing-1-inch-male-x-14-female-nptf-steel, or this reducer https://www.mcmaster.com/44605k387, will probably do the trick, maybe with a coupler or pipe nipple to get the sex right. Visit your favorite hardware or plumbing store and ask for a 1/4 fitting.

ANYTHING THAT INCORPORATES THE PURCHASED PRODUCTS, INCLUDING FULL AND COMPLETE RESPONSIBILITY AND LIABILITY FOR THE PROPER and had difficulty determining the thread size you need? Measure the OD (Outside Diameter) of the airline / tube to get the size. For a female thread, measure the top diameter of the opening (OD). When air consumption exceeds a preset value, an internal piston instantly cuts off the airflow and the air line. Do not make the assumption as I used to that a 1/4 NPT fitting thread is anywhere near 1/4 inch in diameter! Most flexible hoses are designed to withstand a pressure of at least 200 PSI. In other words, you will screw this fitting thread right down until the sealing ring or O-ring squishes between the body of the fitting wrench flats and the boss into which you are threading it, sealing in the compressed air. You will commonly see the following in NPT thread sizes; There are certainly much larger NPT sizes. Using the liquid on smaller fittings is problematic if care is not taken to keep the sealant from overlapping and blocking the actual air passage. For example, the pressure of an industrial compressed air system is usually between 90 and 150 PSI. NPT, as an acronym for National Pipe Taper, is an industry dimensional standard. delivers twice the flow of a 3/8. Just like couplers, plugs come in automotive, industrial, ARO, and V-style designs. use a tape measure or scale to measure the inside diameter (ID) of the threaded 0000255448 00000 n

0000256093 00000 n 0000079734 00000 n The overlapping tape can impede the air passageway. However, these are not tapered the same way as the NPT threads are, they are metric. If your tape measure shows the top (yellow) measurement then you need to order the measurement in the bottom (purple) area . /Height 82 To determine the right inside diameter, make sure you know how much air is needed (SCFM) to optimally power your pneumatic tool or equipment. 0000002872 00000 n This is a practical solution that prevents flexible air hoses from being dragged on the ground, keeping accidents at bay and reducing premature wear. The safest approach is to select a compressed air hose based on the fact that the flexible air hose will receive its air supply at the pressure of the compressed air system. The fitting they will show you will most likely be a 1/4 NPT. After determining your measurement choose the closest ID or carried by or in contact with the flexible hose must be compatible with the hose material. To find out more about flexible air hoses and the minimum inside diameter, download the Reference Table for Flexible Hoses per Pneumatic Tool Type and Air Consumption (PDF). obtained elsewhere and you don't know what the proper thread and airline sizes 0000255947 00000 n alone. This means you should choose a flexible hose based on the highest pressure it could receive, i.e., the maximum air pressure of the piping system itself. To determine the size of pipe fitting thread you need, first 0000036176 00000 n z3;a&Zuwv]wn:H3OMBgW:/;5YB+kzXs_]Hc(Sa'^ws[mM=1-6uuqm+qeJMHIhnouBT+xW:"ksed[ 4y6U\xu"KI} 6eXkvv/e[GzZOIf7f$}GVTT=j_B4 _|VP[nWEIS{ h {Ujeo9NUEG[2s~z@~"N_>`m!nvcucQ$/KmW~'W2Q7wMv;@>4i'vhpWsT4OeB'v0.&g z}$}mJF!dxf(obM-SoE1vn7wo`5cOe~/P Dtt Industriel Granby, Qubec J2J 1A4, How to choose a compressed air hose in 4 steps, Air Tank and Compressor Safety Check Valves, Reference Table for Flexible Hoses per Pneumatic Tool Type and Air Consumption (PDF), Average consumption (actual consumption may vary), Data for new flexible air hoses exempt of contaminants (water, rust, dust), Information based on a maximum 5 PSIG pressure drop, Cracking and breakage that causes air leakage, Also available with S79 Polyreel hose reel, Also available with S79 SteelPro, TopReel or TopReel HD hose reels, Lock-on fittings for easy maintenance and servicing, Also available with S79 ToopReel HD hose reel. %PDF-1.3 Couplers and plugs go hand in hand. 0000256004 00000 n THE USER ACKNOWLEDGES AND WARRANTS THAT IT BEARS FULL AND COMPLETE RESPONSIBILITY AND LIABILITY FOR THE FINAL DESIGN OF A flexible hoses resistance to pressure is a matter of safety. G-style fittings come in a variety of thread sizes, the commonest of which are: Larger sizes in the G-style metric fitting are certainly available, yet the sizes shown seem to be the highest volume in industrial compressed air applications. 0000070230 00000 n As a result, metric thread sizes are incompatible with their NPT same-sized counterparts. Compressed Air Information, Port size/fitting thread size into which the male thread is screwed, Size of tube or hose that you want to attach to the fitting; and note, tube, and hose do NOT connect the same way, Style of fitting; whether it is a straight, elbow, Tee, run Tee, etc. 0000002343 00000 n Just as its name suggests, the straight fitting accepts an airline (tube or hose) on one end, and on the other, there is an NPT male or female thread that screws into or onto a boss.
