America hydraulic connector JIC (37° Flare) The Society of Automotive Engineers (SAE) specifies a 37° angle flare or seat be used with high pressure hydraulic tubing. These are commonly called JIC couplings. The JIC 37° flare male will mate with a JIC female only.* The JIC male has straight threads and a 37° flare seat. The JIC female has straight threads and a 37° flare seat. The seal is made on the 37° flare seat. Some sizes have the same threads as the SAE 45° flare. Carefully measure the seat angle to differentiate.
we supply hydraulic connectors not only standard but also comply with customers drawings.we devoted ourselves covering most ofEuropeand theAmericasmarket.These hydraulic fitting Products are widely used in construction machinery,automotive manufacturing,industrial pipelines,ships,energy,national defense,automation and other fields.
1. The hydraulic connected thread has three types:NPT,NPTF and BSPT.
2. NPT,BSPT threads should be assembled with sealant.NPTF is metal to metal seal,but use sealant also.Sealants are available in various forms such as Teflon tape,paste and anaerobic gule etc.
3. Teflon tape,paste etc.,if applied improperly,they will pollute the oil of the hydraulic system,even jam the system.
4. The seal of the small thread is better than large.In general the seal of less than 3/4”are good.
5. The connect will compact when the taper thread for straight fitting,if for eblow or tee or cross fittings,the assemble angle is difficult to contron,so sugguest that the adjustable stud end fittings should be used,for example ISO6149,ISO11926 etc..
1. Inspect port and connection to ensure that threads on both are free of dirt,burrs and excessive nicks.
2. Apply sealant to male pipe threads.With any sealant,the first and second threads should be uncovered the avoid system contamination.If Teflon tape is used it should be wrapped 1.1/2 to 2 turns in clockwise direction when viewed from the pipe thread end.
3. Firs tighten the fitting with hand,then tighten with a wrench 1.1/2 th 3 turns. In general,the small fitting is tighten about 2.5 turn and the large fitting is tighten about 2 turns.
The taper thread fitting can be reassembled. When reassembled,check if sealant has worn thin.
1. There is no sealant used or sealant has worn thin.
2. Threads are galled.
3. Fitting screws in too far into the port.
