Our Parker metal Seal-Lok -Ring Face Seal Tube Fittings are been shown to be every effective in eliminating leakages during the greater pressures present today’s hydraulic systems. Made to eradicate leaks and provide a more protected connection than standard compression fittings in high-pressure applications, these fittings include a captive -ring regarding the body for https://www.kplokusa.com the fitting that reinforces the seal whenever nut is tightened on fitting. See Figure 1. The ranked working stress of a fluid conductor installation using SAE J1453 hose stem connections or formed tube connection per Figure 32a, shall perhaps not surpass rated working pressure of lowest rated component thereof.
The flat, perpendicular sealing areas associated with the human anatomy plus the sleeve (or flanged tube end) result in a perfect leak-free joint. In the event that elements within hydraulic systems never ever had to be removed, connections could be brazed or welded to maximize dependability. The feminine has a right thread and a machined flat face.
The current innovation is a better -ring seal flat face fitting regarding the type having a male portion including an -ring, and women part having a tube with an internal diameter, a protracted peripheral limitation having a diameter corresponding to said inside diameter, a nut, and a joinder part. When creating ORFS connections, very first make sure that the -ring is properly seated into the groove.
Hyd-air olive type compression fixtures consist of a nut, and olive and a human body. Unlike Flareless Fittings which allow just 15 remakes or flared fittings which nose distortion ultimately causes leakages, the soft seal of the -ring on a Flat Face Fitting permits limitless remakes providing some resilience is kept in the rubber.
Tightening the locknut additionally forces a captive back-up washer onto the -ring, which forms the leak-tight seal. Accordingly, there is an ongoing need for an -ring seal flat faced fitting, including a female portion, of simplified construction that a better resistance to leakage attributable to loosening caused by twisting of this tube.
Threads on pipe fixtures are tapered and rely on the stress created by forcing the tapered threads associated with male half the fitting in to the female half or component slot, Figure 1. Pipe threads are susceptible to leakage because they’re torque-sensitive – over-tightening distorts the threads excessively and creates a path for leakage round the threads.
