Functionally qualified to MS, AN, JIC/SAE standards, SAE 37° Flared fittings enjoy widespread familiarity as adapters to hose assemblies & fittings for thin to medium wall thickness, dynamic pressurized tubing lines. With many sources of supply, SAE 37° Flared fittings are one of the more economical fittings for the budget-conscious consumer. Compared to other metal-to-metal fitting systems, SAE 37° Flared fittings rate "average" for remake ability and ease of assembly. Available from stock to 2" OD in stainless and 1" OD in Monel and brass.
Flared Fitting Specifications
UltraFlare tube fittings are recommended to users familiar with SAE 37° Flared fittings, but seeking a reliable seal in less-than-optimal assembly conditions. Using a primary PTFE seal reinforced by metal-on-metal, UltraFlare requires less make-up torque than standard SAE flare. As such it allows more remakes and compensates for under torqued make-ups (compared to published standards). The location of the PTFE seal also permits a positive seal on partially underflared tubing - not recommended, but if it's a situation encountered in fabrication, UltraFlare may provide the solution. PTFE seal improves performance in mild vacuum and moderate vibration on thin and medium-walled tubing systems. Available from stock in stainless steel to 1" OD.
