Super Flangeless™ Fittings from IDEX Health & Science are the high-performance successor to standard flangeless fittings. They are specifically designed to withstand the highest possible pressure in flat-bottom ports, without having to flange the tubing.
Extremely pressure resistant: Depending on the configuration, resistant to pressures up to 10,000 psi (690 bar).
Torque-free design: The system uses a separate ferrule and a stainless steel locking ring. As a result, the tubing does not rotate while tightening, which prevents leaks and internal stress.
Vibration resistant: The unique lock ring prevents fittings from loosening due to vibrations from pumps or motors.
Reusable: The fittings can be loosened and retightened repeatedly without loss of sealing quality.
