Design & Materials
The fitting housing is made from 316 stainless steel for superior corrosion resistance. Internal o-rings use a PTFE-coated nitrile compound that handles temperatures from –10 °C to 80 °C. Tapered sealing surfaces and precision aluminum spacers enhance durability and reduce wear, while electropolished surfaces minimize particle adhesion.
Performance & Installation
Bench tests demonstrate efficient volumetric flow with a Cv coefficient of 0.65. Burst pressure ratings exceed 6000 psi. Install using a calibrated torque wrench (35–40 N·m), either vertical or inline. Ensure proper purge before connecting to avoid debris infiltration.
