FAQ What is the maximum working pressure for this fitting?The maximum working pressure for the SERTO SO 51021 series in stainless steel for 6mm tubing is typically up to 250 bar (3625 PSI), depending on the tubing material and wall thickness. Always consult the official SERTO datasheet for your specific application’s pressure and temperature ratings. Is this fitting compatible with tubing from other manufacturers like Swagelok?While dimensionally similar to other twin-ferrule fittings, it is strongly recommended not to mix and match components (nuts, ferrules, bodies) from different manufacturers. Doing so can compromise the integrity of the seal and void warranties. For guaranteed performance, always use SERTO components together. What are the correct assembly instructions to ensure a leak-proof seal?For proper assembly, insert the tube into the fitting until it bottoms out against the shoulder. While holding the fitting body steady with a wrench, tighten the nut 1 and 1/4 turns from the finger-tight position. This ensures the ferrules swage correctly onto the tube, creating a secure seal. profideals is not an authorized distributor, reseller or representative of the products featured on this website.
