Manufacturing & Quality Standards
Priyanshi Fasteners double-ferrule design ensures that the front ferrule seals against the fitting body and tube outer diameter, while the back ferrule mechanically grips the tube. This dual-action mechanism prevents vibration transfer and tube blowout. All fittings feature silver-plated nut threads to prevent galling during assembly.
