Dual-Mechanism Sealing:
Mechanical Bite: The hardened metallic sharp edge bites precisely into the outer wall of the hydraulic tube, creating a form-locked mechanical hold capable of withstanding extreme tensile forces.
Elastomeric Soft Seal: The embedded profile ring captures micro-imperfections on the tube surface and fitting body, providing an airtight barrier that standard metal-to-metal seating cannot guarantee.
Superior Vibration and Shock Absorption: The elastomeric compound acts as a built-in damper, absorbing continuous system pulsations and hydraulic shocks. This significantly extends the service life of both the tubing and the fitting connections.
Premium Surface Protection (CrVI-Free): Standard carbon steel variants are treated with an advanced Zinc-Nickel (Zn-Ni) plating, providing over 720 hours of red rust resistance under ASTM B117 salt spray testing.
Zero Post-Assembly Tweaks: The high tolerance precision reduces assembly errors, drastically lowering time spent on post-installation inspections, troubleshooting, or rework.
