How does the 45° JIC Interlock Female UNF End, Carbon Steel ensure leak-free performance under extreme pressure?

The 45° JIC Interlock Female UNF End, Carbon Steel ensures leak-free performance under extreme pressure through a combination of design, materials and protective features: - 74° cone with integrated O‑ring: the cone creates a metal-to-metal seating surface while the O‑ring provides a secondary elastomeric seal, sealing gaps and compensating for minor surface imperfections to prevent fluid escape under high pressure. - Interlock construction: the interlock design mechanically locks the hose to the fitting, eliminating movement at the joint, maximizing pull‑off resistance and maintaining consistent compression on the sealing surfaces even under cyclic or shock loads. - Precision 45° geometry: accurate angle and thread engagement ensure uniform contact and proper torque distribution, reducing uneven stress that can cause leaks. - Carbon steel body with galvanization: high-strength material resists deformation under extreme pressure; the protective zinc coating reduces corrosion and wear that could compromise the sealing surfaces over time. - Compatibility with high‑pressure hoses (4SH, R13, R15): matched components maintain hose reinforcement alignment and minimize stress concentrations, preserving seal integrity in heavy‑duty environments. Together, these features deliver robust, durable sealing and retention to minimize leakage risk in demanding hydraulic systems.
