Does the ES4 Jam Ring with Gasket, Carbon Steel, Zinc-Nickel Coated prevent leaks if the metal seal loosens due to material creep?

Yes. The ES4 Jam Ring with Gasket, Carbon Steel, Zinc-Nickel Coated prevents leaks even if the metal seal loosens due to material creep. Its profiled gasket integrated into the cone recess plus an additional O-ring provide a secondary elastomeric sealing barrier that compensates for metal relaxation. Built with a high-performance Viton seal and robust carbon steel body, it maintains reliable sealing under creep conditions. The zinc-nickel coating (6–10 µm) adds corrosion resistance for long-term integrity, and availability in both L (light) and S (heavy) series ensures compatibility with various DIN 2353 hydraulic applications.

How does the ES4 Jam Ring with Gasket, Carbon Steel, Zinc-Nickel Coated maintain sealing performance under extreme temperature cycling and long-term creep?

ES4 Jam Ring with Gasket, Carbon Steel, Zinc-Nickel Coated maintains sealing performance under extreme temperature cycling and long-term creep through a multi-layered, fail-safe design: - Profiled gasket integrated into the cone recess plus an additional O‑ring: the dual elastomeric seals absorb differential movement from thermal expansion/contraction and take up deformation caused by long‑term creep, preventing voids that lead to leakage. - Metallic backup seal mitigation: the elastomeric gasket and O‑ring remain the primary sealing elements even if the metallic contact loosens from creep, eliminating leak paths that would occur with a purely metal seal. - High‑performance Viton seal material: Viton retains elasticity and chemical stability across wide temperature ranges, preserving compression set resistance and sealing force during repeated thermal cycles. - Robust carbon steel body and precise profiling: mechanical stability and tight tolerances ensure consistent loading of the gasket/O‑ring over time, limiting progressive relaxation or extrusion under sustained stress. - Zinc‑nickel coating (6–10 µm): protects the ring from corrosion that could undermine seal faces or cause increased wear during thermal movement; proven to withstand up to 720 hours in salt spray testing. Combined, these features allow ES4 Jam Ring with Gasket, Carbon Steel, Zinc-Nickel Coated to sustain reliable sealing performance under extreme temperature cycling and long‑term creep in demanding hydraulic applications.
