How does the ES4 stainless steel jam ring with sealing gasket prevent leaks caused by metallic seal loosening in DIN 2353 connections?

The ES4 stainless steel jam ring with sealing gasket prevents leaks from metallic seal loosening in DIN 2353 connections by replacing the single metal-to-metal seal with a dual-component, elastomer-backed solution. Its profiled seal provides a precise metal interface while the additional O-ring seated in the cone recess creates an independent elastomeric barrier. If the metallic element relaxes or creeps under load or temperature changes, the O-ring maintains contact and compensates for micro-movements, eliminating the leakage paths typical of traditional metal seals. Built for both L and S series, the AISI 316 construction and Viton seal ensure long-term dimensional stability, chemical resistance and temperature tolerance, so the assembly keeps absolute tightness and operational continuity even under demanding conditions.

Can the ES4 stainless steel jam ring with sealing gasket be retrofitted into existing DIN 2353 fittings to prevent leakage from metallic seal loosening?

Yes — the ES4 stainless steel jam ring with sealing gasket can be retrofitted into existing DIN 2353 fittings to prevent leakage from metallic seal loosening. Its profiled seal plus an additional O‑ring in the cone recess replaces the traditional metal-to-metal seal, eliminating leakage risks caused by relaxation or creep of the original metallic seal. Designed for both L (light) and S (heavy) series, the ES4 fits standard DIN 2353 connections and delivers long-lasting performance under demanding conditions. Made from AISI 316 stainless steel with a high-quality Viton seal, it also adds corrosion, temperature and media resistance, ensuring improved durability, safety and operational continuity.
