DVGW certified NBR rubber gaskets & washers with official EN682 and EN549 compliance for industrial and municipal gas supply applications. Formulated with ultra-low gas permeability, these premium nitrile seals ensure superior hydrocarbon gas-tightness and prevent volatile micro-leakage across natural gas pipelines, control valves, regulators, and heating appliances. Prototype Production & Testing: We manufacture a diagnostic batch of custom gas-grade prototypes using advanced molding. Each component undergoes rigorous blueprint dimensional validation and intensive hydrocarbon media resistance testing to ensure absolute field safety before implementation. Mass Production & Quality Control: Upon final prototype layout verification, mass compression production begins under strict ISO-certified quality protocols. Every batch is tightly inspected for precise durometer limits, gas-tight sealing recovery, and cross-sectional stability. Delivery & After-Sales Support: We arrange global timely delivery via international logistics networks (DHL, FedEx, sea freight) with full compliance data. Comprehensive after-sales tracking includes specialized installation alignment guidance and full-lifecycle performance follow-ups.

Rubber-steel Gaskets Profile G-ST The rubber-steel gasket Profile G-ST consists of a steel ring which is surrounded on all sides by rubber. The steel ring is protected from corrosion and media. Vulcanisation guarantees a high level of adhesive strength between the rubber and the steel ring. Potable Water approvals DVGW KTW-BWGL, EN16421, ACS, WRAS, BELGAQUA. As well as in the field of gas supply sealing approvals EN682, EN549.

Oil-resistant NBR rubber gaskets & washers for industrial applications. Ensure tight seals, prevent leaks, and withstand harsh chemicals. Ideal for machinery, pipelines, and automotive use. Durable, reliable, and easy to install. Prototype Production & Testing: We produce a small batch of prototypes using advanced molding technology. The prototypes undergo rigorous testing, including dimensional accuracy checks, oil resistance testing, and sealing performance testing, to ensure they meet your expectations. Mass Production & Quality Control: Once the prototype is approved, we start mass production with strict quality control measures. Every batch is inspected for dimensional accuracy, material properties, and sealing performance to ensure consistency. Delivery & After-Sales Support: We arrange timely delivery via international logistics (DHL, FedEx, sea freight) and provide comprehensive after-sales support, including installation guidance and performance follow-up. We also offer a warranty for custom products.
