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.
Profile Rubber-Steel Gaskets G-ST-P/S (DVGW & WRAS Approved)
The rubber-steel gasket Profile G-ST-P/S series consists of a solid steel ring reinforcement encapsulated on all sides by premium vulcanized rubber. This specialized structural design ensures that the steel core is completely insulated from environmental corrosion and aggressive fluid media. Advanced factory vulcanization guarantees a high level of permanent adhesive strength between the elastomer casing and the heavy steel ring insert.
Engineered for high-security applications, our composite gaskets carry multiple public health and safety certificates. They strictly comply with European drinking water directives including DVGW KTW-BWGL, EN16421, ACS, WRAS, and BELGAQUA, as well as rigorous gas supply infrastructure sealing mandates like EN682 and EN549.

Q1: What are the insert specifications of your G-ST-P/S profile gaskets?
A1: Our profile gaskets utilize a centrally positioned, non-welded solid steel ring insert conforming to S235JR (St 37-2). This ensures maximum blowout defense and structural integrity under aggressive torque settings.
Q2: Are these rubber-steel reinforced gaskets compatible with gas pipelines?
A2: Yes. When formulated with our NBR compound, the gaskets fully satisfy DVGW EN682 and EN549 certificates, making them completely safe for fittings and check valves conveying gases or volatile hydrocarbon liquids.
