Flat rubber gaskets and washers are thin, high-precision elastomeric sealing components produced by advanced vulcanization compression molding to fit perfectly between two mating surfaces. When compressed, they create a reliable watertight and airtight seal, seamlessly filling microscopic gaps to prevent any media leakage. Specially formulated for international sanitary safety compliance, our high-performance rubber washers offer superior compression set resistance and long service life in public water supply systems and high-end industrial valves.
Our sealing compounds are strictly tested and approved under global regulatory standards for safe drinking water and gas applications:
| Certification / Standard | Region | Scope & Focus Area | Compliance Status |
| DVGW | Germany / EU | Gas and Water Supply Systems | Certified - Meets the highest safety and quality requirements for technical components. |
| KTW-BWGL | Germany | Organic Materials in Contact with Drinking Water | Compliant - Passes stringent chemical leaching tests to ensure water purity. |
| W270 | Germany | Microbial Growth Assessment | Passed - Proven to inhibit the growth of bacteria and biofilms on material surfaces. |
| EN 16421-1 | European Union | Enhancement of Microbial Growth (EMG) | Certified - Verified resistance against microbial proliferation in piping systems. |
| WRAS | United Kingdom | Water Regulations Advisory Scheme | Approved - Mandatory compliance for non-metallic materials in the UK water industry. |
| ACS | France | Attestation de Conformité Sanitaire | Approved - Certified by the French Ministry of Health for safe drinking water contact. |
