EPDM Rubber Gaskets For Drinking Water Valves & Check Valves
Our custom-made EPDM rubber gaskets are precision-engineered sealing components designed to meet the unique and strict requirements of drinking water valves, check valves, and water treatment systems. Crafted from high-quality, certified elastomers, these gaskets deliver reliable, long-lasting protection against leaks, contamination, and environmental degradation.
Haiyixin specializes in custom rubber molding with low minimum order quantities (MOQs). Whether you have a professional CAD file or a basic hand drawing with dimensions, our engineering team can convert it into premium sealing solutions at the best value.
While EPDM is the ideal choice for drinking water applications due to its outstanding certification compliances (WRAS, KTW, FDA), we also manufacture custom gaskets in various other high-grade elastomers depending on your specific operating environment:
| Material Type | Temp Range | Key Features & Best Applications |
|---|---|---|
| Ethylene Propylene (EPDM) | -60°F to 300°F | Best for Drinking Water. Excellent weather, ozone, and steam resistance; complies with global water certifications. (Poor for petroleum oils). |
| Natural Rubber (NR) | -60°F to 220°F | Excellent compression set, high resilience, and good abrasion resistance. Poor chemical and UV resistance. |
| Buna Nitrile (NBR) | -40°F to 250°F | Superior oil, fuel, and abrasion resistance. Ideal for hydraulic and automotive systems. Moderate weather resistance. |
| Hydrogenated Nitrile (HNBR) | -40°F to 300°F | Enhanced heat, oil, and ozone resistance compared to standard Nitrile. Suitable for aggressive industrial media. |
| Fluoroelastomer (FKM / Viton®) | 0°F to 390°F | Ultimate chemical and high-temperature resistance. Ideal for petroleum oils and harsh acids. Poor low-temp flexibility. |
| Silicone (VMQ) | -90°F to 430°F | Exceptional extreme temperature flexibility. Low odor/taste, making it ideal for medical or specific water applications. |
| Neoprene (CR) | -40°F to 250°F | Good general-purpose resistance to ozone, UV, and refrigerants (Freon/Ammonia). Moderate water resistance. |
For standard and custom rubber parts runs, our typical turnaround lead time is 15-20 calendar days. Within this period, we handle the complete process: tool/mold creation, raw compound formulation and mixing, precision molding, and final quality control testing. Reorder lead times are substantially faster since your custom molds are securely cataloged and stored on-hand.
Our drinking water grade EPDM gaskets strictly comply with global public health and engineering standards, certified by top authorities to ensure resistance to microbial growth and zero toxicity contamination:
Q1: Are your EPDM gaskets safe for municipal drinking water systems?
A1: Absolutely. Our drinking water grade EPDM gaskets comply with major global safety standards, including WRAS, DVGW KTW-BWGL, ACS, and FDA 21 CFR 177.2600, ensuring they do not affect water taste, odor, or safety.
Q2: What info is needed to request a custom molded rubber valve seal quote?
A2: Please provide your technical CAD drawings or detailed dimensions (inner/outer diameter and thickness), along with your preferred elastomer material, application working temperature/pressure, and the required order quantity.
Whether you need standard sized or bespoke custom-engineered EPDM rubber gaskets, washers, or technical advice for your plumbing valves, we are ready to assist. Contact our engineering team today to discuss your technical specifications, request an obligation-free quotation, or acquire material samples.
Let us provide the high-performance compliance seals required to keep your water infrastructure running smoothly.
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.

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.
