Custom Made EPDM, NBR, FKM Rubber Gaskets
Our custom-made rubber gaskets are high-precision engineering sealing components formulated to solve leakage problems across industrial, automotive, and municipal fluid-control systems. Utilizing high-grade elastomers including EPDM, NBR, and FKM (Viton®), these custom profile gaskets provide a rugged seal against extreme pressures, temperature variances, fluid media chemical attack, dust, and moisture entry.
Haiyixin offers comprehensive, budget-friendly rubber tool prototyping and contract manufacturing services with incredibly flexible low MOQs. We can rapidly translate basic hand-labeled dimensional drawings or professional CAD files into elite custom sealing components.
Selecting the right elastomer material is critical to expanding your equipment life cycle. Below is our standard engineering evaluation criteria chart for our three major custom sealing materials:
| Elastomer Type | Working Temp Range | Primary Advantages & Best Industrial Applications |
|---|---|---|
| Ethylene Propylene (EPDM) | -60°F to 300°F | Outstanding resistance to weathering, ozone, UV, hot water, and steam. Best for municipal drinking water infrastructure, plumbing valves, and HVAC systems. |
| Buna Nitrile (NBR) | -40°F to 250°F | Exceptional oil, petroleum fuel, solvent resistance, and high mechanical tear strength. Best for automotive fuel lines, industrial hydraulic systems, and gearboxes. |
| Fluoroelastomer (FKM / Viton®) | 0°F to 390°F | Ultimate protection against extreme temperatures, harsh mineral acids, aromatic hydrocarbons, and oils. Best for aerospace, chemical petrochemical processing kettles, and high-pressure oil & gas equipment. |
For custom industrial rubber parts production, our standard turnaround time is 15-20 calendar days. This comprehensive phase covers technical dimensional confirmation, custom tooling/mold creation, compound mixing, compression injection molding, and batch quality inspection. Reorders feature a shortened cycle because your project molds are stored securely in our archive.
Our premium compound mixtures satisfy international public health directives and strict mechanical engineering compliances, including DVGW, KTW-BWGL, WRAS, ACS, and FDA standard requirements:
Q1: How do I know whether EPDM, NBR, or FKM is best for my custom gasket design?
A1: Material choice depends on the application medium. Choose EPDM for hot water/steam or weathering; NBR for oils, fuels, and intense wear; and FKM for harsh industrial acids or temperatures soaring up to 390°F.
Q2: What is your minimum order volume for non-standard molded rubber gaskets?
A2: We support extremely flexible low MOQs for initial runs. Provide your CAD files or physical samples, and our application engineering department will work closely with you to offer the best custom solution.
Whether you require a standard plumbing washer batch or specialized, high-performance custom-engineered EPDM, NBR, or FKM rubber gaskets, our engineering sales group is here to help.

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.
