Custom rubber gaskets and washers seal the joint between two surfaces to stop leaks of fluid, gas, or dust. At Anlintech we manufacture sheet, spiral-wound, ring, and fully custom-molded gaskets in FKM/Viton, EPDM, NBR, silicone, and neoprene—engineered to your flange, ID/OD, and pressure specification. Read our complete guide to custom rubber gaskets for the full material and manufacturing breakdown.
| Material | Best For | Temp Range |
|---|---|---|
| NBR (Buna-N) | Oil, fuel, hydraulic fluid | -40°C to +120°C |
| EPDM | Steam, weather, ozone | -50°C to +150°C |
| Silicone | Food, medical, high temp | -60°C to +230°C |
| FKM / Viton® | Chemicals, fuel, heat | -20°C to +205°C |
| Neoprene | Weather, flame, moderate oil | -40°C to +120°C |
Standards such as ASTM and ISO define gasket material and dimensional tolerances we hold to.
Compare materials in our EPDM vs NBR vs FKM and FKM vs Viton vs FPM guides.
We compression- and injection-mold gaskets, and can die-cut sheet stock for prototypes. See the gaskets pillar guide for tolerances and process detail, or our silicone vs rubber gaskets comparison.
A gasket seals against leakage between joined surfaces; a washer is typically a flat spacer that distributes load or prevents loosening. Rubber washers also provide light sealing.
FKM/Viton® serves up to ~205°C; silicone up to ~230°C for dry heat. Choose based on chemical exposure as well as temperature.
Yes. Send a 2D drawing or sample and we mold or cut to your exact ID/OD, thickness, and durometer.
Yes—silicone and EPDM grades meet FDA and 3-A requirements for food and beverage lines.
