The right material for every application
From food-grade polyurethane to high-temperature PTFE, we select and specify materials based on your exact operating conditions.
Seal material reference
| Material | Temperature | Chemical Resistance | Key Applications |
|---|---|---|---|
| PTFE | -200°C to +260°C | Excellent (virtually universal) | Chemical processing, pharmaceutical, food contact |
| Polyurethane (PU) | -30°C to +80°C | Good (oils, greases) | Hydraulics, pneumatics, dynamic seals |
| Silicone (VMQ) | -60°C to +200°C | Good (ozone, weathering) | Food & beverage, pharmaceutical, static seals |
| Nitrile (NBR) | -30°C to +100°C | Good (oils, fuels) | General industrial, hydraulics, pneumatics |
| FKM (Viton) | -20°C to +200°C | Excellent (chemicals, fuels) | Chemical processing, high-temperature, aerospace |
| EPDM | -40°C to +150°C | Excellent (steam, CIP chemicals) | Dairy, food processing, water treatment |
| PEEK | -60°C to +250°C | Excellent | High-performance bearings, back-up rings |
| Acetal (POM) | -40°C to +100°C | Good | Precision components, piston heads, guide rings |
How we design and manufacture
Specialist Seal Design Software
Proprietary software for modelling seal profiles, material behaviour under operating conditions, and tolerance analysis. This is not generic CAD: it is purpose-built for sealing applications.
CAD Design & 3D Modelling
Full 3D modelling capability for complex geometries, custom profiles, and multi-component seal assemblies. Design files can be shared with your engineering team for integration.
CNC Machining
Precision CNC machining of engineering plastics and polymers for prototype and production seals. Complex cross-sections and tight tolerances are standard capability.
Compression Moulding
Elastomer seals produced via compression moulding for production volumes. Tooling costs are modest compared to injection moulding, keeping custom seals cost-effective.
Material Testing
We can advise on material compatibility testing for your specific media, temperature, and pressure conditions. Getting the material right first time avoids costly field failures.
Full Documentation
Material certificates, declarations of conformity, batch traceability, and compliance documentation supplied with every order. Your quality team gets what they need.
