Seals & gaskets

Seals & gaskets

A comprehensive inventory of rubber seals, trims and gaskets in a wide range of profiles, materials and sizes for industrial sealing applications. Materials include NBR, EPDM, silicone and FKM; products are specified for static and dynamic sealing, weather protection, dust exclusion and vibration isolation. Technical data covers durometer, temperature range, chemical compatibility and dimensional tolerances to support engineering selection.

For sheet and profile options see our flat seals and gaskets collection. Contact our technical team for material selection, extrusion tolerances, application-specific specification review or bespoke sealing design support and compatibility checks.

We can supply Seals & gaskets in virtually any design and specification.

Custom production is possible based on technical drawings, material requirements, or performance criteria.

Seals & gaskets — types and materials

Seals and gaskets are used to control fluid, gas and particulate ingress or egress across a wide range of industrial and marine applications. Common product types include O-rings, flat gaskets, flange gaskets, molded seals, extruded profiles and trim. Typical elastomer and polymer choices specified for these functions include NBR (nitrile), EPDM, silicone, neoprene, fluorocarbon (FKM/Viton) and PTFE, with each material offering different resistance to temperature, chemicals and abrasion. Selection of material and design is typically driven by the operating medium, temperature range, surface finish and required sealing class.

Selection, sizing and technical support for seals and gaskets

Appropriate selection requires attention to geometry, cross-sectional profile, hardness (shore), compression set and mounting conditions. Technical information such as dimensional tolerances, compatibility charts and material data sheets can be requested to support specification and procurement decisions; certificates and test reports may be available depending on the product. Custom sizes and bespoke profiles can often be produced to customer drawings or samples. For examples of industry-standard flat gasket options, see the seals and flat gaskets collection. RuplaTec supplies technical rubber and plastic products for industrial and marine use; contact our team for advice on material compatibility, sizing or installation considerations.

FAQ

What types of seals & gaskets are offered for industrial applications?

Seals & gaskets are supplied in a range of constructions to address common sealing requirements, including rubber seals, trims and flat gaskets suitable for static and dynamic joints. Products include standard profiles, cut-to-length seals and assembled gasket shapes intended for panel, door and equipment sealing. Materials and constructions vary to suit different operating conditions; specify the intended application and media when enquiring so the appropriate type and material can be recommended.

How do I select the correct rubber seal or gasket for my application?

Selecting an appropriate rubber seal or gasket requires consideration of operating temperature, fluid or gas compatibility, pressure, expected compression and the mating surface finish. Also assess whether the application is static or dynamic and whether chemical, ozone or UV resistance is required. Provide details of the operating environment and functional requirements to determine material compatibility and profile. Our team can assist with technical advice if you supply application parameters and performance criteria.

Can seals and gaskets be supplied in custom sizes or profiles?

Yes, seals and gaskets can be supplied both as standard off-the-shelf items and as bespoke components to meet specific size or profile requirements. Custom options commonly include cut-to-length seals, modified profiles and assembled gasket shapes for non-standard openings. When requesting a custom solution, provide drawings, cross-sections or sample parts and state material and performance needs. Contact our team for guidance on feasibility and technical details during the specification process.

What are common causes of seal and gasket failure and how can they be prevented?

Common causes of failure include material incompatibility with the service media, excessive compression or abrasion, improper installation, and degradation due to heat, ozone or chemicals. Prevention measures include selecting compatible materials, ensuring correct groove and compression specifications, following recommended installation practices, and performing regular inspections. Where maintenance or material selection is uncertain, provide operating conditions and failure symptoms to our team for technical advice on root cause analysis and suitable replacement options.
