Seals & Gaskets

O-ring material families

O-rings are available in EPDM, Neoprene, NBR, VMQ silicone, FKM, FVMQ and HNBR. Each material family serves different contact media and temperature requirements.

Choosing a compound

Start with the working medium, temperature and mechanical loading. NBR and HNBR are used for oil-contact sealing; EPDM is considered for water and weather-exposed interfaces. Silicone, FKM and FVMQ offer different combinations of temperature behavior and fluid resistance. Confirm compatibility for the selected compound.

Dimensions and installation

Provide the gland geometry, cross-section, diameter and required compression. Dimensions, hardness and finishing are selected for the assembly and checked using a representative sample.

Materials and forms

Gaskets can be converted from solid rubber, foam and suitable sheet materials. Material selection considers the contact medium, mating surfaces and required compression.

Custom profiles and backing

Outlines, internal openings and bolt-hole patterns can be developed around the assembly. Adhesive backing and laminated layers can support positioning or add a required function. Molding is considered for three-dimensional sealing geometry.

Information for selection

Include a drawing or sample, material preferences, thickness and the operating conditions. Confirm the gasket geometry and installed compression against the mating surfaces.

Continuous profiles

The product range includes EPDM, silicone, FKM, EPE foam and IXPE foam profiles. Material and cross-section are selected around the sealing, cushioning or protective function.

Assembly features

Continuous sections can be supplied as profiles, strips or tubes and cut to length. Joining, finishing and attachment features are reviewed for the selected material and the installation.

Developing a section

Provide the cross-section, installation space, required length and operating environment. The selected material and geometry should be evaluated at the intended compression and loading.

Rubber and foam sheet stock

Rubber and foam sheets support sealing, cushioning, insulation, vibration damping and surface protection. Select hardness or density, thickness and cell structure for the required function.

Conversion and lamination

Sheets can be cut into gasket outlines, pads and protective components. Adhesive backing and laminated layers are selected around the substrate and installation. The cutting route depends on the material and profile.

Specifying a component

Include the part outline, thickness, operating conditions and expected compression. Material grade and production method are reviewed together for the finished component.

Molded rubber components

SEAL produces compression-molded rubber parts in six material families: EPDM, Neoprene, NBR, Silicone, FKM and FVMQ. Material selection starts with the surrounding media, the operating temperature and the mechanical requirements.

Solid and foam options

Molded products are mainly solid. EPDM, Neoprene, NBR and Silicone can also be supplied in selected foam forms; FKM is mainly solid and FVMQ is supplied as solid rubber.

Manufacturing and finishing

• Compression molding and curing.
• Precision die cutting for sheet and shaped components.
• Laser, waterjet and oscillating-knife cutting where suited to the material.

Application-led selection

Use the compound and geometry to address compression sealing, vibration isolation, cushioning or protection. Check media compatibility and the actual compound specifications before finalizing a design.

Sealing tape materials

SEAL supplies EPDM, Neoprene, NBR, Silicone, EVA, PU foam, PVC foam, IXPE foam and shielding composites. Select by the function of the tape, the contact media, the temperature and the assembly surface.

Material form

EPDM, Neoprene, NBR and Silicone tapes are available in solid and foam forms. EVA, PVC and IXPE are foam materials; PU includes open- and closed-cell grades. Shielding tapes combine conductive substrates and adhesive systems.

Converting options

• Adhesive backing and lamination with film or support layers.
• Die-cut rolls, strips and non-standard shapes.
• Laser, waterjet and oscillating-knife cutting when required.

Application conditions

The foam structure, adhesive and compression should be matched to the substrate and service environment. Compound and adhesive performance depends on the selected grade and assembly conditions.
