Rubber hatch seals - All types & sizes

The range of Hatch Seals includes composite and solid rubber profiles in EPDM, NR/SBR and nitrile (NBR) compounds, offered in common cross-sections such as 30×20mm, 30×25mm and solid 30×55mm reels. Profiles are formulated for compression sealing on hatches, inspection ports and access panels; material choices provide weather/ozone resistance (EPDM), general-purpose resilience (NR/SBR) and oil/fuel resistance (NBR).

Typical applications include marine, industrial and transport hatches where watertight and dust-tight performance is required; seals are supplied in standard lengths and can be specified for custom sizes.

Hatch Seals: applications and material types

Hatch seals are used to provide compression sealing for access hatches, doors and deck openings in marine and industrial environments. Common elastomer families encountered in hatch seals include EPDM, NR/SBR and nitrile (NBR), each offering different resistance characteristics relevant to weathering, oils and general mechanical wear. Examples in this product area include RubbaHatch Composite EPDM Hatch Seal – 30mm x 20mm, RubbaHatch Composite NR/SBR Hatch Seal – 30mm x 25mm x 10m and Nitrile Solid Rubber Seal – 30mm x 55mm x 5m. Selection of material should consider the operating environment, contact media and expected mechanical loads.

Hatch Seals selection, dimensions and technical support

When specifying hatch seals, typical criteria include cross‑section profile, compression set, hardness range, and available lengths or coil formats. Profiles are often selected to match the hatch frame detail and the required compression gap; dimensional data and sample pieces can be requested where needed. Technical information such as chemical compatibility guidance, suggested installation methods and cut‑length options may be provided on request. For a full overview of sizes and profile types see the rubber hatch seals collection.

FAQ

What materials are available for Hatch Seals and how do their properties differ?

Hatch Seals are commonly manufactured from elastomers such as EPDM, nitrile (NBR), natural rubber or NR/SBR blends, and composite constructions combining different rubbers and fabrics. EPDM is generally selected for weather, ozone and temperature resistance. Nitrile is chosen where oil, fuel or hydrocarbon resistance is required. NR/SBR and blends are used for general-purpose sealing with good flexibility. Material selection should be based on the specific chemical, thermal and mechanical exposures of the application; contact our team for material advice.

How do I choose the correct Hatch Seal profile for my application?

Selecting a Hatch Seal profile requires assessment of the joint geometry, expected compression and rebound, movement or vibration, and the mating surface. Profiles vary between solid, hollow or composite sections to provide different sealing forces and deflection characteristics. Consider chemical and temperature exposure alongside mechanical load to ensure compatibility. Prototype fitting and compression testing under representative conditions are recommended. For profile recommendations matched to your application parameters, contact our team for technical guidance.

What are the recommended installation and maintenance practices for Hatch Seals?

Installation methods include adhesive bonding, mechanical fastening or compression-fit into grooves, depending on the seal profile and panel design. Surfaces should be clean and dry before installation and continuous contact should be ensured along the sealing line. Routine maintenance comprises regular inspection for extrusion, cracking, hardening or loss of elasticity, and cleaning with mild, non-solvent detergents. Replace seals that show permanent deformation or material degradation. For installation instructions specific to a chosen material and profile, contact our team.

Can Hatch Seals be supplied to custom lengths or with specific profiles?

Hatch Seals are typically available in a range of standard profiles and can be supplied cut to length, spliced or supplied in continuous form depending on manufacturing options. Custom profiles may be specified where standard sections do not meet application requirements; this can involve tooling or composite construction. When requesting custom work, provide application details such as mating geometry, environmental conditions and expected loads. Our team can advise on feasibility and technical requirements for bespoke Hatch Seals.
