Material selection

Marine gasket and sealing solutions

Material selection depends on media, temperature, pressure, compression and environmental exposure. Our team can help you evaluate the options.

EPDM Gaskets

Weather- and UV-resistant sealing for hatches, access panels and exposed marine applications.

Foam Gasket Image

Open- and closed-cell materials for weather sealing, gap filling, cushioning and vibration control.

Nitrile (Buna-N) Rubber

Resistance to diesel, biodiesel, oils and petroleum-based hydraulic fluids. Ideal for machinery and marine fuel systems

NSF Gasket Cut

Weather- and UV-resistant sealing for hatches, access panels and exposed marine applications.

Compressed Sheets Rolls

Sheet gasket materials for piping, pumps, valves and general marine mechanical systems.

High-performance gaskets for demanding temperature and pressure applications on flanged connections.

Weather- and UV-resistant sealing for hatches, access panels and exposed marine applications.

Reduce sourcing uncertainty


Keep sealing problems and unavailable parts from slowing the work


Saltwater, moisture, movement, weather and changing temperatures can be demanding on sealed components. Older equipment and unusual designs can make replacement parts difficult to source.

Leakage or premature seal failure
Obsolete, worn or unusual gasket designs
Long lead times for low-volume custom parts
Uncertainty about the right material
Prototype, replacement and production needs
