Materials & products


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 & Seals

A common option for weather, water, ozone and UV exposure. Final selection depends on operating conditions.

Custom-Cut Gaskets

Standard and non-standard shapes produced from drawings, CAD files, dimensions or samples.

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
