Marine Hatch Seals and Gaskets

Featured Materials


Our experience in manufacturing inflatable seals along with our unique molding technologies are well suited for the high performance requirements ofcommercial and military programs. These applications include a number of highly-customized naval and submarine sealing systems. Applications for our products include inflatable seals for sliding windows on Coast Guard vessels, large inflatable seals used for the aft deck ramp on Navy destroyers, and special inflatable butterfly valve seals used on Navy ships.

Aft Deck Inflatable Door Seals

We manufacture Type 1 inflatable seals using weather resistant EPDM rubber and silicone compounds. This seal is ideal for weathertight sliding doors and hatches exposed to the elements. Locations for these seals include patio doors, sundecks, aft-deck doors, and other leisure areas.

Inflatable Seals for Sliding Hatch Covers

Large sliding hatches are particularly difficult to seal using traditional means. An inflatable, marine-hatch seal, however, still works within a wide tolerance range and pulls back from the door to allow for free sliding motion.

Deck Elevator Inflatable Seal

Type 1 fabric-reinforced inflatable seals provide an excellent solution to requirements for watertight sealing between cargo elevator platforms or cargo hatches and surrounding decks on commercial and naval cargo carriers. A leak-tight seal is maintained even under conditions of severe racking caused by sea loads on the hull. If required, these seals can be supplied in an oil and fuel resistant neoprene or nitrile material.

Inflatable Seals for Marine Hatches

Type 1 fabric-reinforced inflatable seals may be used with large, hinged marine hatches to ensure a leak-tight seal and compensate for any tolerance variation between the cover and the hull of the ship. If required, the seals can be supplied in an oil and fuel resistant neoprene or nitrile material.

Submarine Periscope Housing

The periscope cable assembly is made of two parts which are bonded together to form the final housing. The extrusion is flexible to allow for movement as the periscope is operational, and consists of multiple channels (lumens) where electric cables are snaked through.
