One of the founding members of our company worked on the first pressure hull glands for submarines in the 1950s and we have been expertly associated with them ever since.

Pressure hull glands have to be a specific mix of durability and reliability, adhering to incredibly strict tolerances and specifications as these penetrate the hull of the vessel and have to endure high pressures over continued dives and rapid ascents. We have held the Capability Approval on these from the MoD for nearly 20 years continuously and we know of no other company worldwide who can make that statement.

submarineOur “fit and forget” products have been in service for 25 years with zero leaks as evidence from the Royal Navy shows.  This is founded on thermoplastic moulding technology where the moulding is pressure injected at temperature and fully amalgamates to the cable jacket and chemically bonds to the gland stem.

The cost of rectification for any of these products that fail significantly outweighs the upfront cost so you need to know that the systems will not fail and that’s what we can promise with our 100% record and zero leaks across 10,000 installations.
