DP Seals Ltd

DP Seals is a leading manufacturer and supplier of high precision custom seals, mouldings and gaskets for a diverse range of applications, from the well-known London underground ticket machines to applications involving Formula 1 racing cars and aerospace where our involvement includes products for Airbus and Dreamliner as well as the latest military fixed and rotary wing aircraft.

With over 40 years of experience, three manufacturing facilities and a team of fifty dedicated staff DP Seals is well equipped to take on some of the more demanding projects where others have failed.

This problem solving knowledge combined with our ability to specify formulas and compositions for materials has proved invaluable particularly where customised seals and mouldings are required for some of the more hazardous applications such as deep sea installations where fibre optic cable connectors are used for oil well logging equipment.

Kean Leong Choon, CEI Ltd

Shout out to Tina and the team who helps me out through tough times... Excellent business partner to work with... Excellent job

Mike Beale, Cresta Seals

My company has been directly involved with D.P. Seals Ltd since our inception in 1978. I would like to thank the Piper family for their continued support during this time. The company is innovative and the product unfailingly excellent. In the rapidly changing and often challenging industrial climate, it has been of great benefit to me personally to have been able to rely on their profound knowledge of rubber seal manufacture and supply.

Chris Bideau, Hope Technology Ltd.

Off-the-shelf seals and o-rings don’t always fit the bill, we often need custom components to meet specific needs, or polymer blends with very demanding characteristics. DP Seals not only delivers the highest quality backed with very sound engineering, its company ethos is very similar to our own
