A specialist Aerospace unit

Our dedicated Aerospace unit provides unrivalled experience and expertise from design stage input, research, development and prototyping of components right through to manufacturing. Global military and civil avionics companies rely on our custom rubber aircraft seals, mouldings, glands and boots to operate in the harsh environments commonly experienced by fixed and rotary wing aircraft.

Our mouldings are produced to the highest levels of precision and quality with innovative and effective solutions. These cover a comprehensive range of applications from galley seals in the Airbus A380 to anti-vibration missile mounts on the Saab Gripen. Other aerospace gaskets and mouldings examples include:

Diaphragms
Rubber to metal bonded parts
Fire Shut-off Valve Seals
Check Valve Seals
Ball Valve Seals
Aerial Refuelling Transfer Pump Seals
Feed, Scavenge & Transfer Jet Pump Seals
Fuel Pump Seals
Aerospace O-rings
HTE Seals

We have particular expertise in rubber-to-metal bonding, producing complex components that play a vital role in fuel and hydraulic systems in both legacy and new aircraft. Specific metal parts, treatments such as anodising and conversions are all provided by our own Nadcap approved partners. This enables us to supply fully integrated rubber-metal components with complete traceability, assured quality and enhanced cost-effectiveness.

Rubber materials expertise

Developing custom aerospace rubber mouldings for demanding applications requires knowledge both of materials and environment. Working hand-in-hand with aerospace engineers DP Seals complies with the rigorous AS 9100 quality regimen in all aspects of its work. This includes providing advice on material blend selection, tool development, prototype mouldings to volume delivery of materials, ensuring that products meet specification.

Specially formulated rubber polymers can be developed to ensure high tensile strength, fuel/oil tolerance and effectiveness at low pressures and temperatures intrinsic to aerospace environments. And, to meet requests from engineering companies at the cutting edge of their technologies, we continuously investigate new compounds through our on-going R&D programme.

From nitriles, neoprenes and silicones through high-performance Viton Extreme and FFKM to cutting edge polymers like silicone perfluoroelastomer and nanotech rubbers, DP Seals uses its 40-year experience in rubber chemistry to work with compounders to develop the right blend for your application.

Phenolic Resin Mouldings for Aerospace

Thanks to the unique flexibility of our patented moulding system, DP Seals are able to produce complex and highly detailed mouldings using Phenolic Resins.
Phenolic Resin is a highly durable lightweight material used to make a wide range of products used extensively in the aerospace and defence industries. A combination of dielectric and mechanical strength, dimensional stability, heat and chemical resistance make it ideal for producing long lasting complex parts. Thanks to the nature of the material it can be moulded to tight tolerances for high-precision applications. Typical use would be in the aircraft interior where it is used widely but also in jet engines, rocket nozzles and missile defence systems.
