At Darwen Diesels we stock the highest quality, non-setting gasket and jointing compound available in the UK. It was designed and manufactured under licence from Rolls-Royce, where it was used for sealing aircraft engines. Hylomar continues to manufacture Rolls-Royce approved products for sealing aeronautical turbines and flanges.

Hylomar Aerograde gasket and jointing compound has a wide operating temperature range (-50°C to +250°C) is fuel resistant and Dichloromethane free, as specified by OEMs around the world for use on gaskets and metal surfaces.

It is widely regarded as the world’s leading gasket and sealing compound. It is used in compressors, engines, heavy equipment applications and by OEM manufacturers worldwide. It is the sealant of choice in many world-class racing teams.

The specialised polymer formulation is known to be highly effective as a sealant in applications where extreme vibration, distortion, or joint movement is expected.

It can be used to replace a traditional gasket or to “dress” it in order to greatly improve a gasket’s performance. It is non-hardening and manufactured by Hylomar Limited and the product is called Blue Hylomar or Aerograde, which reflects its status as the gasket compound used widely in defence and Aero industries worldwide.

Hylomar Aerograde gasket and jointing compound is available in 100g and 40g tubes and is in stock and available for next day dispatch.
