Hylomar Universal Blue Sealant

Seal joints and improve gasket performance with Hylomar Universal Blue Non-Setting Gasket Sealant. Originally developed by Rolls-Royce’s Aerospace Division for jet turbine engine applications, this polyester-urethane-based sealant is designed to provide reliable sealing without hardening. Its non-setting formula remains permanently plastic within the specified operating conditions, allowing flexibility during assembly and making future disassembly easier.

Hylomar Universal Blue can be used as a gasket dressing or to seal compatible flanges with or without a gasket. It fills small surface imperfections on mating components and helps accommodate vibration and thermal expansion. Resistant to a wide range of fuels, oils, and other fluids, it is suitable for automotive, motorsport, industrial, and mechanical applications.
