Brand Hylomar

Hylomar Universal Blue is a non-setting gasket jointing compound for use on gaskets and machined metal joint faces in automotive and engineering applications.

Because it does not harden, it allows unlimited assembly time and permits differential thermal expansion of the mating components while maintaining a leak-free seal. It resists fuels, coolants and lubricants, withstands continuous temperatures up to 250°C, and is unaffected by vibration. Joints can be separated again easily for service.

Supplied in a 100g tube.

Frequently asked questions

What is Hylomar Universal Blue (RTC3347) used for?

Hylomar Universal Blue is a non-setting gasket jointing compound for machined metal joint faces throughout the engine, gearbox and drivetrain. Unlike RTV sealants it never fully hardens, keeping joints cleanly separable for future service. Supplied in a 100g tube.

Can Hylomar Universal Blue be used with an existing gasket?

Yes. Apply it thinly to either side of a gasket or directly between machined joint faces without a gasket. It fills minor surface irregularities and resists fuels, coolants and lubricants. Its non-setting nature means the joint can always be dismantled without damage.

What temperatures and conditions can Hylomar Universal Blue handle?

Hylomar Universal Blue withstands continuous temperatures up to 250°C, resists fuels, coolants and lubricants, and is unaffected by vibration. It's suitable for engine, gearbox, axle and drivetrain joints across the Defender, Discovery 1 and 2, Range Rover Classic, P38 and Freelander.
