Hylomar M

The Original Universal Jointing Compound!


Hylomar M is a highly-engineered, polyester- urethane based non-setting and non-hardening gasketing compound. The compound is resistant to a wide range of fluids including industrial fuels, oils, water and brine, air, turbine and piston engine combustion products, water, water/glycol and methanol mixtures, petroleum and synthetic diester lubricating oils, gasoline and kerosene fluids (Avtur and Avcat) and fluorocarbon refrigerants. It can be used to seal both joint surfaces and threaded parts.

Instructions For Use:

The joint faces should be clean and dry. Both faces should then be coated with a thin even film of the product, and the solvent allowed to evaporate. The components can then be assembled. Since Hylomar M is non-setting, once applied to the faces of the component, immediate assembly is not required. Due to the nature of Hylomar M, re-torquing of assembled components may be required.

Typical Applications

Hylomar M enables the effective sealing of metal-to-metal and plastic-to-plastic components. Typical applications include water and oil pumps, instrument inspection covers, cylinder heads and sumps, coating pre-formed gaskets, weather proofing motors and outdoor high voltage circuit breakers inlet manifolds, timing case covers, oil pump joints, gear box and transmission components and thread sealing. It has also been successfully used in the assembly of gas turbines, water cooled generators and turbo vacuum systems. There is no staining of copper and silver, etc., from traces of volatiles at elevated temperature, and is therefore suitable for joints, and threads in close proximity to switch mechanisms. Hylomar M is harmless to joint materials. It is equally suitable for use as a gasket dressing and for metal- to-metal application.


  • Manufactured under license from Rolls Royce
  • Due to remaining elastic, the compound seals parts permanently even if they are under constant vibration for years
  • Strong adhesive properties. When drawn away from the surface, no fibers of the material are present. No dripping from vertical or downward facing surfaces
  • Temperature range from -58F to +482F
  • 50-state VOC complaint
  • Minor conduction of heat
  • Will not react with metal or other materials
  • Resistant to fuels, oils, coolants, and gases
  • Gap fill: 0.1 - 0.15mm
  • Easy to disassemble components
  • Use as a non-curing thread sealant
  • Use as a gasket dressing to improve the sealing performance of the gasket and to assist gasket alignment during assembly
