Genuine Hylomar is perfect for sealing Hewland bearing carriers and rear covers, or any other parts that need to be disassembled easily and without a lot of scraping to clean up the residue. It is not recommended for semi-permanent assemblies such as Hewland sideplates. Seals gaps up to .010 inch and since it never hardens, it makes disassembly a snap. It cleans up easily with acetone, even after use. Hylomar also makes an excellent gasket dressing.
Hylomar is not affected by oil, gasoline, or glycol. It is oxygen-sensor safe and will not cause corrosion of any metal surface. Withstands operating temperatures up to 600° F. Supplied in 100 gram (3 ounce) tubes as a medium consistency paste. We also offer Solvent-Free Hylomar Advanced Formulation (AF) Liquid Sealant in 8 ounce brush-in-cap cans (Part No. 3318).
We also stock Wellseal (Part No. 3304), a similar sealant preferred by some engine builders.
