Even the finest caliber hydraulic gasket can leak when it's under enough pressure, so it is important to use the right sealant to prevent fluid seepage. D & M Hydraulic Sales & Service, the premier supplier of hydraulic gaskets in Waipahu, HI, offers some effective sealing solutions to keep hydraulic fluid where you want it.

Low-Pressure & Low-Temperature Sealants

When you're dealing with a paper or cardboard gasket in an environment around 300 degrees, shellac is a good choice. It stands up to most engine fluids and is ideal for use with differential cover and timing cover gaskets. Three types of Form-A-Gasket® sealers (fast drying, slow drying, and brushable) can handle temps of up to 400 degrees. The last two are non-hardening, so they are easier to apply and their cleanup is much simpler.  

High-Temperature Sealants

Gaskets in Waipahu, HIHigh Tack™ sealant is non-drying and similar to shellac, but it has a heat rating of 500 degrees. Copper gasket sealant can sustain similar temperatures, and its metal content helps mated surfaces transfer heat evenly, so it is suitable for exhaust manifold and cylinder head gaskets. Hylomar is a tacky, non-hardening polyurethane compound that makes disassembly and reassembly convenient. It is likewise rated for 500 degrees.

Extreme Temperatures Sealants

For extreme temperatures, RTV silicone sealants are a good choice. They can withstand 650 to 750 degrees, depending on the product. They are easy to apply and come in squeeze tubes, caulk gun-style tubes, and aerosol cans.
