Sealants that transfer heat!

These sealants are valuable tools to have in your shop. They cure quickly to save you time between the repair and pressure-testing. And our sealants conduct heat, eliminating the complications of uneven heat transfer.

LHC724 works well with cast iron, steel, brass and stainless steel. LHC724 has a very low viscosity which lets the fluid flow into small pores and voids with vigorous capillary action. This provides extra insurance that your repair will pass pressure-testing the first time. Permanent dependable repairs are possible!

LHC623 is formulated to be used with aluminum, the installation of seats and guides in aluminum heads, and during the installation of locks in any material. LHC623 is slightly thicker than LHC724 because of an additive that prevents the aluminum from galling. You will appreciate the way this additive lubricates your press fit parts. You can eliminate freezing seats and heating heads before seat installation. Apply LHC623 and the seats can be driven into place. No magic, just good products.
  • Improve heat transfer by filling small voids with micron-sized, thermally-conductive particles
  • Improve stitching pin thread seal
  • Seal and retain valve seat inserts-improved heat transfer will increase valve and seat life
  • Seal and retain cylinder sleeves, bolt hole sleeves, injector tubes, water-cooled valve guides, freeze plugs or any other parts which require a positive seal and heat transfer
  • Easy to use one-part anaerobic cures in the absence of oxygen
  • Improved packaging: a better-balanced bottle plus an extension tube with LHC724 for dispensing one drop at a time
  • Air space in bottle prevents curing before you use the sealant.
