Product Description

Niel Seal Gasket and Joint Compound

Previously known as TITE SEAL®, Abbey Product’s Niel Seal Light Compound is a flexible compound used as a joint sealant, caulking compound, corrosive preventative, threaded joint dressing, insulating material, or filler with packing. Used on manifold gaskets of automotive and aircraft engines, water heater fittings gaskets, gas range values and fittings, pipe threads, etc. For all metal-to-metal unions with any kind of gasket. The best product for silk thread joints.

Light Compound (medium paste consistency for most aircraft applications)

  • Unaffected by water, oil, gasoline, glycerin, steam, gas vapor, exhaust fumes, and most hard-to-hold liquids
  • Withstands higher temperatures than other brands
  • Will not harden – great for silk thread joints, gaskets, and pipe joints
  • Vibration-proof and easy to disassemble for repairs and adjustments
  • Prevents corrosion and seizing of metal parts
  • Expands and contracts without affecting seal

Medium compound, also available, which is a heavy paste consistency.  Seals pumps, tanks, pressed plates, covers, pans, etc. for pipe threads and imperfect or uneven surfaces.

Installation Tip:

Rub a light film on gaskets or mating surfaces for a dependable seal and easy removal. For pipe joints, do not apply to the first thread.
