Previously known as TITE SEAL®, Abbey Product’s Niel Seal Medium Compound seals with a gasket or as a gasket. Seals pumps, tanks, pressed plates, covers, pans, etc. for pipe threads and imperfect or uneven surfaces. For general gasketing and machine joints, cylinder heads, manifolds, differentials, transmissions, muffler joints, radiator hose connections, and as a filler for water pump packing. Used as a gasket for housings that must retain oil and grease on appliances of all types.

Medium Compound (heavy paste consistency)

  • Heat-proof, vibration proof, non-solvent
  • Will not shrink, crumble, or crack
  • Prevents rust, corrosion, and seizure of joints, bolts, nuts, studs, and thread fittings
  • Withstands higher temperatures and pressures than other
  • Unaffected by water, gasoline, kerosene, grease, oil., LP and natural gas, steam, hot or cold water, glycerin, ethylene glycol ammonia, etc.

Light compound, also available, which is a medium paste consistency for most aircraft applications.  Used as a joint sealant, caulking compound, corrosive preventative, threaded joint dressing, insulating material, or filler with packing.

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.
