Gasgacinch Gasket Sealer remains flexible and makes it easier to assemble and disassemble the engine or transmission. Often any residue of Gasgacinch may be removed simply by rubbing it away. Many other sealers require solvents or destructive scraping to clean off a head or flange.

Gasgacinch adheres to carbon steel, alloy steel, aluminum, titanium, lead, magnesium, synthetic and natural rubber, copper and cork.

Gasket Sealer vs Competitor’s Thick and  Pasty Gasket Sealer



Gasgacinch Gasket Sealer may be used in hot, cold, wet, dry, acid, basic, and abrasive environments. Gasgacinch, when cured, is flexible, has high-peel strength, high-shear strength, fatigue resistant, vibration dampening, high heat resistance, gasoline resistant, and oil resistant.


Gasgacinch performs exceptional compared to other sealants that are pasty and thick. Competitor?s thick material makes it difficult to seep into the small imperfections of the metal surfaces, creating air pockets where leaks will develop. In contrast, Gasgacinch is very fluid, which allows it to flow into the small imperfections of metal surfaces (see right).


GASGACINCH includes heat-resistant formulated compounds and contains NO HEAT RETAINING metal powders. Because of its superior composition, GASGACINCH has the versatility for a broad range of applications not found in other sealants. GASGACINCH’s proven performance is preferred in nearly all mechanical industries including: auto repairdiesel and truck repairhigh-performance engine buildersmotorcycle repair and many more. GASGACINCH offers:

  • Superior grip as a belt dressing
  • Unmatched head gasket seal
  • Leak prevention on “high-leaking” vehicles
  • Increased protection for radiator-hose connections
