## Overview

Gasgacinch 440-B is a premium 8 oz gasket sealer and belt dressing trusted across automotive and mechanical industries.

Designed for easy assembly and residue-free disassembly, it outperforms thick competitors by penetrating micro-imperfections for a durable, long-lasting seal.

## Description

Gasgacinch Gasket Sealer and Belt Dressing provides unmatched gasket sealing properties, preventing leaks, reducing expensive repairs, and creates a superior grip as a belt dressing. 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. 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. 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 repair, diesel and truck repair, high-performance engine builders, motorcycle repair and many more.

Review: Gasgacinch - This stuff is top notch, it really does work for a variety of applications.
Review: Great Stuff - I've been using this stuff since 1978 when I rebuilt my first VW engine. There it is used as a sealer between the alloy case halves of the VW engine, but I use it also as a gasket dressing on carbs, water pumps, etc. I put a thin film on both gasket sides and it will not only hold them in place during assembly, but also provide a superior seal. Also, if you have to disassemble something down the road, the gasket can most times be saved and reused.

## Questions & Answers

**Q: Can I apply this around the edge and bolts of the oil pan? Will it fix the leak?**
A: I would try and replace the pan gasket first

**Q: How do you use this product as a belt dressing? Do you apply it with the belt moving or stationary on the engine?**
A: Having used this to seal gaskets (and for this use it is fantastic, no leaks but easy to remove later), I do not recommend using it as belt dressing; it gums up like rubber cement.

**Q: Anyone ever use this to glue Rubber Knee Pads to a Motorcycle Gas Tank?  Results??**
A: Not that I know of and I don't think it would be the best product for something like that. I'd recommend Barge Cement or Aquaseal.

**Q: I have a carburetor that won’t seal anymore. Can I use this to coat my gasket or saturate it in this? Will it fix the seal**
A: chances are there is a bigger problem than just needing "gasket seal"  without looking at you car i would not be able to repair it just by a simple comment,  if both areas are flat {the manifold and the carburetor} you actually would not even need a sealant.    i have been a diesel mechanic  for 40 years , this is one of the best products i have used { for 40 years} i am glad i can still find it.  i put a coat on the gasket and a coat on the part let semi dry {tacky} then put the gasket on the part and assemble.
