Product Information

Seal Master 1603 is a synthetic biodegradable high viscosity plug valve lubricant that will prevent valves from freezing. Because 1603 contains a special ingredient for lubricity it is especially effective in heavy duty applications. The versatility of Seal Master is unsurpassed since it can be used in a variety of applications in nearly all industrial applications. This product is unaffected by acids, harsh chemicals, and caustics and will not dissolve in the presence of aliphatic hydrocarbon. 1603 prevents scoring and galling on precision valves, keeps liquid or gas from escaping and is insoluble in water. Seal Master also combats corrosion and eliminates waste. The special formulation makes 1603 the ultimate solution for sealing valves carrying natural gas, crude oil (sweet or sour), water and condensates. 1603 resists H₂S and CO₂.

1603 is primarily used to keep valves free of freezing in all types of industrial areas. Aliphatic hydrocarbons and aqueous solutions is where 1603 is recommended. This product should not be used for steam service or with hydrogen peroxide or sulfuric acid. This product is available in weight of 5 gal - 40 lbs. and 55 gal - 400 lbs.
