Experience has proven that periodic maintenance will make valves operate easier and seal properly. A small amount of the correct lubricant into the body or seat rings, fresh grease into the stem bearings, checking the stem packing and replenishing as necessary will add years, even decades to the service life of the valve.


Sealweld products have been developed over almost forty years of practicing on-line valve maintenance. We strive to make the valve technicians job more productive through the development of these effective products. We are constantly upgrading our sealant delivery systems by improving our pumps and adapters. Just as fuels such as gasoline have evolved over the years, so must our lubricant/sealants and delivery systems. New products are constantly being developed to meet the demanding needs of pipelines around the world.
