Chemola™ Desco TFE-Seal 108 is the ultimate sealant for damaged valves. It was developed and tested by a group of valve repair specialists with over 20 years combined experience. This is the ultimate sealant of internally worn or damaged valves. It contains a 100% synthetic base fluid for excellent resistance to washout from hydrocarbons. If TFE-Seal 108 won’t seal your valve, it will need to be taken offline or rebuilt.
Chemola™ Desco TFE-Seal may be used on worn or pitted valves. It can also be used as a sealant for stuffing boxes or as an injectable packing.
