CheckSeal™ 38P
Non Curing Sealant
Check Seal™ 38P is a sealant compound containing TFE-fluorocarbon particles blended into a synthetic binder. It can be either pre-formed manually or pumped into place with a high pressure (10,000 psi) grease gun. 38P is chemically stable and resistant to most chemicals over a wide pH range. It is a highly versatile and durable self molding sealant used for stuffing boxes and for all types of valves, pumps and mechanical equipment.
