Inflow Seal manhole cover sealing system

The manhole cover sealing system from Inflow Seal is a vertical rubber gasket that installs on the casting to seal out inflow. The EPDM seal is designed with internal hollow voids to enable the material to contract yet apply a sealing force against the cover’s vertical side. The rubber comes in a long continuous run and is cut to length to fit the size of the manhole casting opening. The seal is attached to the casting using a marine-grade adhesive/sealant. Silicone grease is applied to protect the seal, lubricate and enhance the water sealing capabilities. The system is capable of sealing up to 3 feet of water depth. 800-490-5325; www.inflowseal.com.
