PLCS Medium Pressure Encapsulation

Encapsulation works by encasing the leaking joint in a mold, filling the mold with a two-part polyurethane sealant and pressurizing it to above mains pressure by twisting down the mold neck. This action stops the leak, as gas cannot leak from low pressure to a higher pressure.

Medium Pressure fabric molds are made from very high strength, non-stretch fabric.
They are pressurized by twisting the necks down with an unbreakable fiberglass rod.
A vent is often installed to remove trapped gas.
A gauge records sealant pressure to make sure that it overcomes mains pressure, which can be up to 25psi.
The sealant cures to a tough, flexible synthetic rubber that is permanently adhered to the pipe joint.
Encapsulated joints are sealed for the lifetime of the pipe. They will never leak again.
Stock kits are available for most standard joints and couplings.
Almost any type of joint or fitting can be encapsulated with a custom made special kit.
Re-usable metal molds can be fabricated to encapsulate joints and fittings working at up to 60psi
