MJ FIELD LOK® Gaskets

U.S. Pipe's MJ FIELD LOK Gasket provides the joint restraint that typically requires concrete thrust blocks or lug-type restraints outside the joint. That means you'll have fewer installation steps, with faster and easier installations.

There's no learning curve either. Install it just like a standard mechanical joint gasket.
