The gold standard for push-on joint restraint. U.S. Pipe’s FIELD LOK 350^® Gasket is an extremely successful, trouble-free means of joint restraint in 4″ – 24″ sizes for well over one million Ductile Iron pipe and fitting joint assemblies across North America.

No pipe surface preparation or grooving is required for field cut pipe other than the cut end needing to be beveled as required for any push-on joint spigot end. Joints are restrained without thrust blocks, bolts, grooves, rods, clamps or retainer glands, resulting in savings of labor, material and time.
Available in 4″ – 24″ sizes (350 psi).

For sizes larger than 24″ see HDSS^® or HP LOK^® restrained joint products section.
