4 in. Four-Bolt Repair Clamp

This 4 in. four-bolt repair clamp is built from 304 stainless steel for plumbing professionals and maintenance teams who need a durable pipe repair solution. It fits 4 in. pipe and tube sizes and carries a 150 psi maximum pressure rating. The clamp operates across a temperature range of -40 to 212 degrees F and includes nuts and washers for a complete assembly.

Verify pipe size and pressure before ordering

Confirm that the existing pipe or tube measures 4 in. so the clamp seats correctly on the line. Ensure the system working pressure does not exceed the 150 psi limit of this clamp. Check that the service temperature stays within the -40 to 212 degrees F range for reliable sealing performance.

Fits 4 in. lines with a 12 in. repair span

The clamp spans 12 in. along the pipe and uses 7/16 in. bolts to secure the joint, freeing installers from sourcing separate fasteners. Its 304 stainless construction resists corrosion in water and wastewater applications, and the metal-detectable body helps locate the repair during future inspections. The included nuts and washers simplify the installation kit.

Questions about this item

Does the 330-1112 clamp ship with all four bolts, nuts and washers, or must I source any hardware separately?

The clamp includes nuts and washers; the four 7/16 in. bolts are part of the assembly so no extra hardware is required.

Should I select the 4 in. size or a different diameter for a 4 in. pipe repair?

Choose the 4 in. model; it matches a 4 in. pipe and tube size and provides a 12 in. sealing length.

What does the 150 psi rating mean when the clamp is installed on a hot water line?

The clamp holds up to 150 psi across a temperature range of -40 °F to 212 °F, so it remains sealed on typical hot water lines.
