Matco-Norca 330-0412 Repair Clamp 3/4" Pipe 12"L

12-inch stainless-steel repair clamp for 3/4-inch

This clamp wraps a 3/4-inch pipe with a 12-inch stainless-steel band rated to 150 psi. The Grade 304 stainless band and four steel bolts seal a nitrile-rubber gasket rated to 212 degrees Fahrenheit. It handles aromatic hydrocarbons, gasoline, mineral oils, natural gas, petroleum oils and vegetable oils. Installers repairing pressurised lines in the listed fluids will find the length and pressure rating match common service requirements.

Verify pipe size fluid compatibility

Measure the outside diameter to confirm a 3/4-inch nominal pipe size because the clamp is sized for that dimension only. Check that the fluid in the line appears on the approved list: aromatic hydrocarbons, gasoline, mineral oils, natural gas, petroleum oils or vegetable oils. Ensure the operating pressure stays at or below 150 psi and the temperature does not exceed 212 degrees Fahrenheit. Confirm at least 12 inches of straight pipe is accessible for the partial-coverage gasket and four-bolt pattern.

Clamp seals the leak and restores service without

The 12-inch band bridges the damaged section so the line stays in place while the nitrile gasket seals against the pipe surface. Four steel bolts draw the Grade 304 stainless band evenly across the partial-coverage gasket. No welding or pipe replacement is required, freeing the crew from hot-work permits and pipe-threading tools. The clamp works on the listed fluids at up to 150 psi and 212 degrees Fahrenheit, returning the system to service quickly.
