1-inch 304 stainless repair clamp

The Matco-Norca 330-059 is a three-bolt repair clamp designed for 1-inch pipe. Its 304 stainless steel body and nitrile rubber gasket handle aromatic hydrocarbons, gasoline, mineral oils, natural gas and vegetable oils. It is built for new installations or emergency repairs on compatible fluid lines.

Three-bolt design and partial gasket coverage

The clamp spans 9 inches overall and uses three steel bolts to secure a partial-coverage gasket against the pipe. This arrangement distributes clamping force while leaving space for adjacent fittings. No special tools beyond standard wrenches are required to tighten the bolts to spec.

Rated for 150 psi and 212 °F sustained service

Under continuous pressure the clamp holds 150 psi at temperatures up to 212 degrees Fahrenheit. The 304 stainless construction resists corrosion from the listed fluids during extended exposure. The nitrile gasket maintains its seal through thermal cycling without hardening or cracking.

Questions about this item

Will the 150 psi pressure rating hold during continuous service?

The clamp is rated for a maximum operating pressure of 150 psi and a maximum vacuum pressure of 150, so it is designed to maintain that limit under sustained use.

How much heat can the nitrile gasket take when the line runs all day?

The nitrile rubber gasket is rated to a maximum operating temperature of 212 degrees F, which is its limit during continuous operation.

What pipe size must I already have for this 330-059 clamp to fit?

This repair clamp is made for a 1 in pipe size and has an overall length of 9 in, so the existing pipe must match that diameter.
