Three-bolt stainless repair clamp
The Matco-Norca 330-109 is a three-bolt repair clamp built from 304 stainless steel for 3-inch pipe. It uses a nitrile rubber gasket with partial coverage to seal leaks on aromatic hydrocarbons, gasoline, mineral oils, natural gas, petroleum oils and vegetable oils. The clamp handles 150 psi operating pressure and 150 vacuum pressure at temperatures up to 212 degrees Fahrenheit. Its nine-inch overall length provides a solid repair span.
150 psi pressure rating
The single specification that decides fit is the 150 psi maximum operating pressure combined with the 150 vacuum rating. Systems that run higher pressures or deeper vacuums will exceed the clamp's design limits and require a different sealing method. The 304 stainless body and nitrile gasket are compatible with the listed fluid types at the stated temperature ceiling. Verify your line pressure before installing.
Suits standard 3-inch pipe repairs
This clamp suits maintenance teams and plumbers fixing 3-inch lines carrying the approved fluids within the rated pressure and temperature range. It is not for buyers who need full-circumference gasket coverage or higher pressure ratings. It is not for lines carrying fluids outside the listed compatibility group or operating above 212 degrees Fahrenheit.

Questions about this item
How does the 150 psi pressure rating hold up when the clamp is actually installed on a 3 in pipe?
The clamp is rated for 150 psi maximum operating pressure and 150 maximum vacuum pressure, so it will maintain that seal on a 3 in pipe as long as the bolts are torqued correctly and the nitrile gasket is seated evenly.
What does the three-bolt 304 stainless design limit in real use?
Three bolts give even clamping force around the 9 in length, and the 304 stainless band resists corrosion from gasoline, mineral oils, natural gas, petroleum oils, vegetable oils and aromatic hydrocarbons up to 212 °F.
What clearance and bolt pattern do I need to fit this 9 in clamp on the pipe?
The clamp spans 9 in overall with three steel bolts spaced along the band; allow enough room around the 3 in pipe for the bolt heads and a wrench to tighten them without obstruction.
