  • Single bolt design allows quick installation with basic tools

Repair Clamp for 1/2 Inch Pipe

The Zoro Select 45181 repair clamp is a stainless steel fitting designed to seal damaged sections of 1/2 inch pipe. It suits maintenance technicians and facility managers who need a quick, reliable fix without replacing the entire line. The single-bolt Redi-Clamp design allows fast deployment on water or air systems in commercial and industrial settings.

Pressure Rating Defines the Application

This clamp is rated for a maximum operating pressure of 150 psi and a maximum vacuum pressure of 150. That limit is the single specification that determines whether the clamp matches the system you are repairing. Exceeding 150 psi risks joint failure, so verify your line pressure before selecting this part.

Simple Bolt-Down Installation

Installation requires tightening the single steel bolt to compress the neoprene gasket against the pipe surface. The 3 inch overall length provides partial gasket coverage, so the damaged area must fall within that window. Clean the pipe thoroughly and ensure the bolt torque creates a uniform seal to prevent leaks at the edges.

Questions about this item

What does the 150 psi rating mean for a live water line?

The clamp is rated to seal against 150 psi internal pressure, so it will hold on typical municipal or well supply lines without leaking.

How does the single-bolt stainless clamp with a neoprene gasket actually seal the pipe?

Tightening the single steel bolt compresses the neoprene gasket against the pipe wall over a 3 in length, creating a partial-circumference seal rated for 150 psi and 180 °F.

Will this clamp fit onto a standard half-inch nominal pipe without extra fittings?

Yes, it is made for 1/2 in pipe size and the 3 in overall length spans the damaged section, so it clamps directly onto the existing pipe.
