About Backflow-Prevention Valves

For Use With: Water
Temperature Range: -50° to 180° F
For Pipe Material: Stainless Steel, Iron, Steel, Aluminum, PVC Plastic, CPVC Plastic

Use these clamps to repair pinholes and cracks in low-pressure water applications. Clamps are 304 stainless steel for very good corrosion resistance. They have a metal strip that bridges the opening between the bolts to provide complete coverage.

Low-Pressure Pipe Repair Clamps for Drinking Water

3" and 6" Lg.

7 ½", 12 ½", and 15" Lg.

For Use With: Drinking Water
Temperature Range: -20° to 180° F
Specifications Met: NSF/ANSI 61
For Pipe Material:
3"-6" lengths: Steel, PVC Plastic, Copper
7 1/2-15" lengths: Stainless Steel, Aluminum, PVC Plastic, Copper

Since they meet NSF/ANSI 61 safety standards, use these clamps to repair pinholes, cracks, and full-circle breaks in low-pressure drinking water applications. Clamps are 304 stainless steel for very good corrosion resistance. They can be used underwater and anywhere corrosion is a concern. They slip over your pipe, so there's no need to disassemble your system.

7 ½", 12 ½", and 15" long clamps are adjustable to accommodate slight variance of pipe OD due to aging or corrosion build up.

Low-Pressure Pipe Repair Clamps for Natural Gas

For Use With: Natural Gas
Temperature Range: -20° to 180° F
For Pipe Material: Iron, Steel

Use these clamps to repair pinholes, cracks, and full-circle breaks in low-pressure natural gas applications. Clamps are 304 stainless steel for very good corrosion resistance. They slip over your pipe, so there's no need to disassemble your system. Clamps are adjustable to accommodate slight variance of pipe OD due to aging or corrosion build up.

Deep-Freeze Pipeline Fluid Blocking Kits

Kits

Create a temporary ice plug in your pipe to make repairs without draining the line. Often used with sprinkler systems, these kits freeze the standing liquid in your line, eliminating the need to refill or reheat and preventing air-lock problems. Use them with pipes that run water or other fluid with a similar freezing point.

Wrap the included jacket around your pipe at an upstream location near the point of repair and inject CO2 (not included) into the jacket. After use, the CO2 evaporates and the ice plug melts, minimizing clean up.
