Low-Pressure Clamp-On Connectors for Water
Also known as no-hub couplings, these have a one-piece sleeve with a stop in the center, so you know your pipe is always aligned correctly. Tighten the bands to form a strong seal on rigid pipe of the same or different materials. Connectors are 304 stainless steel for good corrosion resistance.
Note: Copper tube size is the accepted designation of the copper tubing industry, not the actual OD.

Low-Pressure Clamp-On Connectors for Air
- For Use With: Air
- Temperature Range:
Neoprene Rubber Gasket: -20° to 190° F
Silicone Rubber Gasket: -100° to 500° F - For Pipe Material: Stainless Steel, Iron, Steel, Aluminum, Copper, PVC Plastic, CPVC Plastic
Tighten the bolts on these connectors to join two pieces of rigid pipe of the same or different materials. They are for use in low-pressure air and vacuum conveying systems, as well as in gravity-flow systems. Connectors have a stainless steel strip that provides an escape route for electrostatic buildup when used in a fully grounded system.
Connectors with sleeve have an inner lining that protects the gasket.
