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.

Low-Pressure Clamp-On Connectors for Drain, Waste, and Vent
To make installing and maintaining systems easy, these connectors come with clamps that form a strong seal on pipe and fittings once tightened.
Straight offset reducers connect one pipe to a smaller-diameter pipe, keeping your pipes aligned for obstruction-free flow in either direction. They are also known as eccentric reducers.
Pipe end-to-socket end connectors connect a pipe to a socket-end (female) fitting.
Connectors with a stainless steel sleeve reinforce the connection to increase shear strength.

High-Pressure Pipe Repair Clamps
These clamps have the highest pressure rating of all the repair clamps we offer. Also known as patch clamps, all have a partial-coverage gasket for use on pinhole leaks and small cracks. This gasket wraps around as much as 40% of the pipe. You’ll need to line the gasket up so it completely covers your pipe’s damaged area. Choose a clamp that’s long enough to cover your damaged area and at least 1” on both sides.
To make installation easy, all have a two-piece design. Position the two clamp halves over the damaged pipe and secure the bolts—there's no need to disassemble your system.
Fluoroelastomer gaskets resist most chemicals. They can be used in steam and other high-temperature applications.
4" long clamps are designed to repair small holes caused by pitting. 8" long clamps are designed to repair corrosion spots and splits.
