Clamp-On Connectors

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.

Low-Pressure Clamp-On Connectors for Air

These connectors are for use in low-pressure air and vacuum conveying systems, as well as in gravity-flow systems.

Low-Pressure Clamp-On Connectors
for Drain, Waste, and Vent

Cut-to-Length Low-Pressure Clamp-On
Connectors for Drain, Waste, and Vent

Connect two pipes that are up to 100 feet apart—cut the connector to the length you need and attach a clamp to each end.

Low-Pressure Quick-Lock Clamp-On Connectors for Air

A turn of the T-handle will tighten and loosen these connectors, so you can quickly disassemble and reassemble your lines without tools.

Medium-Pressure Clamp-On Connectors

Use in medium-pressure applications up to 230 psi.

High-Pressure Clamp-On Connectors

Use in high-pressure applications up to 500 psi.

Iron and Steel Pipe and Pipe Fittings

High-Pressure Socket-Connect
Steel Unthreaded Pipe Fittings

Socket-connect fittings are easier to weld than butt-weld fittings because the fitting doesn't need to align perfectly to the pipe. Slide the pipe into the socket and weld.

Thick-Wall Butt-Weld Steel Unthreaded Pipe Fittings

Butt-weld fittings allow for a smooth, flush connection that provides maximum flow.

Grooved-End Iron Pipe Fittings

The grooved ends on these iron fittings connect to pipe with a clamp to easily install piping systems.

Low-Pressure Iron and Steel Threaded Pipe Fittings

Use these fittings for low-pressure applications in noncorrosive environments.

High-Pressure Iron and Steel Threaded Pipe Fittings

These fittings can stand up to high-pressure applications. Use them in noncorrosive environments.

Plastic Pipe and Pipe Fittings

Clamps for Easy-Access UV-Resistant
Polypropylene Pipe Fittings for Chemicals

Use these clamps to connect easy-access UV-resistant polypropylene pipe fittings to pipe. The clamp-together design allows you to access your line for routine maintenance.

Clamps for Easy-Access CPVC
Pipe Fittings for Chemicals

Use these clamps to connect easy-access CPVC pipe fittings and pipe.

Thick-Wall Plastic Pipe Fittings for Water

Connect these fittings to thick-wall plastic pipe—they have thicker, stronger walls than standard-wall fittings, so they can handle heavy duty industrial plumbing and water supply applications, such as water processing, waste water treatment, and irrigation. They can withstand pressures up to 900 psi.

Standard-Wall Plastic Pipe Fittings for Water

Connect these fittings to Schedule 40 plastic pipe—they are the industry standard for residential and commercial low-pressure plumbing and water supply applications. They are plastic for good corrosion resistance.

Tube Fittings for Metal Tubing

Quick-Clamp High-Vacuum
Fittings for Stainless Steel Tubing

Also known as KF, QF, and NW fittings, these fittings are for high-vacuum applications, such as vacuum coating and heat treating, leak testing, and analyzing gases.

Vacuum Fittings for Steel Tubing

Use these fittings in an air vacuum system to avoid the hassle of brazing and welding. Insert two fittings into a clamp and tighten to form a secure seal in steel tubing.

Plastic Quick-Clamp Sanitary
Fittings for Stainless Steel Tubing

Clamps for Claw-Clamp High-Vacuum
Fittings for Stainless Steel Tubing

Connect claw-clamp high-vacuum fittings for an airtight seal.

Structural Framing

Heavy Duty Clamp-On Framing and Fittings

Thick construction makes this framing strong and sturdy.

Clamp-On Framing and Fittings

Fittings come in two pieces to wrap around rails, so you can quickly modify existing structures without disassembling. Use clamp-on framing and fittings to form temporary partitions, modular conveyors, and workstations.

Aluminum Slip-On Framing and Fittings

Half the weight of steel, this aluminum framing resists corrosion in wet environments.

Carbon Fiber Slip-On Framing and Fittings

Stronger than plastic and aluminum, this is the lightest weight framing we offer. It has good resistance to chemicals and salt water.

Galvanized Iron and Steel Slip-On Framing and Fittings

To provide corrosion resistance in wet environments, this framing is galvanized.
