Rotating Joints

Aluminum One-Way-Flow Rotating Joints

Joints are aluminum, which is lighter than other metals.

Iron and Steel One-Way-Flow Rotating Joints

Joints are for one-way flow and are meant to be used in pairs—one joint serves as the supply line while the other serves as the return line.

High-Temperature Iron and Steel
One-Way-Flow Rotating Joints

Use these rotating joints to transfer high-temperature materials from your supply line.

Stainless Steel One-Way-Flow Rotating Joints

Joints are for one-way flow and are stainless steel for excellent resistance to corrosion caused by fluid flowing through them.

Brass One-Way-Flow Rotating Joints

Joints are for one-way flow and are brass for good corrosion resistance.

Brass Two-Way-Flow Rotating Joints

Joints are for two-way flow and are brass for good corrosion resistance.

Stainless Steel Two-Way-Flow Rotating Joints

Joints are for two-way flow and are stainless steel for excellent resistance to corrosion caused by fluid flowing through them.

Iron Two-Way-Flow Rotating Joints

Joints are for two-way flow and are meant to be used when you need the supply line and the return line to be on the same side of your equipment.

Rotating Joint Manifolds

Supply air to two different rotating objects from a stationary supply.

Metal Pipe and Pipe Fittings

Compact Extreme-Pressure
Steel Threaded Pipe Fittings

These fittings are strong enough to handle extreme pressures, yet small enough to fit into cramped spaces.

Extreme-Pressure Steel Threaded Pipe Fittings

The strongest steel fittings we offer, these can withstand extreme-pressure applications.

Medium-Pressure Iron and Steel Threaded Pipe Fittings

For use in noncorrosive environments, these fittings have better strength than our low-pressure iron and steel pipe fittings.

High-Pressure Iron and Steel Threaded Pipe Fittings

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

Extreme-Pressure Brass Threaded Pipe Fittings

Extreme pressures are no problem for these heavy-duty brass fittings.

Medium-Pressure Brass and
Bronze Threaded Pipe Fittings

Choose these fittings when you need better strength than our low-pressure brass and bronze pipe fittings.

Miniature Low-Pressure Brass Threaded Pipe Fittings

Less than an inch in length, these miniature fittings work well in low-pressure pipe lines that are tight on space.

Medium-Pressure Stainless
Steel Threaded Pipe Fittings

Choose these fittings when you want the same high-quality found in our low-pressure pipe fittings, but need more strength to handle higher pressures.

High-Pressure Stainless Steel Threaded Pipe Fittings

Use these heavy duty, corrosion-resistant fittings in high-pressure flow applications.

Low-Pressure Aluminum Threaded Pipe Fittings

In addition to being lightweight, these aluminum fittings offer good corrosion resistance. Use them in low-pressure flow applications.

Plastic Pipe and Pipe Fittings

UV-Resistant Polypropylene Pipe Fittings for Chemicals

Made of polypropylene, these fittings won’t deteriorate when exposed to the damaging effects of ultraviolet light and are suitable to use outdoors. They have the chemical resistance to withstand acids, solvents, and other harsh substances.

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.
