Pipe and Pipe Fittings

Iron and Steel Pipe and Pipe Fittings

testString

Iron and steel are more economical than stainless steel. They are compatible and can be used interchangeably.

Stainless Steel Pipe and Pipe Fittings

testString

Stainless steel has very good to excellent corrosion resistance.

Brass and Bronze
Pipe and Pipe Fittings

testString

Brass and bronze have good corrosion resistance. They are often used in drinking water and plumbing applications. Brass and bronze are compatible and can be used interchangeably.

Aluminum Pipe and Pipe Fittings

testString

Aluminum has good corrosion resistance and is lightweight.

Titanium Threaded Pipe Fittings

testString

Titanium has similar strength to steel, but is approximately 40% lighter. It has better corrosion resistance than most stainless steel alloys and can handle corrosive substances, such as salt water and acids.

Plastic Pipe and Pipe Fittings

testString

Plastic pipe and pipe fittings are lighter in weight than metal pipe and pipe fittings. They are typically for low- to medium-pressure applications up to 1,000 psi.

Other Plugs

Compact Pressure-Relief Valves

testString

Less than a quarter of the height of standard pressure-relief valves, these are often installed on tanks in low-clearance areas.

Breather Vents

testString

Protect against excess vacuum and pressure in cylinders, gear boxes, enclosures, manifolds, and tanks.

Sights

See inside tanks, gear cases, bearing housings, and mixers.

Easy-Grip Drainage Valves

The large knob makes these drainage valves easy to grip.

Oil Fittings

Oil Fittings

Edge Seals

Edge Seals

Often found around doors, windows, and enclosures to prevent dust and water from entering or prevent heat from escaping.
