Pipe, Tubing, Hose, and Fittings

Stainless Steel Pipe and Pipe Fittings

Stainless steel has very good to excellent corrosion resistance.

Iron and Steel Pipe and Pipe Fittings

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

Brass and Bronze
Pipe and Pipe Fittings

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.

Titanium Threaded Pipe Fittings

Titanium Threaded Pipe Fittings

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.

Copper-Nickel Pipe and Pipe Fittings

Copper-Nickel Pipe and Pipe Fittings

Copper-nickel has excellent resistance to stress cracking and has better corrosion resistance than most stainless steel alloys. It can stand up to corrosive environments, such as salt water applications.

Pipe Repair Clamps

Pipe Repair Clamps

These clamps let you repair pinholes and cracks in plastic or metal pipe without having to dismantle your system.

Expansion Joints

Expansion Joints

These joints reduce stress, vibration, and noise in piping systems by providing a point of flexibility to absorb movement.

Hose and Hose Fittings

Tubing and Tube Fittings

Other Control of Liquids, Gases, and Solids

Pressure Test Fittings

Pressure Test Fittings

When you need to test pressure, these fittings create a temporary connection point so you can attach test gauges and other test equipment.

Pipeline Fluid Blockers

Also known as pipe blinds and paddle blinds, fluid blockers slip between two Class 150 flanges to temporarily stop flow so work can be performed downstream without draining the system.
