Metal Pipe and Pipe Fittings

Low-Pressure Stainless Steel Threaded Pipe Fittings

testString

Use these corrosion-resistant fittings in a low-pressure pipe line.

Extreme-Pressure Stainless
Steel Threaded Pipe Fittings

testString

Use these fittings in extreme-pressure conditions up to 15,000 psi.

Low-Pressure Galvanized Iron
and Steel Threaded Pipe Fittings

testString

The galvanized finish on these fittings provides fair corrosion resistance. Fittings are for use in low-pressure applications.

Low-Pressure Iron and Steel Threaded Pipe Fittings

testString

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

Extreme-Pressure Steel Threaded Pipe Fittings

testString

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

High-Pressure Brass Threaded Pipe Fittings

testString

These brass fittings have the strength to handle high-pressure applications.

Low-Pressure Brass and
Bronze Threaded Pipe Fittings

testString

Use these fittings in low-pressure flow applications. They have good corrosion resistance.

Low-Pressure Plated Brass Threaded Pipe Fittings

testString

Used in low-pressure pipe lines, these brass fittings have a plating that makes them shiny and improves corrosion resistance.

Low-Pressure Aluminum Threaded Pipe Fittings

testString

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