Steel Pipe Fittings

Steel pipe fittings carry the highest pressure at the lowest cost. Plated carbon steel is strong and economical, which makes it a smart pick for high-PSI discharge lines where chemicals are not a concern.

How to Choose

Match the thread size and type, then choose the shape you need, such as an elbow, tee, nipple, coupler, or bushing. Steel is best for plain high-pressure water. For chemical or saltwater service, choose stainless steel instead, since steel can rust. Confirm each fitting is rated at or above your machine's maximum PSI.

Common Applications

• High-pressure pump discharge plumbing
• Manifold and unloader builds
• Heavy-duty industrial setups
• Cost-sensitive plain water lines

Frequently Asked Questions

Why choose steel over brass?
Steel carries higher pressure and costs less. The trade-off is corrosion resistance, so steel is best on plain water lines, not chemical lines.

Will steel fittings rust?
Plated steel resists rust well in normal use, but chemicals and salt will corrode it over time. For those jobs, use stainless steel.

Do I need thread sealant?
Yes. Use thread sealant tape or paste on tapered pipe threads for a leak-free joint.
