Extreme-Pressure Iron and Steel Threaded Pipe Fittings

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

Note: The maximum pressure listed for Class 6000 fittings is for conditions where there are no sudden changes in pressure or velocity. Please refer to ASME B16.11 to determine the specific maximum operating pressure for your application.

Precision Extreme-Pressure Stainless Steel Threaded Pipe Fittings

Made to tighter tolerances than other stainless steel pipe fittings, these are also known as instrumentation fittings. The male threads are rolled for extra strength in extreme-pressure applications. Fittings are commonly used to connect equipment in gas and hydraulic fluid lines.

High-Pressure Iron and Steel Threaded Pipe Fittings

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

Note: The maximum pressure listed for Class 3000 fittings is for conditions where there are no sudden changes in pressure or velocity. Please refer to ASME B16.11 to determine the specific maximum operating pressure for your application.

Standard-Wall Brass and Bronze Threaded Pipe Nipples and Pipe

Also known as Schedule 40, this pipe is for use in low-pressure flow applications. It is brass, which offers good corrosion resistance.

Pipe Adapters—Fully Threaded

Male

Fully threaded pipe is also known as a close nipple; it is threaded on each end to the center.

Seamless—Pipe has a smooth interior for unrestricted flow and is stronger than welded pipe.

NSF/ANSI 61—To adhere to safety standards for drinking water systems, use pipe that meets NSF/ANSI 61.

Universal-Thread Medium-Pressure Brass and Bronze Threaded Pipe Fittings

When you're unsure of the exact thread type you need, these fittings have universal threads that are compatible with the most common ones (NPT, NPTF, BSPP, BSPT). Made of nickel-plated brass, they resist corrosion better than plain brass fittings. A reusable Buna-N O-ring protects against leaks. Connectors, adapters, and reducers all have a hex-shaped body, so you can tighten them with a wrench.

Intermittent-Swivel Straight Reducers

Male x

Universal

Fittings with intermittent swivel rotate 360° as needed to allow movement in a rigid metal piping system.

NPTF Thread—NPTF (Dryseal) threads are compatible with NPT threads.

Nickel-Plated Brass—Nickel-plated brass pipe provides better corrosion resistance than unplated brass.
