Extreme-Pressure Iron and Steel Threaded Pipe Fittings

The strongest steel fittings we offer. They handle extreme-pressure applications, such as hydraulic, steam, oil, and natural gas systems.

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.

Straight Connectors

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

Zinc-Plated Steel—Zinc-plated steel fittings have better corrosion resistance than plain steel fittings.

Precision Extreme-Pressure Galvanized Iron and Steel Threaded Pipe Fittings

Made to tighter tolerances than other steel pipe fittings, these are also known as instrumentation fittings. They’re strong enough to handle extreme pressures, yet small enough to fit into cramped spaces. The galvanized finish protects fittings from rust in wet and outdoor environments.

High-Pressure Iron and Steel Threaded Pipe Fittings

Connect pipe in high-pressure systems. These iron or steel fittings are best for 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.
