High-Pressure Galvanized Steel Threaded Pipe Fittings
A galvanized finish gives these fittings better corrosion resistance than our plain steel high-pressure fittings. Also known as Class 3000 fittings, they have excellent strength to handle high-pressure applications.

Compact Extreme-Pressure Steel Threaded Pipe Fittings
These fittings are strong enough to handle extreme pressures, yet small enough to fit into cramped spaces. They are galvanized steel, which has fair corrosion resistance.
NPTF (Dryseal) threads are compatible with NPT threads.

Compact Precision Extreme-Pressure
Steel Threaded Pipe Fittings
Made to tighter tolerances than other steel pipe fittings, these are also known as instrumentation fittings. They are strong enough to handle extreme pressures, yet small enough to fit into cramped spaces. They are galvanized steel, which has fair corrosion resistance.

- For Use With: Air, Natural Gas, Water, Hydraulic Fluid
- Specifications Met:
1/8-3/8, 3/4 Pipe Sizes: ANSI/ASME B31.3, ANSI/ASME B1.20.1, ANSI/ASME B31.1, ASTM A108
1/2 Pipe Size: ANSI/ASME B31.3, ANSI/ASME B1.20.1, ANSI/ASME B31.1, ASTM A576
High-Pressure Socket-Connect
Steel Unthreaded Pipe Fittings
Socket-connect fittings are easier to weld than butt-weld fittings because the fitting doesn’t need to align perfectly to the pipe. Slide pipe into the socket and weld for a strong, permanent connection. Fittings have heavy duty construction that stands up to high-pressure applications. They are for use in noncorrosive environments.
