High-Pressure Stainless Steel Threaded Pipe Fittings
Use these heavy duty fittings in high-pressure flow applications.
304 stainless steel fittings have very good corrosion resistance. 316 stainless steel fittings have excellent corrosion resistance. Tee outlets allow you to create a threaded outlet anywhere along a pipe. They are also known as branch connectors and are comparable to Thredolet. To install, drill a hole in your pipe to match the fitting’s pipe size and weld in place.

Thick-Wall Butt-Weld Stainless Steel Unthreaded Pipe Fittings
With a thicker wall than our standard-wall butt-weld pipe fittings, these offer high strength while providing a smooth connection for maximum flow. They have beveled ends that, when flush to pipe, create a trough for a leak-resistant, permanent weld.
304 stainless steel fittings have very good corrosion resistance. 316 stainless steel fittings have excellent corrosion resistance.
Tee outlets allow you to create a tap anywhere along a pipe. They are also known as branch connectors and are comparable to Weldolet. To install, drill a hole in your pipe to match the fitting’s pipe size and weld in place.

High-Pressure Iron and Steel Threaded Pipe Fittings
These fittings can stand up to high-pressure applications. Use them in noncorrosive environments.
Tee outlets allow you to create a threaded outlet anywhere along a pipe. They are also known as branch connectors and are comparable to Thredolet. To install, drill a hole in your pipe to match the fitting’s pipe size and weld in place.
Phosphate-coated and zinc-phosphate-coated fittings offer some corrosion resistance, but aren't intended for corrosive 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 Butt-Weld Steel Unthreaded Pipe Fittings
Butt-weld fittings allow for a smooth connection that provides maximum flow. They have beveled ends that, when flush to pipe, create a trough for a strong, permanent weld. Fittings are also known as Schedule 40. They are for use in noncorrosive environments.
Tee outlets allow you to create a tap anywhere along a pipe. They are known as branch connectors and are comparable to Weldolet. To install, drill a hole in your pipe to match the fitting's pipe size and weld in place.

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.
Tee outlets allow you to create a tap anywhere along a pipe. They are also known as branch connectors and are comparable to Sockolet. To install, drill a hole in your pipe to match the fitting’s pipe size and weld in place.
