High-Pressure Socket-Connect Stainless Steel Unthreaded Pipe Fittings
Forged for excellent strength, these heavy duty socket-connect fittings stand up to high-pressure applications. They 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.
304 stainless steel fittings have very good corrosion resistance. 316 stainless steel fittings have excellent corrosion resistance.
Union straight connectors separate into three pieces for access to your line.
Socket connect x butt weld straight adapters are also known as half couplings.
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 Stainless Steel Unthreaded Pipe Flanges
Use these heavy duty forged flanges for high-pressure applications. Bolt two flat-surface flanges or two raised-surface flanges of same size together with a gasket (sold separately) to create an access point in a pipe line.
304 stainless steel flanges offer very good corrosion resistance. 316 stainless steel flanges have excellent corrosion resistance.
Socket-connect flanges have an internal stop that supports the pipe when welding and prevents the pipe from sliding all the way through.

- For Use With: Air, Water, Hydraulic Fluid, Natural Gas, Steam, Oil
- Specifications Met: ASTM A312
- Fittings: Use Class 3000 or Schedule 80 stainless steel
- Flanges: Use Class 300 or 600 stainless steel
Also known as Schedule 80, this pipe provides an extra-strong connection. Weld it to fittings and additional lengths of pipe. Welded connections are stronger than threaded connections and less likely to leak. Pipe is seamless with a smooth interior for unrestricted flow.
304 stainless steel pipe has very good corrosion resistance. 316 stainless steel pipe has excellent corrosion resistance.
