Socket-Connect Fittings for Stainless Steel Tubing
- For Use With: Air, Hydraulic Fluid, Water
- Tubing: Use with seamless or welded 304 or 316 stainless steel that meets ASTM A269
Easier to weld than butt-weld fittings, these fittings don’t need to align perfectly to tubing. Insert tubing into the socket end and weld to create a permanent, leak-tight connection. Fittings are 316 stainless steel for excellent corrosion resistance.

Aboveground Standard-Wall PVC Pipe Fittings for Drain, Waste, and Vent
- For Use With: Water
- Max. Temperature: 140° F
- Specifications Met: ASTM D1784, ASTM D2665
- Pipe Nipples and Pipe: Use Schedule 40 PVC Plastic
- Flanges: Use Schedule 40 PVC Plastic
These Schedule 40 fittings are the industry standard for gravity-flow drain, waste, and vent (DWV) applications. Fittings are PVC, which has good corrosion resistance. They meet ASTM D1784 and ASTM D2665 specifications and testing requirements for material quality.
Attach socket-connect ends to unthreaded pipe or another socket-connect fitting with a PVC primer and cement (also known as solvent weld).
Warning: Never use plastic pipe fittings and pipe with compressed air or gas.
For technical drawings and 3-D models, click on a part number.
Fittings with a compression end are also known as slip-joint fittings. Insert the tube into the compression end and turn the nut until hand tight. Since you don't have to wait for cement to dry, they are quicker to install than socket-connect fittings.
