Standard-Wall Plastic Pipe Fittings for Water
Connect these fittings to Schedule 40 plastic pipe–they are the industry standard for residential and commercial low-pressure plumbing and water supply applications. They are plastic for good corrosion resistance.
Attach socket-connect ends to unthreaded pipe or another socket-connect fitting with a PVC primer and cement (also known as solvent weld).
Fittings that meet ASTM D1784, ASTM D1785, and ASTM D4066 adhere to specifications and testing requirements for material quality.
Note: For fittings that are not rated for pressure, you can use the pressure rating of the plastic pipe as a reference. Threaded fittings are limited to 50% of the rated pressure of the pipe.
Warning: Never use plastic pipe fittings and pipe with compressed air or gas.
- For Use With: Water
- Maximum Temperature: 140° F
- Specifications Met: ASTM D1784
- Pipe Nipples and Pipe: Use Schedule 40 PVC Plastic
- Flanges: Use Class 150 PVC Plastic
Cut-to-angle elbow connectors come in two pieces and can be cut to any angle you need. They have molded cutting guides at 22 1/2°, 33 3/4°, 45°, 56 1/4°, 67 1/2°, 78 3/4°, and 90° angles. They also come with a template for custom angles. After cutting, bond the removable socket end to the cut piece with PVC primer and cement.
