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.
Fittings for drinking water meet NSF/ANSI Standard 61.
Attach socket-connect ends to unthreaded pipe or another socket-connect fitting with a PVC primer and cement (also known as solvent weld).
To prevent leaks in threaded connections, apply a sealant to the male threads. Threaded connections can be taken apart as needed for maintenance and repair. For plastic threads, apply a non-hardening, plastic-compatible sealant. Tape or sealants with PTFE are not recommended for plastic-to-plastic connections. 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: Drinking Water, Water
- Maximum Temperature: 140° F
- Specifications Met: ASTM D1784, NSF/ANSI 61
- Pipe Nipples and Pipe: Use Schedule 40 PVC Plastic

Fittings with stainless steel collar have a reinforcement on the female threads to prevent the threads from cracking.

Sealed-End Round Cut-to-Length Shipping Tubes
Use scissors to cut these tubes down to the length you need. Tubes are oil and moisture resistant. They have one sealed end and one open end. Use them to protect long, thin objects during shipping. Add an end cap (sold separately) to close the open end.
