How to Identify and Measure Fittings
Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

Thick-Wall Plastic Pipe Fittings for Water
Connect these fittings to Schedule 80 pipe–they have thicker, stronger walls than standard-wall fittings so they can handle heavy duty industrial plumbing and water supply applications, such as water processing, waste water treatment, and irrigation. Fittings are plastic for good corrosion resistance. They meet ASTM specifications and testing requirements for material quality.
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. For plastic threads, apply a non-hardening, plastic-compatible sealant. Tape or sealants with PTFE are not recommended for plastic-to-plastic connections. For metal threads, use PTFE tape. When making a threaded connection be careful not to overtighten the threads. To prevent cracks and leaks, finger tighten the fitting, then wrench-tighten one to two turns.
Fittings that meet ASME B1.20.1 adhere to specifications for thread dimensions.
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: ASME B1.20.1, ASTM D1784
Fittings with Stainless Steel Threads: ASTM D1784 - Pipe Nipples and Pipe: Use Schedule 80 Brass, Copper, PVC Plastic
Fittings with Stainless Steel Threads: Use Schedule 80 PVC Plastic, Stainless Steel - Flanges: Use Class 150 PVC Plastic
Fittings with stainless steel collar have a reinforcement on the female threads to prevent the threads from cracking.
Fittings with metal threads allow you to transition to a brass, copper, or stainless steel pipe or fitting.

Saddle-tap tee adapters allow you to create additional outlets and connections in metal or plastic pipe. To install, shut down your line and drill a hole in the pipe where you want to create a connection. Position the saddle over the hole so the gasket and lip are fully engaged and secure with the included nuts, bolts, and washers.

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. For plastic threads, apply a non-hardening, plastic-compatible sealant. Tape or sealants with PTFE are not recommended for plastic-to-plastic connections. For metal threads, use PTFE tape. When making a threaded connection be careful not to overtighten the threads. To prevent cracks and leaks, finger tighten the fitting, then wrench-tighten one to two turns.
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.
