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.

Weather-Resistant EPDM Rubber Rods
Made of EPDM, these rods are resistant to sunlight, ozone, and water. They’re sized to seal narrow spaces, such as channels.
Rods for use with drinking water meet NSF/ANSI 61 standards for use in drinking water systems. They’re also FDA compliant for direct contact with food. These rods are often used to make seals and gaskets for equipment that processes food or water.
- Color: Black
- Temperature Range: -65° to 300° F
- Tensile Strength: 1,450 psi
- For Use Outdoors: Yes
- Specifications Met: ASTM D2000 M CA 810 Z1, FDA Compliant 21 CFR 177.2600, NSF/ANSI 61, NSF/ANSI 372
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: See table
- Pipe Nipples and Pipe: See table
- 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 or bronze pipe or fitting.
Unions separate into three pieces so you can access your line without unthreading pipe connections.

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.

Thick-Wall Plastic Pipe Fittings for Water
Connect these fittings to Schedule 80 pipe. With thicker, stronger walls than standard-wall fittings, they can handle heavy duty supply applications, such as water processing, wastewater 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).
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.
