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.

High-Pressure Socket-Connect
Steel Unthreaded Pipe Fittings
Socket-connect fittings are easier to weld than butt-weld fittings because the fitting doesn’t need to align perfectly to the pipe. Slide pipe into the socket and weld for a strong, permanent connection. Fittings have heavy duty construction that stands up to high-pressure applications. They are for use in noncorrosive environments.
Tee outlets allow you to create a tap anywhere along a pipe. They are also known as branch connectors and are comparable to Sockolet. To install, drill a hole in your pipe to match the fitting’s pipe size and weld in place.

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. 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.

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.
