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.

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.
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: 180° F
- Pipe Nipples and Pipe: Use Schedule 40 PVC Plastic
Fittings with a compression end create a seal using a gasket and nut instead of cement or thread sealant, so they're quicker to install than socket-connect and threaded fittings. Insert the pipe and turn the end nuts until hand tight—the nuts compress the gasket against the pipe for a leak-resistant seal. This type of connection absorbs vibration and provides flexibility to reduce stress on your line.
Through-wall fittings are also known as bulkhead couplings and panel-mount couplings; they mount through a wall, tank, or panel to create an inlet or outlet for faucets, pipes, and spigots.

Through-wall fittings are also known as bulkhead couplings and panel-mount couplings; they mount through a wall, tank, or panel to create an inlet or outlet for faucets, pipes, and spigots. Fittings for curved tanks are curved to fit the contour of a rounded tank.
