These fittings can stand up to high-pressure applications. Use them in noncorrosive environments.

Socket-connect fittings are easier to weld than butt-weld fittings because the fitting doesn't need to align perfectly to the pipe. Slide the pipe into the socket and weld.

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.

Often used to find worn components or leaks, these flowmeters have a valve, so you can test the flow of oil from pumps and other equipment at different pressures.
