Types of PEX Fittings:
- Crimp Fittings: These are the most common type of PEX fittings. They require a crimp tool to compress a metal ring (crimp ring) around the PEX pipe and fitting, creating a secure connection.
- Push-Fit Fittings: Also known as push-to-connect or quick-connect fittings, these fittings don't require any special tools. They have a ring inside that grips the PEX pipe securely when pushed together.
- Compression Fittings: These fittings use compression nuts and rings to create a watertight seal. They are commonly used for repairs or when transitioning between PEX and other types of pipes.
- Expansion Fittings: Expansion fittings use a specialized tool to expand the PEX pipe, allowing the fitting to slide inside. When the pipe returns to its original size, it creates a tight seal around the fitting.
Installation Steps:
- Prepare the Pipe: Cut the PEX pipe to the required length using a PEX pipe cutter. Ensure that the cut is clean and square.
- Deburr the Pipe: Use a deburring tool to remove any rough edges or burrs from the cut end of the pipe. This ensures a smooth connection and prevents damage to the fitting.
- Insert the Fitting: For crimp fittings, slide the crimp ring onto the pipe first, then insert the fitting into the end of the pipe until it reaches the shoulder of the fitting.
- Crimp the Ring: Position the crimp ring over the fitting and pipe joint, ensuring it is centered. Use a crimp tool to compress the ring firmly around the pipe. Check the manufacturer's specifications for the correct crimping tool and technique.
- Check the Connection: After crimping, visually inspect the connection to ensure that the crimp ring is fully compressed and there are no gaps between the pipe and fitting.
- Pressure Test: Once all fittings are installed, pressure test the system to ensure there are no leaks. This involves pressurizing the system with air or water and checking for any drops in pressure over a period of time.

I used this ball valve connecting an instant hot water tank and it worked without any incident.

I really only needed one valve but for the price I figured that I might as well get two. An extra 1/2 inch PEX B ball valve can be handy.I'm using the valve to control the flow of the water to the cooling tower on my engine dyno. I had to replace a thermostatic valve that had failed and is no longer available and I switched to using an electronically controlled valve to maintain the temperature of the engine. This worked ok but the problem was the 3/4 inch valve would slam open and flow way more water way more quickly than what was needed for cooling. What I needed was a small valve that I could use to adjust/reduce that flow and one of these is perfect.It only took a few minutes to install the valve using my PEX tools and copper ring clamps. No leaks, no fuss, perfect.
