2 Pack XFITTING 1/2 Pex B x 3/4 GHT Hose Bibb with Flange, Brass Garden Valve

Types of PEX Fittings:

Crimp Fittings are the most common type of PEX fittings and 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, do not require any special tools. They have a ring inside that grips the PEX pipe securely when pushed together.

Compression 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 utilize 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.

Specific fitting types include Pex Tee, Pex Plug, Pex Stub Out, Pex Female Elbow, and Drop Ear Pex Elbow.

Installation Steps:

1. Prepare the Pipe: Cut the PEX pipe to the required length using a PEX pipe cutter ensuring a clean and square cut.

2. Deburr the Pipe: Remove any rough edges or burrs from the cut end of the pipe using a deburring tool to ensure a smooth connection and prevent damage to the fitting.

3. 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.

4. Crimp the Ring: Center the crimp ring over the fitting and pipe joint and use a crimp tool to compress the ring firmly around the pipe following the manufacturer's specifications.

5. Check the Connection: After crimping, visually inspect the connection to ensure the crimp ring is fully compressed without gaps between the pipe and fitting.

6. Pressure Test: Pressure test the system after all fittings are installed to check for leaks by pressurizing the system and monitoring for drops in pressure over time.

Tips for Working with PEX Fittings:

• Use PEX-specific fittings designed for PEX piping systems to ensure compatibility and reliability.
• Follow manufacturer guidelines and local plumbing codes when selecting and installing PEX fittings.
• Properly support and secure PEX piping to prevent stress on fittings and potential leaks.
• Consider using expansion fittings for installations in tight spaces or challenging crimp tool maneuvering.
• Keep a spare supply of fittings on hand for unexpected repairs or modifications.
