Plumbing- PEX systems Connector Guide

Connects for PEX systems are not interchangeable and all require specific crimping or connecting tools.

PEX systems offer a variety of connectors to suit different installation needs. Here are some common types of PEX connectors:

1. Crimp Fittings: These are the most common and affordable type of PEX fittings. They require a PEX crimp tool and copper crimp rings to secure the connection. Crimp fittings are compatible with all types of PEX tubing (A, B, and C).

2. Clamp (Cinch) Fittings: Similar to crimp fittings, but use stainless steel clamps instead of copper rings. They require a PEX clamp tool and are also compatible with all types of PEX tubing.

3. Push-Fit (Push-to-Connect) Fittings: These fittings do not require any special tools. They use a composite mechanism to lock and seal the pipe, making them easy to install and remove. Push-fit fittings are compatible with PEX, CPVC, and copper piping.

4. Expansion Fittings: These fittings require an expander tool and PEX sleeves to create a secure connection. They are typically used with PEX-A tubing and are not compatible with other types of PEX.

5. Compression Fittings: These fittings do not require special tools and are used with PEX-AL-PEX tubing. They use a compression nut and ring to create a secure connection.

6. Press Fittings: These fittings require a press tool and steel sleeves to create a secure connection. They are compatible with all types of PEX tubing.

PEX crimp connections

PEX crimp connections are a popular method for joining PEX tubing in plumbing systems. Here's a step-by-step guide to making a PEX crimp connection:

1. Cut the PEX tubing: Use a PEX cutter to ensure a smooth and even cut. Position the cutter at 90 degrees to the tubing.

2. Slide the PEX crimp ring: Slide the crimp ring over the tubing, approximately 2 inches past the end.

3. Insert the PEX fitting: Fully insert the PEX fitting into the tubing so that the fitting's shoulder touches the tubing.

4. Position the crimp ring: Position the crimp ring 1/4 to 1/8 inch from the end of the tubing, right above the fitting's barbs.

5. Crimp the ring: Open the jaws of the PEX crimp tool and position it over the crimp ring at 90 degrees to the tubing. Close the tool's jaws completely to crimp the ring.

6. Check the connection: Use a go-no-go gauge to ensure the connection is secure. If the connection doesn't gauge properly, use a decrimping tool to remove the crimp ring and redo the connection.

This method is suitable for all types of PEX tubing (A, B, and C) and is popular among DIY enthusiasts because of the ability to check the completed connection with a go-no-go gauge.

PEX Clamp Connections

PEX clamp connections are another popular method for joining PEX tubing, and they're known for their reliability and ease of use. Here's how to make a PEX clamp connection:

1. Cut the PEX tubing: Use a PEX cutter to ensure a clean and even cut. Make sure the cut is perpendicular to the tubing.

2. Slide the PEX clamp ring: Slide a stainless steel PEX clamp ring over the tubing, positioning it roughly 2 inches from the end.

3. Insert the PEX fitting: Fully insert the PEX fitting into the tubing, ensuring that the tubing is flush against the fitting’s shoulder.

4. Position the clamp ring: Slide the clamp ring over the tubing so that it’s centered over the fitting’s barbs.

5. Clamp the ring: Use a PEX clamp tool to compress the clamp ring. Place the tool’s jaws over the small tab on the clamp ring and squeeze the handles until the ring is fully compressed.

6. Check the connection: Verify that the ring is securely clamped and that the connection is tight by visually inspecting and gently pulling on the fitting.

PEX clamp connections are versatile and work with all types of PEX tubing (A, B, and C). The stainless steel clamp rings are resistant to corrosion and provide a strong, durable connection.

PEX Expansion Connecitons

PEX expansion connections are a reliable and secure method for joining PEX-A tubing. Here's a guide on how to make a PEX expansion connection:

1. Cut the PEX tubing: Use a PEX cutter to ensure a clean and straight cut. Make sure the cut is perpendicular to the tubing.

2. Expand the PEX tubing: Slide a PEX expansion ring onto the end of the tubing. Position the ring so it's flush with the end of the tubing.

3. Expand the tubing and ring: Use a PEX expansion tool to expand both the tubing and the ring. Insert the expansion tool's head into the tubing and squeeze the handles to expand the tubing. Rotate the tool slightly between expansions to ensure even expansion.

4. Insert the PEX fitting: Once the tubing and ring are expanded, quickly insert the PEX fitting into the tubing. The tubing will contract around the fitting, creating a secure connection.

5. Check the connection: Ensure the connection is secure by visually inspecting and gently tugging on the fitting.

PEX expansion connections are specifically designed for PEX-A tubing, as this type of PEX has the highest degree of flexibility and memory, allowing it to return to its original shape after expansion.
