Can i use a brass compression valve on pex

When it comes to plumbing, one common question is: "Can I use a brass compression valve on PEX?" The answer isn't straightforward and depends on various factors. Let's dive into the details.

What Are Brass Compression Valves?

Brass compression valves are essential components in plumbing systems. They are used to control the flow of water through pipes. These valves consist of three main parts: the valve body, a compression nut, and a compression ring (also known as a ferrule). When tightened, the compression ring compresses against the pipe, creating a watertight seal.

Why Choose Brass?

• Durability: Brass is known for its strength and longevity.

• Corrosion Resistance: It resists corrosion better than many other metals.

• Lead-Free Options: Modern brass valves are often lead-free, making them safer for drinking water systems.

Steps to Use a Brass Compression Valve on PEX

Using a brass compression valve with PEX requires careful attention to detail. Here’s how you can do it:

Step 1: Gather Your Tools

• Brass compression valve

• PEX tubing

• Pipe cutter

• Deburring tool

• Adjustable wrench

Step 2: Cut the PEX Tubing

Use a pipe cutter to cut the PEX tubing to your desired length. Ensure that the cut is clean and straight.

Step 3: Deburr the Cut End

After cutting, use a deburring tool to smooth out any rough edges on the cut end of the PEX tubing.

Step 4: Insert the Compression Ring

Slide the compression nut onto the end of the PEX tubing followed by the compression ring.

Step 5: Attach the Valve Body

Insert the end of the PEX tubing into the valve body until it reaches its stop point.

Step 6: Tighten Everything Up

Tighten the compression nut onto the valve body using an adjustable wrench. Make sure it's snug but not overly tight to avoid damaging any components.

What to Pay Attention To

While installing a brass compression valve on PEX might seem straightforward, there are several key points you need to keep in mind:

Compatibility with F1960 Standard

Ensure that your brass compression valve is compatible with F1960 fittings if you're using this standard for your PEX connections. This ensures proper sealing and reduces leak risks.

Lead-Free Requirements

If you're working on potable water systems, make sure your brass valves are lead-free. This is crucial for health safety and compliance with regulations.

Proper Sizing (PEX * OD)

Ensure that you match your brass compression valve size with your PEX tubing's outer diameter (OD). Mismatched sizes can result in leaks or improper fittings.

Conclusion

So, can you use a brass compression valve on PEX? Yes, but with caution. Ensure compatibility with F1960 standards if applicable, opt for lead-free options for safety, and always match sizes correctly (PEX * OD). By following these steps and paying attention to these details, you can achieve a secure and efficient plumbing connection using brass compression valves on PEX tubing.
