Product Description

The compression fittings (brass pex fitting) are among the most popular choices for PEX pipe or PEX-AL-PEX pipe systems. These fittings are designed for reliability and ease of use, typically featuring two high-quality rubber O-rings positioned over the barbs to ensure a leak-proof seal.

Each fitting includes an insert that fits inside the tubing, a compression ring (split diagonally), and a compression nut. The unique advantage of this system is that it requires no specialized compression tools. A standard wrench or pliers is sufficient to tighten the nut over the compression ring. As the nut tightens, the diagonal cut in the ring closes, creating a secure, compressed connection.

Frequently Asked Questions

What types of pipes are these fittings compatible with?
These compression fittings are primarily designed for PEX and PEX-AL-PEX multilayer pipes used in water and gas systems.
Do I need any special tools for installation?
No, these fittings do not require expensive crimping or expansion tools. You only need a standard wrench or pliers to tighten the compression nut.
Are these fittings resistant to corrosion?
Yes, they are made from high-quality CW617N or HPb 58-3A brass, often featuring nickel plating for enhanced corrosion resistance.
What is the function of the double O-rings?
The double EPDM O-rings provide a dual-layer seal over the barbs, significantly reducing the risk of leaks in high-pressure environments.
Can these brass fittings be reused?
Because they are mechanically assembled rather than permanently crimped, they can be disassembled and reused, making them a sustainable choice.
What sizes are available for selection?
We offer a full range of sizes including 16mm, 18mm, 20mm, 25mm, 26mm, and 32mm to fit various plumbing requirements.
