Brass Compression Fittings for Pex Pipe Vs Brass Compression Fittings for Pex al Pex Pipe
What is brass compression fittings?
Brass compression fittings are widely used in plumbing and mechanical systems to connect pipes or tubes, providing a reliable and leak-proof joint without the need for soldering or welding. Here is a detailed breakdown of what brass compression fittings are:
1. Components
*Body: The main part of the fitting, typically made of brass, with threads on one or both ends to connect to pipe or tubing.
*Compression Nut: A brass nut that tightens over the pipe or tubing, compressing the ferrule and creating a seal.
*Ferrule (Olive): A small ring, usually made of brass or copper, that fits between the body and the compression nut. When the nut is tightened, it compresses the ferrule against the pipe or tubing, creating a tight seal.
2. Materials
Brass: Chosen for its excellent corrosion resistance, strength, and machinability, making it suitable for a wide range of applications.
How It Works
Cutting and Preparing the Pipe/Tubing: The pipe or tubing must be cut cleanly and squarely, with any burrs or rough edges removed.
Assembly: The compression nut is slid onto the pipe, followed by the ferrule.
Inserting the Pipe: The pipe or tubing is then inserted into the body of the compression fitting until it bottoms out.
Tightening: The compression nut is tightened onto the body, which compresses the ferrule against the pipe and the fitting, creating a watertight seal. Proper tightening is crucial; over-tightening can cause leaks or damage, while under-tightening may not secure the connection adequately.

Brass Compression Fittings for Pex Pipe
The brass compression fittings for Pex pipe are as the below picture show, they have 3 parts: the main body, the lock ring and the brass nut. The nuzzle of the body is without any O-rings. And the nuzzle size can beproduced as the Pipe sizes. For example, for the pipe size 16x2.0 or 16x2.2.

For the PEX-AL-PEX pipe, PE-AL-PE or PERT-AL-PERT, the brass compression fittings usually have 2 O-rings on the body as the picture show. And the other 2 parts, the brass ring and the nut are same as the Pex compression fittings. For the O-rings, the materials is NBR for cold water and gas system, and for hot water, usually use EPDM material.

What is Brass Press Fittings?
Brass press fittings have gained popularity in the plumbing and heating industries due to their efficient and reliable method for joining pipes. These fittings are designed to simplify installation and create secure, durable connections without the need for soldering, welding, or adhesives. Here's a comprehensive overview:
Components
Body: Made of brass, the body of the press fitting is designed to house the pipe and incorporate a sealing element.
Sealing Element: Typically, an EPDM (ethylene propylene diene monomer) O-ring is located inside the fitting to ensure a watertight seal.
Press Sleeve: Metal sleeves (often stainless steel) that surround the fitting’s body and are pressed onto the pipe using a specialized press tool, creating a permanent, secure joint.
How It Works
Cutting and Preparing the Pipe: The pipe must be cut cleanly and squarely, with any burrs or rough edges removed. Proper preparation ensures a leak-free connection.
Inserting the Pipe: The pipe is inserted into the brass press fitting until it reaches the proper depth, often marked on the fitting itself for accuracy.
Pressing: Using a press tool, the press sleeve is compressed onto the pipe and fitting. The tool squeezes the metal sleeve, deforming it to seal tightly around the pipe and the O-ring inside the fitting.
Brass Press Fittings for Pex Pipe vs Brass Press Fittings for Pex al Pex Pipe
As the below picture show, the main difference for the press fittings for pex pipe and pex al pex is the body and the O-rings. For the pex press fittings don’t have the O-ring. And the shape for the plastic block and Stainless steel sleeve has a little difference. But the installation method is the same for these 2 press fittings.
