2. Type of Connection

There are several ways to connect PEX fittings to PEX pipes, each with its advantages and disadvantages:

  • Crimp: Crimp fittings utilize a specialized tool to compress a ring around the fitting, securing the PEX pipe. They offer a reliable and secure connection that is relatively easy to install.
  • Push-to-Connect: Push-to-connect fittings are designed for quick and simple installation. They simply push onto the PEX pipe, creating a secure connection without the need for tools. While convenient, they are not always recommended for high-pressure applications or in areas where vibration or movement is expected.
  • Expansion: Expansion fittings utilize a specialized tool to expand the fitting, creating a tight seal around the PEX pipe. This type of connection is commonly used for larger diameter pipes and is known for its strength and durability.

3. Temperature Rating

Different PEX fittings are rated for specific temperature ranges, ensuring their ability to withstand the temperature of the water flowing through them. Before choosing a fitting, consider the intended application:

  • Cold Water: For cold water applications, standard PEX fittings with a temperature rating of up to 140°F are generally sufficient.
  • Hot Water: For hot water applications, ensure the fittings are rated for a temperature range of at least 180°F or higher.

4. Pressure Rating

PEX fittings are rated for specific pressure levels, ensuring they can withstand the force of the water flowing through them. Choose a fitting with a pressure rating that exceeds the expected pressure in your plumbing system:

  • Residential Applications: Most residential plumbing systems operate at pressures between 40 and 80 PSI.
  • Commercial Applications: Commercial plumbing systems often experience higher pressures, requiring fittings with a higher pressure rating.

5. Durability and Resistance

PEX fittings need to be durable enough to withstand the wear and tear of a plumbing system, as well as resist corrosion and chemical damage:

  • Corrosion Resistance: Choosing fittings made from materials like brass, stainless steel, or CPVC offers excellent corrosion resistance. These materials are less likely to rust or degrade over time, ensuring a long lifespan for your plumbing system.
  • Chemical Resistance: If your plumbing system will be exposed to chemicals, choose fittings specifically designed for chemical resistance. CPVC and stainless steel fittings are often recommended for these applications.

6. Compatibility

Ensure that the PEX fittings you choose are compatible with the PEX pipe you are using. Different types of PEX pipes require specific fittings, and using incompatible fittings can lead to leaks or other problems:

  • PEX Pipe Type: PEX pipes come in different types, including PEX-A, PEX-B, and PEX-C. Each type of PEX requires specific fittings designed for compatibility.
  • Fitting Type: Ensure that the fittings you choose are compatible with the specific type of PEX pipe you are using.

7. Manufacturer and Warranty

Choosing fittings from reputable manufacturers with a strong track record of quality and reliability can help ensure a durable and reliable plumbing system:

  • Brand Reputation: Research and select fittings from reputable brands known for their high-quality products and excellent customer service.
  • Warranty: Look for fittings that come with a warranty, providing peace of mind and ensuring that you are covered in case of defects or issues.

Finding the best fittings for PEX involves considering factors like material, connection type, temperature rating, pressure rating, durability, compatibility, and manufacturer reputation.
