Oct. 14, 2023


If you're planning a plumbing project, you've likely heard about the benefits of using PEX (cross-linked polyethylene) pipes. They're known for their flexibility, durability, and cost-effectiveness. However, installing PEX pipes requires the use of fittings to create secure connections, and one of the most popular methods is PEX press fittings. In this guide, we'll walk you through the installation process of PEX press fittings, with a focus on the RIFENG system.


RIFENG is a recognized brand in the plumbing industry known for producing high-quality PEX press fittings. These fittings are designed to provide a leak-free and long-lasting connection between PEX pipes, making them a reliable choice for both DIY enthusiasts and professional plumbers.


Tools and Materials You'll Need:

Before you start, gather the following tools and materials:

  • PEX tubing
  • PEX press fittings (RIFENG or other trusted brands)  
  • PEX crimping tool
  • PEX cutter    
  • Deburring tool
  • Marker
  • Safety glasses
  • Gloves
  • Measuring tape


Step-by-Step Installation Guide:

Measure and Cut:
Measure the length of PEX tubing you need and use a PEX cutter to make a clean, square cut. Ensure the ends of the tubing are straight and free from burrs.

Deburr the Ends:
Use a deburring tool to remove any rough edges or burrs from the cut ends. This step is crucial to ensure a proper seal.

Mark the Depth:
Mark the insertion depth on the PEX tubing. The depth will depend on the specific PEX press fitting you're using, so refer to the manufacturer's instructions for guidance.

Insert the Fitting:
Slide the PEX press fitting onto the PEX tubing, ensuring it goes to the marked depth. Make sure the fitting is properly seated.

Press the Fitting:
Use a PEX crimping tool designed for PEX press fittings to secure the connection. The tool will compress the fitting onto the tubing, creating a strong, watertight seal.

Inspect and Test:
Inspect the connection to make sure there are no visible gaps or leaks. Once you're satisfied, you can conduct a pressure test to ensure the system is watertight.


Tips for a Successful Installation:

  • Follow the manufacturer's guidelines for specific RIFENG fittings.
  • Ensure the PEX tubing is clean and free from debris.
  • Use proper safety gear like safety glasses and gloves.
  • Double-check your measurements to avoid unnecessary cuts and fittings.
  • Test the system for leaks before covering the installation with drywall or insulation.
  • By following these steps and using high-quality PEX press fittings like those from RIFENG, you can ensure a reliable and leak-free plumbing system in your home. Whether you're working on a DIY project or a professional installation, the RIFENG system can help you achieve the results you desire.
