How to Use SharkBite Fittings on PEX Pipe: A Comprehensive Guide

Whether you’re a seasoned plumber or a DIY enthusiast, understanding how to use SharkBite fittings on PEX pipe will offer you a quick, easy, and reliable method for connecting pipes without soldering, clamps, or glue.

These push-to-connect fittings are particularly beneficial for working with PEX (cross-linked polyethylene) pipes, and this comprehensive guide will delve into the essential steps and tips for successful installation.

The Basics:

  1. Precise Cuts: Ensure you have a clean, perpendicular cut on the PEX pipe using a PEX cutter or a sharp utility knife. This creates a perfect foundation for a tight seal.
  2. Deburring: Remove any burrs or rough edges from the cut end of the pipe using the deburring tool. This prevents damage to the O-ring within the SharkBite fitting.
  3. Depth Gauge: Mark the insertion depth on the pipe using the SharkBite depth gauge tool. This helps ensure the pipe is fully inserted into the fitting for a secure connection.
  4. Push & Connect: Insert the PEX pipe into the SharkBite fitting until it reaches the depth mark. You’ll feel the pipe “bottom out” when fully seated.

Additional Tips:

  1. Compatibility: Choose SharkBite fittings with tan collars designed explicitly for PEX, copper, CPVC, PE-RT, and HDPE pipes. Always cross-check the fitting’s specifications to ensure it matches your application.
  2. Underground Protection: For underground installations, wrap SharkBite fittings with silicone tape for a watertight and airtight seal. This protects the brass fittings from ground contaminants and maintains the 25-year warranty’s validity.
  3. Double-Check Connections: After installing a SharkBite fitting, gently tug the pipe to confirm its secure connection. An adequately installed fitting should resist easy removal.
  4. Support Liners: When connecting PEX to a SharkBite fitting, consider using a support liner inside the pipe. This prevents PEX from collapsing or deforming over time, potentially leading to leaks. Support liners are handy for high-temperature applications or situations where PEX might experience mechanical stress.

Conclusion:

SharkBite fittings offer a convenient and reliable solution for connecting PEX pipes in various plumbing applications. You can achieve leak-free, long-lasting connections by following these basic steps and incorporating the additional tips. Always consult local building codes and manufacturer instructions for specific requirements and best practices for any plumbing project.
