Compatibility with PEX Tubing
When working with SharkBite fittings and PEX tubing, understanding compatibility is crucial for a successful and leak-free installation. SharkBite fittings are designed to work seamlessly with PEX tubing, but proper preparation of the tubing is essential. One common question is whether the plastic liner or ridge inside the PEX tubing needs to be removed before inserting it into the SharkBite fitting. The short answer is no—you do not need to remove the plastic ridge or liner. SharkBite fittings are engineered to accommodate the standard dimensions of PEX tubing, including any internal ridges or liners, ensuring a secure connection.
PEX tubing compatibility with SharkBite fittings is based on the tubing's outer diameter (OD) and the fitting's corresponding size. SharkBite fittings are available in sizes that match standard PEX tubing dimensions, such as 1/2-inch, 3/4-inch, and 1-inch. It is critical to ensure the PEX tubing is the correct size for the fitting to achieve a proper connection. Before insertion, the tubing should be cut cleanly and squared off using a PEX tubing cutter to avoid burrs or irregularities that could interfere with the fitting's sealing mechanism.
The design of SharkBite fittings includes stainless steel teeth and an O-ring that grip and seal the PEX tubing without requiring additional tools or adhesives. When the tubing is inserted, the fitting's components compress against the outer surface of the PEX, creating a watertight seal. The internal plastic ridge or liner of the PEX tubing does not hinder this process, as the fitting is designed to work with the tubing's standard specifications. Attempting to remove the ridge or liner is unnecessary and may damage the tubing, compromising the integrity of the connection.
It is important to note that SharkBite fittings are compatible with both cross-linked polyethylene (PEX-A, PEX-B, and PEX-C) tubing types, provided they meet the ASTM F876 and F877 standards. However, the tubing must be in good condition, free from cracks, kinks, or other damage. Properly preparing the PEX tubing by deburring the cut edge and ensuring it is free of debris will further enhance compatibility and performance with SharkBite fittings.
In summary, when using SharkBite fittings with PEX tubing, there is no need to remove the internal plastic ridge or liner.

Tools Needed for Proper Fitting
When working with SharkBite fittings, ensuring a proper and secure connection is crucial for leak-free plumbing. One common question that arises is whether you need to remove the plastic from the pipe before installing SharkBite fittings. The short answer is no—SharkBite fittings are designed to work with the plastic (or PEX) tubing without the need for removal. However, to achieve a proper fit, you’ll need the right tools to prepare the pipe and install the fittings correctly. Here’s a detailed guide on the tools needed for proper fitting.
Pipe Cutter or Tubing Cutter
A clean, straight cut is essential for a secure SharkBite connection. A pipe cutter or tubing cutter is the primary tool for this task. For PEX tubing, a dedicated PEX cutter is ideal as it ensures a square cut without burrs or deformities. If using copper pipes, a standard tubing cutter with a sharp wheel will suffice. Avoid using saws or knives, as they can leave uneven edges that compromise the fitting’s seal. Always measure and mark the pipe accurately before cutting to ensure the fitting aligns perfectly.
Deburring Tool
After cutting the pipe, small burrs or rough edges may remain. These can interfere with the SharkBite fitting’s O-ring and reduce the connection’s integrity. A deburring tool is essential to smooth out the pipe’s edge. For PEX tubing, a simple PEX deburring tool can be used to remove any excess material. For copper pipes, a reaming tool or a deburring brush will ensure the end is clean and ready for installation. This step is often overlooked but is critical for a leak-free connection.
Measuring Tape and Marker
Precision is key when working with SharkBite fittings. A measuring tape and a permanent marker are indispensable for marking the correct length of the pipe before cutting. Ensure the measurement accounts for the depth the pipe will insert into the fitting, typically indicated on the fitting itself. Accurate measurements prevent gaps or overextension, both of which can lead to leaks or fitting failure.
Adjustable Wrench or Pliers (Optional)
While SharkBite fittings are designed for hand-tight installation, having an adjustable wrench or pliers on hand can be useful for tightening stubborn connections or reaching fittings in tight spaces. However, avoid over-tightening, as this can damage the fitting or the pipe. Use these tools sparingly and only when necessary to ensure the fitting is secure without compromising its integrity.
SharkBite Depth Gauge (Optional but Recommended)
For those frequently working with SharkBite fittings, a depth gauge is a valuable tool. It ensures the pipe is inserted to the correct depth, which is critical for a proper seal. The gauge is placed over the fitting to verify the pipe’s insertion depth, eliminating guesswork and reducing the risk of leaks. While not mandatory, it adds an extra layer of precision to your work.
By equipping yourself with these tools—a pipe cutter, deburring tool, measuring tape, marker, and optionally a wrench or depth gauge—you’ll ensure that your SharkBite fittings are installed correctly and securely. Remember, the plastic on PEX tubing does not need to be removed, but proper preparation and the right tools are essential for a successful installation.
