PEX Choosing the Right Crimping Connector for Your Project

PEX (cross-linked polyethylene) piping systems have become increasingly popular in the plumbing industry due to their flexibility, durability, and ease of installation. One critical component of Cross-linked Polyethylene piping systems is the connector used to join Cross-linked Polyethylene pipes. In this article, we will explore how to choose the right Cross-linked Polyethylene crimping connector for your project. We will discuss the different types of PEX crimping connectors, the factors to consider when selecting a connector, and tips for proper installation.

Types of Cross-linked Polyethylene Crimping Connectors:

Brass PEX Press Fittings

Copper Rings: Copper rings are the most commonly used crimping connectors. They are affordable, easy to find, and compatible with most PEX piping systems.

Stainless Steel Rings: Stainless steel rings are more expensive than copper rings but offer greater resistance to corrosion and chemical damage.

Sleeves: Sleeves are a newer type of crimping connector that use a compression sleeve instead of a ring. They offer a sleeker appearance and a more secure connection than traditional crimping connectors.

Factors to Consider When Selecting a Cross-linked Polyethylene Crimping Connector:

PEX Pipe Size: The crimping connector must match the size of the PEX pipe being used.

Material Compatibility: Ensure the connector matches the type of Cross-linked Polyethylene pipe, such as Cross-linked Polyethylene-A, -B, or -C.

Project Requirements: The connector must meet the specific needs of the project, such as pressure rating, temperature range, and application.

Tips for Proper Installation of PEX Crimping Connectors:

Use a Quality Crimping Tool: A high-quality crimping tool is essential for creating a secure and leak-free connection.

Inspect the Connector: Before installation, inspect the connector for any visible defects or damage.

Position the Ring Properly: Place the crimping ring over the crimping rib of the fitting and center the crimping tool over the ring.

Confirm a Tight Fit: After crimping, confirm that the connection is tight by attempting to pull the pipe out of the fitting.

Advantages of Cross-linked Polyethylene Crimping Connectors:

Cost-Effective: PEX crimping connectors are affordable and require fewer fittings and connectors, reducing material costs.

Quick and Easy Installation: The crimping process is quick and straightforward, saving labor time.

Durable and Reliable: PEX crimping connectors create a secure and leak-free joint that is resistant to corrosion, scale buildup, and chemical damage.


Choosing the right PEX crimping connector is crucial to the success of any Cross-linked Polyethylene piping project. Consider factors like pipe size, material compatibility, and project requirements to select the appropriate connector. Properly install with a quality crimping tool and inspect before use to ensure a secure, leak-free connection. Cross-linked Polyethylene crimping connectors offer cost-effectiveness, easy installation, and long-term durability, making them an excellent choice for plumbing professionals, pipe fitting manufacturers, and distributors.
