90° PEX/PEX Crimping Elbow (20)

Product detailed description

This 90° elbow is commonly used in residential and commercial building installations for redirecting PEX piping in heating, plumbing and sanitary applications. It is suitable for systems operating under standard hydraulic conditions and is frequently installed in underfloor heating, domestic hot and cold water supply, and central heating circuits. The fitting ensures a secure and leak-free connection when properly crimped, making it a reliable choice for installers working with PEX piping systems.

As a directional fitting, it is used to change the flow direction of the system by 90°. It is particularly useful in tight spaces where a right-angle turn is required without the need for additional fittings. The nickel-plated brass construction provides resistance to corrosion and ensures compatibility with PEX piping materials. The U-profile jaw crimping method ensures a strong mechanical bond between the pipe and the fitting.

Technical parameters

Code	PEX-Z.K20

The elbow is designed for PEX piping systems with a nominal diameter of 20 mm. The nickel-plated brass body ensures compatibility with PEX-A, PEX-B and PEX-C materials. The U-profile jaw crimping method requires a dedicated crimping tool to apply the correct pressure for a secure connection. The 10-year warranty reflects the expected service life under normal operating conditions.

Installation and connection

To install the 90° PEX/PEX crimping elbow, first ensure the PEX pipe is cut cleanly and free from burrs. Insert the pipe into the fitting until it reaches the stop mark. Position the U-profile crimp ring over the pipe and fitting junction. Use a compatible crimping tool to compress the ring around the pipe and fitting, ensuring a secure and leak-free connection. After crimping, inspect the joint for even compression and absence of gaps or misalignment. Common installation mistakes include using the wrong crimping tool, insufficient crimping pressure, or failing to align the ring correctly before compression.

Compatibility and accessories

This elbow is compatible with PEX piping systems and requires a U-profile crimp ring and a suitable crimping tool for installation. Accessories such as crimping tools and rings should be selected according to the manufacturer's specifications. When planning an installation, ensure all fittings and tools are from the same system to maintain compatibility and system integrity.

Technical background for designers

The elbow operates by redirecting the flow of the system at a 90° angle. The nickel-plated brass body offers good mechanical strength and resistance to corrosion, making it suitable for use in both hot and cold water systems. The U-profile jaw crimping method ensures a secure mechanical bond between the PEX pipe and the fitting. The service life of the fitting is influenced by the quality of the crimping process, the compatibility of the PEX material, and the operating conditions of the system.

Service and operation

The fitting requires no regular maintenance under normal operating conditions. However, it is important to inspect the crimped joints periodically for signs of wear, leakage or corrosion. If any issues are detected, the affected joint should be replaced immediately. The 10-year warranty covers defects in materials and workmanship under normal use.

Frequently asked questions
