Crimp elbow 90° reduced PEX/PEX (20x16)
Code: PEX-Z.KR20X16Product detailed description
The crimp elbow 90° reduced PEX/PEX is a fitting commonly used in residential and commercial heating and plumbing systems. It allows for a directional change while reducing pipe size from 20 mm to 16 mm. The fitting ensures secure, leak-free connections when installed correctly using dedicated crimp tools. It is suitable for potable water, central heating and underfloor heating systems.
Typical applications include installation behind walls, beneath floors or within ceiling cavities where space constraints require compact fittings. This elbow is preferred in systems where reliability and corrosion resistance are essential, especially in environments with fluctuating temperatures and pressures.

The fitting’s dimensions and material are specified according to the manufacturer’s standards. Tinned brass provides good resistance to corrosion and mechanical stress. The 20x16 mm size reduction requires careful alignment during installation to avoid flow restriction or misalignment.
Installation and connection
This elbow is installed using a crimping tool with U-profile jaws. Ensure the PEX tubing is cut cleanly and free from burrs. Slide the fitting onto the tube until it reaches the stop mark. Use the appropriate crimp ring and apply even pressure with the pliers to compress the ring around the tube and fitting. After crimping, verify the fit using a go/no-go gauge to confirm the correct deformation. Common errors include over-crimping, under-crimping, or using incorrect tooling, all of which can compromise the integrity of the joint.
Compatibility and accessories
This elbow is compatible with PEX tubing of the correct outer diameter for 20 mm and 16 mm nominal sizes. It is used in conjunction with PEX crimp rings, U-profile jaw pliers and inspection tools. Related items such as PEX crimp rings for 20 mm and 16 mm tubes should be selected based on the manufacturer’s specifications for the specific PEX grade in use.
Technical background for designers
The elbow operates by forming a rigid mechanical bond between the PEX tubing and the brass body through the crimping process. Tinned brass is selected for its durability and resistance to dezincification. The fitting is designed to maintain structural integrity under normal operating conditions of water and heating systems. Long-term performance depends on correct installation, proper tool calibration and the quality of the PEX material used.
Service and operation
Under normal operating conditions, the fitting does not require regular maintenance. However, during system inspections, check for signs of leakage, deformation or discolouration around the crimped joints. Any suspected failure should be investigated immediately. No scheduled service intervals are specified in the technical documentation provided by the manufacturer.
Frequently asked questions
Can this elbow be used with PERT or PEX-a tubing?
It is suitable for standard PEX tubing types. Consult the manufacturer’s technical data sheet for compatibility with specific PERT or PEX-a variants.
Is it possible to reuse this elbow after a failed crimp?
No. Once crimped, the fitting cannot be reused. A new fitting and crimp ring must be used for any replacement or repair.
What tools are required for installation?
A crimping tool with U-profile jaws is necessary to compress the crimp ring and form a secure connection.
Does the tinning affect the strength of the fitting?
Tinning enhances corrosion resistance without compromising mechanical strength. The brass core remains the primary load-bearing component.
