Compression Fitting Hydroland GZ 1/2" x 16 x 2 PEX White

The Hydroland Compression Fitting GZ 1/2" x 16 x 2 in white is a compact mechanical connector designed to join 16 mm PEX (cross-linked polyethylene) tubing to a 1/2" threaded inlet or outlet. Intended for potable water and heating systems, this compression-style fitting provides a sealed transition between flexible PEX pipe and standard threaded plumbing fixtures. Its reduced profile helps fit connections in confined spaces while maintaining a reliable seal for domestic plumbing repairs, extensions and installations.

Advantages

The compression design allows tool-assisted assembly without soldering or glue, offering a clean and fast connection method. Constructed with materials suitable for contact with drinking water, the fitting provides corrosion resistance and consistent mechanical performance under typical domestic water and heating temperatures. The white finish blends with light-coloured pipes and fittings and the compact body reduces space requirements at junction points.

Suitable for

• Connecting 16 mm PEX tubing to 1/2" threaded valves, radiators or fixtures
• Domestic potable water supply lines and heating circuits
• Plumbing repairs, retrofits and short extensions in tight spaces

Key specifications

• Connection types: compression for 16 mm PEX to 1/2" external threaded connection
• Pipe compatibility: 16 mm PEX (cross-linked polyethylene)
• Finish: white
• Application: potable water and heating systems
• Design: compact profile for limited-access installations

How to use

Ensure the PEX tubing is cut squarely and free from burrs, then slide the compression nut and ferrule onto the pipe. Insert the pipe fully into the fitting until it seats against the internal stop. Hand-tighten the compression nut and then secure it with an appropriate wrench to the recommended torque for compression fittings, ensuring a firm mechanical seal without over-tightening. Thread the 1/2" male or female counterpart into the threaded end and apply thread sealant or PTFE tape where required by the mating part. Verify the joint for leaks under normal system pressure before leaving the installation in service.

Usage recommendations

Use the fitting only with approved 16 mm PEX tubing and follow local plumbing codes. Avoid excessive bending or strain on the PEX tube near the joint and inspect connections after initial pressure testing. For long-term reliability, periodically check fittings in heating circuits subject to thermal cycling.
