Alkotest KZ2512 Kolanko GZ FI25x1/2 – pipe elbow fitting, threaded GZ, 25 mm x 1/2"

Alkotest KZ2512 Kolanko GZ FI25x1/2 is a 90° elbow pipe fitting with a male threaded (GZ) connection designed to join a 25 mm pipe to a 1/2" threaded outlet. The fitting provides a compact transition and change of flow direction in plumbing systems. It is suitable for use in general water supply and utility pipelines where a durable, threaded elbow is required for reliable mechanical connection and simple assembly.

Advantages

This elbow fitting offers a compact 90° turn with a threaded male connection that facilitates secure, removable joints without soldering or adhesive. Its dimensional conversion between 25 mm and 1/2" simplifies integration between metric pipework and BSP/pipe-threaded components. The threaded design supports straightforward installation and maintenance while providing a stable mechanical seal when used with appropriate thread sealant or tape.

Suitable for

• Domestic and commercial water supply installations
• Connections between 25 mm pipes and 1/2" threaded fixtures or valves
• Repair or modification of existing plumbing systems requiring a threaded elbow
• Utility pipelines where a compact 90° transition is needed

Key specifications

• Function: 90° elbow for changing pipe direction
• Connection type: male threaded (GZ)
• Pipe size transition: 25 mm to 1/2"
• Compatibility: suitable for standard plumbing threads and 25 mm pipe systems
• Use: designed for water and general utility pipelines

How to use

Prepare the mating threads and the 25 mm pipe according to the plumbing system in use. Apply appropriate thread sealant or PTFE tape to the male threads to ensure leak-tight jointing. Screw the fitting into the corresponding 1/2" threaded component until hand-tight, then use suitable tools to complete tightening without over-stressing the fitting. Connect the 25 mm pipe securely using the method appropriate for that pipe type (e.g., compression, push-fit, or threaded socket). After assembly, pressure-test the system following local codes and manufacturer guidance to confirm there are no leaks.

Usage recommendations

Use compatible sealants and avoid excessive torque during installation. Verify material compatibility with the fluid and operating temperatures in your system. For long-term reliability, inspect threaded joints periodically and retighten or reseal as needed according to maintenance schedules.
