Adapter clamp Varioterm GW 3/4" x 15 x 1 for piping, white (ZZM1506)

Varioterm adapter clamp GW 3/4" x 15 x 1 (model ZZM1506) is a white pipe connection fitting designed to join 15 mm piping to a 3/4" threaded valve or fixture. It provides a compact mechanical transition between plastic or metal tubing and a 3/4" external thread, intended for use in heating, plumbing and sanitary installations where a reliable sealed coupling is required. The adapter clamp is produced to fit standard 15 mm pipe dimensions and standard 3/4" threaded connections, offering a space-saving option for branch-offs, appliance connections and repair work.

Advantages

The adapter clamp offers a straightforward, low-profile connection that minimizes pipe protrusion and supports stable mechanical fastening. Its white finish helps it blend into visible installations and sanitary environments. Designed for compatibility with both plastic and metal 15 mm pipes, the fitting reduces the need for additional adapters and simplifies assembly while maintaining a consistent sealing interface to 3/4" threaded valves and fixtures.

Suitable for

• Connecting 15 mm plastic or metal pipes to 3/4" threaded valves and fixtures
• Heating system branch-offs and radiator connections
• Plumbing repairs and retrofits where compact transitions are required
• Sanitary installations such as mixers, faucets and small appliances

Key specifications

• Connection type: mechanical adapter clamp for 15 mm pipe to 3/4" external thread
• Pipe size compatibility: 15 mm (OD/standard for 15 mm systems)
• Thread type: 3/4" external threaded connection suitable for common valves and fixtures
• Color / finish: white
• Material compatibility: suitable for use with plastic (e.g., PEX, PB) and metal (e.g., copper, multi-layer) 15 mm pipes
• Typical application areas: heating, plumbing and sanitary installations

How to use

Prepare the 15 mm pipe by cutting it squarely and removing any burrs or debris. Slide the adapter clamp onto the pipe until it seats fully, then tighten the clamp mechanism according to the manufacturer's guidance to secure the mechanical seal. Screw the 3/4" threaded end onto the matching valve or fixture, ensuring appropriate thread sealant or tape is used where required to achieve a leak-free joint. After assembly, check the connection under working pressure for any leaks and retighten if necessary following safe installation practices.

Usage recommendations

Use the adapter clamp in systems with compatible pipe and thread standards; confirm pressure and temperature limits of the overall system before installation. When connecting to water-carrying fixtures, employ suitable thread sealant and perform a pressure test after assembly. Where visual appearance matters, the white finish is suited to exposed sanitary fittings; avoid aggressive solvents that could affect seal components.
