Copper/brass pipe extension VIEGA 15 mm x 1/2" (model 100049)

VIEGA copper/brass pipe extension 15 mm x 1/2" is a compact fitting intended to connect 15 mm copper or brass tubing to 1/2" threaded components. Manufactured from brass, the extension provides corrosion resistance and the mechanical strength required for use in water supply and heating systems. The product creates a reliable transition between metric tubing and imperial threaded fittings while maintaining a small installation footprint.

Advantages

The brass construction ensures long-term resistance to corrosion and mechanical wear in typical potable water and heating applications. Its design provides a secure threaded connection to 1/2" components while fitting snugly onto 15 mm tubing, reducing the need for additional adapters. The compact form factor simplifies installation in confined spaces and supports standard plumbing practices without altering system hydraulics significantly.

Suitable for

• Connecting 15 mm copper or brass tubing to 1/2" threaded valves and fittings
• Domestic water supply installations
• Heating system connections and radiator valves
• Retrofit work where metric-to-imperial transitions are required

Key specifications

• Material: brass (copper-alloy)
• Connection 1: designed for 15 mm copper/brass tubing
• Connection 2: 1/2" external/internal threaded interface compatible with standard plumbing threads
• Application: potable water and heating systems
• Design: compact inline extension for metric-to-imperial transitions

How to use

Ensure the piping and threaded component threads are clean and free of debris before installation. Insert or secure the 15 mm tubing end according to the tubing joining method used in your system (e.g., compression, soldering or press connection) and tighten the 1/2" threaded connection with appropriate tools to the torque recommended for the mating fitting. Confirm leak-tightness by pressurizing the system and inspecting joints; follow applicable local plumbing codes and standards during installation.

Usage recommendations

Use the extension only in compatible potable water and heating systems. Avoid exposing the fitting to aggressive chemicals or environments outside the specified service conditions. When combining with different metals, consider corrosion control measures such as dielectric unions or appropriate sealing compounds to prevent galvanic corrosion. Periodically inspect connections for signs of leakage or deterioration as part of routine maintenance.
