 Pipe compatibility: outer diameter 18 mm (3/4" nominal application)
 Material characteristics: corrosion-resistant metal components suitable for heating and plumbing environments
 Connection method: mechanical clamping without soldering
 Typical application area: heating circuits and potable water installations where clamp fittings are specified
How to use
Prepare the pipe end by ensuring it is clean, free of burrs and cut square. Slide the clamp connector onto the pipe until it seats fully, aligning the connector with the mating fitting or valve. Tighten the clamp mechanism according to the manufacturer's recommended torque or until the connector secures firmly to the pipe. Inspect the joint visually and, where appropriate, perform a pressure test to confirm leak-free installation before returning the system to service.
Usage recommendations
Use the clamp connector only on pipes with the specified outer diameter (18 mm). Follow applicable local regulations and manufacturer instructions for installation torque and testing. For critical installations, verify compatibility with system media (potable water, heating fluids) and consider supplementary sealing checks when connecting to mixed-material plumbing components.
