## Long description

Connection fitting REHAU G 3/4–15 is a plumbing coupling intended for systems that require a G3/4 threaded connection and a nominal size 15. The fitting serves as a compact adapter to join pipes or hoses to fixtures with a G3/4 thread, enabling secure water distribution and heating system connections. Its design focuses on reliable mechanical connection and compatibility with standard G3/4 threaded components.
Advantages
The coupling offers a straightforward threaded connection that ensures a consistent seal when installed correctly. Its compact dimensions and nominal size 15 make it suitable for installations where space is limited.

Suitable for
Connecting pipes or hoses to fixtures with G3/4 threaded ports

Key specifications
Thread type: G3/4 (BSPP parallel thread)
Nominal size: 15
Application: plumbing and heating connections for water systems
Connection form: threaded coupling for G3/4 ports
How to use
Prepare mating threads by cleaning and, if recommended for the application, apply appropriate sealant or tape compatible with potable water and heating systems. Align the fitting with the G3/4 threaded port and hand-start the thread to avoid cross-threading, then tighten to the required torque with suitable tools. Verify the integrity of the connection by conducting a pressure test according to system requirements and check for leaks before placing the system into regular operation.
Usage recommendations
Use compatible materials and thread sealants approved for potable water or heating installations, and follow local plumbing codes. For best results, inspect threads for damage before installation and avoid excessive torque to prevent deformation. If in doubt, consult installation guidelines for the overall plumbing or heating system.
