REHAU RAUTITAN LX transition elbow 40 - Rp 1 1/4 for piping connections

REHAU RAUTITAN LX transition elbow 40 - Rp 1 1/4 is a right-angle plumbing fitting designed to join RAUTITAN LX plastic piping to Rp 1 1/4 threaded metal fixtures. The component provides a secure transition between polymer pipe systems and conventional threaded connections, enabling reliable joints in heating, potable water and sanitary installations. It is suitable for new installations, repairs and retrofits where a threaded outlet is required.

Advantages

The transition elbow allows a compact 90° change of direction while preserving hydraulic performance and mechanical stability at the interface between plastic and metal parts. Its design reduces the need for additional adapters and minimizes potential leak points by providing a dedicated transition geometry. The fitting is compatible with standard RAUTITAN LX connection methods and supports installations in residential and commercial plumbing systems.

Suitable for

• Connecting RAUTITAN LX piping to Rp 1 1/4 threaded valves, radiators or fixtures
• Heating system manifolds and radiator connections
• Potable water distribution and sanitary fittings requiring a threaded interface
• Repair, retrofit and new-installation projects with mixed-material pipework

Key specifications

• Connection type: transition elbow, 90° angle between plastic pipe and threaded outlet
• Piping compatibility: RAUTITAN LX plastic pipe systems
• Thread size: Rp 1 1/4 female threaded interface
• Intended applications: heating, potable water and sanitary installations
• Typical installation environment: residential and commercial indoor plumbing

How to use

Prepare the RAUTITAN LX pipe according to the manufacturers cutting and insertion guidelines to ensure a clean, square end. Fit the pipe into the transition elbow using the prescribed RAUTITAN connection method, then tighten the Rp 1 1/4 threaded connection to the mating metal fixture using appropriate sealing tape or jointing compound if required by the system design. Verify alignment and torque recommendations from RAUTITAN LX installation instructions and perform a pressure test after installation to confirm leak-free operation.

Usage recommendations

Use compatible RAUTITAN LX installation tools and follow the system manufacturer's guidelines for pipe preparation, insertion depth and tightening torque. Avoid exposing the fitting to mechanical stress or corrosive environments incompatible with the materials used in both the plastic pipe and the threaded metal connection.
