REHAU pipe fitting T-connector with female thread 50 mm to Rp 1-50 (model 139812001)

REHAU pipe fitting T-connector with female thread 50 mm to Rp 1-50 (model 139812001) is a plastic plumbing and heating component designed to create a compact branch from a 50 mm pipe to a female Rp 1-50 threaded outlet. The fitting enables a transition from a smooth 50 mm pipe connection to a threaded branch suitable for valves, appliances, or downstream pipework that require Rp 1-50 thread engagement. It is intended for use in water distribution and heating system installations where a reliable, space-efficient threaded outlet is needed.

Advantages

The T-connector provides a stable, corrosion-resistant plastic construction that simplifies installation and reduces the need for additional adapters. Its integrated female Rp 1-50 thread offers a secure mechanical connection for threaded valves and fittings while maintaining a compact profile that minimizes space requirements in confined installations. The design supports standard joining methods for 50 mm piping and is compatible with typical plumbing system practices.

Suitable for

• Creating a threaded branch from 50 mm distribution pipes in plumbing systems
• Connecting valves, gauges or appliances with Rp 1-50 male threads
• Use in domestic water supply and heating manifolds requiring a compact outlet
• Retrofit and routine installation tasks where a threaded connection is preferred

Key specifications

• Material: durable plastic suitable for plumbing and heating applications
• Primary pipe connection diameter: 50 mm
• Threaded branch type: female Rp 1-50
• Configuration: T-connector with one threaded branch and two straight pipe connections
• Application: cold and hot water distribution, heating system branches

How to use

Prepare the 50 mm pipe ends according to the system's joining method (cut square, deburr and clean). Insert or join the pipe ends to the two straight connections of the T-connector using the appropriate installation technique for the pipe material and system (adhesive, mechanical coupling, or heat fusion where applicable). Ensure the female Rp 1-50 thread is clean and undamaged before attaching the mating male-threaded fitting. Apply appropriate thread sealant or tape where required by the installation practice to ensure a watertight connection. Tighten the mating fitting to the manufacturer's recommended torque to avoid over-stressing the plastic thread.

Usage recommendations

Verify compatibility of the T-connector with the specific pipe system and local plumbing codes. Use thread sealant or PTFE tape on the Rp 1-50 male threads as recommended for potable water or heating systems, and avoid excessive tightening to prevent thread deformation. Inspect the joint after initial pressure testing and during routine maintenance to ensure long-term leak-free operation.
