## Long description

REHAU Reh-Zł.Prosta 16-16 His 259455 is a straight pipe fitting adapter designed to join two 16 mm pipes in plumbing and heating installations. The compact mechanical connector allows a direct, linear connection between equal-diameter plastic or multilayer pipes used in domestic water distribution, radiator circuits and underfloor heating manifolds where a 16 mm line is required.
Advantages
The adapter provides a simple and space-saving solution for creating reliable straight connections in 16 mm piping systems. Its mechanical design enables fast installation without the need for soldering or complex tools, while ensuring a secure seal suitable for potable water and heating applications. The small form factor supports installations in confined spaces and facilitates neat routing of supply lines.
Suitable for
 Connecting two 16 mm plastic or multilayer pipes in domestic water supply
 Radiator and convector connections requiring 16 mm lines
 Underfloor heating circuits and manifold branches with 16 mm piping
 Light commercial installations where compact straight joints are needed
Key specifications
 Connection type: straight mechanical pipe-to-pipe adapter for 16 mm pipes
 Pipe diameter: 16 mm (both ends)
 Compatibility: designed for commonly used 16 mm plastic and multilayer heating/water pipes
 Application: potable water distribution and heating systems
 Form factor: compact, low-profile inline connector
How to use
Prepare pipe ends by ensuring they are cut square and free of burrs or debris. Insert each 16 mm pipe end fully into the adapter until it seats securely according to the connector’s stop. Tighten or secure the mechanical elements as required by the adapter’s design to achieve a sealed joint. After installation, pressurize the circuit and inspect the connection for leaks. Follow applicable local plumbing and heating regulations during installation.
Usage recommendations
Use the adapter only with compatible 16 mm pipes and in systems where mechanical straight connections are suitable. Verify material compatibility and maximum operating pressure and temperature of the piping system. For installations in concealed locations or where code requires permanent joints, consider the appropriate joint type and consult technical documentation or a qualified installer.
