Manifold coupling ROTH 16 x 2 mm to 3/4" for plumbing distribution

ROTH manifold coupling 16 x 2 mm to 3/4" is a mechanical transition fitting designed for plumbing distribution systems. It connects 16 x 2 mm PERT/PEX pipes to 3/4" threaded manifolds, valves or adapters, providing a compact and reliable joint for heating and potable water circuits. The coupling is intended for installations where a durable, leak-resistant connection between small-diameter plastic pipework and standard 3/4" threaded components is required.

Advantages

The coupling offers a straightforward mechanical connection that simplifies installation and maintenance without the need for soldering or complex tools. It is manufactured to fit 16 x 2 mm pipe dimensions precisely, ensuring consistent sealing performance and reduced risk of leaks. Its compact design minimizes space requirements at manifold assemblies and makes it suitable for retrofit and new build applications. The fitting provides stable mechanical retention and is compatible with commonly used 3/4" threaded manifolds and valves.

Suitable for

• Connecting 16 x 2 mm PERT/PEX piping to 3/4" manifold ports
• Domestic hot and cold water distribution systems
• Underfloor heating manifold connections
• Repairing or retrofitting manifold assemblies

Key specifications

• Connection A: 16 x 2 mm pipe (suitable for PERT/PEX materials)
• Connection B: 3/4" threaded male/female interface for manifold or valve
• Type: mechanical coupling for plumbing distribution
• Application: heating and potable water distribution systems
• Design: compact form factor for manifold assemblies and tight spaces

How to use

Prepare the 16 x 2 mm pipe by cutting it squarely and deburring the inner and outer edges. Insert the pipe fully into the coupling until it reaches the stop, then engage the 3/4" threaded side with the corresponding manifold or valve by hand, finishing with an appropriate wrench to the manufacturer’s recommended torque. Ensure proper alignment and verify the connection by pressurizing the system and inspecting for leaks. Follow standard plumbing installation practices and local regulations during fitting and testing.

Usage recommendations

Use with compatible 16 x 2 mm PERT/PEX pipe and standard 3/4" manifold or valve threads. Confirm material compatibility and follow pressure and temperature limits of the overall system components. If uncertain, consult product documentation or a qualified installer to ensure correct installation and long-term reliability.
