TECE TECEflex alternative heating pipe connection GW 3/4 x 16, model 740136

TECE TECEflex alternative heating pipe connection GW 3/4 x 16, model 740136, is a mechanical fitting designed to join 16 mm plastic heating pipes with a 3/4" female threaded outlet. It creates a compact, reliable transition between push-fit or compression-style pipe systems and threaded radiator or manifold connections, ensuring a sealed interface suitable for hydronic heating installations.

Advantages

This fitting combines a small installation footprint with mechanical robustness and compatibility with standard 3/4" female threaded outlets. Its design provides leak-resistant performance when installed correctly, simplifies the connection of 16 mm heating pipes to threaded components, and reduces the need for complex adapters or additional sealing operations. The fitting is suitable for both new installations and retrofit work where a threaded transition is required.

Suitable for

• Connecting 16 mm heating pipes to radiators with 3/4" female threaded inlets
• Linking heating manifolds or distribution units to 16 mm pipe circuits
• Retrofit work where a threaded-to-pipe transition is needed
• Compact installations in tight spaces behind covering panels or within cabinets

Key specifications

• Connection type: 16 mm pipe to 3/4" female thread
• Application: hydronic heating systems (radiators, manifolds, branches)
• Compatibility: designed for 16 mm plastic heating pipes
• Installation: mechanical fitting for straightforward assembly
• Form factor: compact transition fitting suitable for confined spaces

How to use

Ensure the pipe end is cut square and deburred, then insert the 16 mm heating pipe fully into the fitting according to the manufacturer's guidance. Tighten the threaded connection to the 3/4" female outlet using appropriate tools and sealing method if specified for the mating component. Pressurize and test the system for leaks following standard commissioning procedures. For retrofit work, isolate and drain the circuit before removing existing fittings and installing the TECEflex connection.

Usage recommendations

Verify material compatibility between the 16 mm pipe and the fitting, follow local plumbing and heating codes, and perform a pressure test after installation. Use recommended installation tools and replacement parts from the same product family to ensure a reliable, long-lasting connection.
