Brass Tece coupling with internal thread 25 x 3/4" - plumbing fitting

TECE brass coupling with internal thread 25 x 3/4" is a plumbing fitting designed to connect a 25 mm pipe to a 3/4" threaded component. Manufactured from brass, the coupling offers corrosion resistance and mechanical strength for use in water installations, heating systems and sanitary equipment. The fitting creates a sealed transition between a smooth or press-fitting 25 mm pipe end and a 3/4" female thread, enabling integration with valves, taps, appliances and threaded piping components.

Advantages

The brass construction provides durability and resistance to corrosion in potable water and heating applications. The internal 3/4" thread allows straightforward connection to standard threaded components without the need for adapters, while the 25 mm end is compatible with common plumbing pipe joining methods. The coupling's compact design saves space in installation areas and delivers a reliable mechanical seal when installed according to standard plumbing practice.

Suitable for

• Connecting 25 mm copper, PEX or multi-layer pipes to 3/4" threaded valves or fixtures
• Domestic hot and cold water supply systems
• Radiator and heating circuit connections requiring a 25 mm to 3/4" transition
• Sanitary installations where a threaded appliance or tap must be joined to a 25 mm line

Key specifications

• Material: brass (corrosion-resistant plumbing alloy)
• Connection types: 25 mm pipe end to 3/4" internal (female) thread
• Application: potable water, heating and sanitary systems
• Design: compact coupling for mechanical threaded connection
• Operating environment: indoor plumbing and heating installations

How to use

Prepare the 25 mm pipe by cutting squarely and deburring the end. Fit the pipe end to the coupling according to the pipe system requirements (press, solder, or push-fit) and ensure a secure mechanical joint. Engage the 3/4" threaded component into the internal thread of the coupling using appropriate thread sealant or tape if required by the installation standard. Tighten to the recommended torque for the threaded connection and check for leaks under normal system pressure before finalizing insulation or concealment.

Usage recommendations

Use only with compatible 25 mm piping materials and standard 3/4" threaded fittings. Observe local plumbing codes and manufacturers' instructions for sealing methods and torque values. Inspect the coupling periodically for signs of wear or corrosion in aggressive environments and ensure connections are tested for leaks after installation.
