Brass transitional nipple TECE 25 mm x 3/4" male (model 705507)

Brass transitional nipple TECE 25 mm x 3/4" male is a compact metal fitting designed to join 25 mm piping to a 3/4" male threaded connection. Manufactured from brass, the nipple provides a durable and corrosion-resistant interface for domestic and commercial plumbing systems. It is intended for use where a secure threaded transition is required between plastic or copper piping and standard threaded fittings.

Advantages

This transitional nipple offers reliable mechanical strength and good resistance to corrosion due to its brass construction. Its compact form factor simplifies installation in confined spaces and ensures a stable threaded connection that tolerates normal thermal expansion in water and heating systems. The metal-to-thread interface reduces the need for soldering or complex adaptors, enabling faster repair and retrofit operations.

Suitable for

• Connecting 25 mm plastic or metal pipe to a 3/4" threaded fitting
• Domestic and commercial water supply installations
• Heating circuits and radiator connections requiring a threaded transition
• Repair, replacement and retrofit plumbing work

Key specifications

• Material: brass
• Pipe connection dimension: 25 mm
• Thread type: 3/4" male
• Application: potable water and heating systems
• Design: transitional nipple for pipe-to-thread connections

How to use

Prepare the 25 mm pipe end according to the pipe material: deburr and, if required, clean and apply appropriate sealant for the pipe type. Thread the 3/4" male end into the mating female threaded fitting using suitable tools, taking care not to overtighten which can damage threads or fittings. For plastic pipes, follow manufacturer recommendations for retention methods; for metal pipes ensure a proper fit and sealing method is used. After installation, pressurize the system and inspect the connection for leaks.

Usage recommendations

Use compatible thread sealant or tape suitable for water and heating systems and follow local plumbing codes. Verify material compatibility with system media and temperature limits. For high-temperature or high-pressure applications consult system specifications and use appropriate fittings rated for those conditions.
