TECE transition elbow 90° brass 20 mm x 3/4" for plumbing connections

TECE transition elbow 90° brass 20 mm x 3/4" is a right-angle fitting designed to join a 20 mm pipe end with a female 3/4" threaded connection. Manufactured in brass to meet requirements of domestic and commercial plumbing, this elbow enables a secure transition between press or soldered 20 mm pipe systems and threaded fittings, valves or appliances. It is suitable for potable water and heating circuits where a compact, 90-degree change of direction and a reliable threaded interface are needed.

Advantages

The brass construction ensures corrosion resistance and long service life while maintaining mechanical strength under typical plumbing conditions. The 90° geometry provides a compact footprint for space-restricted installations. The female 3/4" thread offers compatibility with common threaded valves and fixtures, and the 20 mm connection supports standard pipe installation methods. The design simplifies transitions between different connection types and helps reduce leak points when installed correctly.

Suitable for

• Connecting 20 mm pipe ends to appliances, valves or fittings with 3/4" female threads
• Potable water supply lines in residential or commercial buildings
• Heating circuits where a right-angle transition to a threaded component is required
• Tight or concealed installation spaces requiring a compact 90° elbow

Key specifications

• Material: brass
• Connection A: 20 mm pipe end (for press, solder or compatible joint)
• Connection B: female 3/4" thread
• Angle: 90°
• Application: potable water and heating circuits

How to use

Prepare the 20 mm pipe end according to the chosen joining method (cut square, deburr and clean for press or soldering). Install the elbow by connecting the 20 mm end with the appropriate joining technique and engage the female 3/4" thread with the mating male threaded component, applying thread sealant or tape where required by local practice. Tighten to the manufacturer-recommended torque values for threaded plumbing connections and check alignment to avoid stress on the pipework. After installation, pressure-test the system in accordance with applicable standards to verify leak-free operation.

Usage recommendations

Use compatible thread sealants approved for potable water when connecting to the 3/4" thread. Verify material compatibility and installation method for the 20 mm pipe (press, solder, or other) before assembly. Avoid overtightening to prevent thread or fitting damage and follow local plumbing codes and pressure-testing procedures to ensure safe operation.
