Brass transition nipple TECE G 20 mm x 3/4" (model 8610105)

TECE brass transition nipple G 20 mm x 3/4" is a plumbing fitting designed to connect 20 mm metric pipes to 3/4" threaded fixtures. Manufactured from brass, the fitting provides corrosion resistance and mechanical strength required for water supply and heating systems. The compact design and standard thread form make it suitable for both domestic and professional installations where a reliable thread-to-pipe transition is needed.

Advantages

The brass construction ensures durability and resistance to corrosion in typical potable water and central heating environments. The transition nipple offers a secure threaded connection and stable compression at the metric pipe interface, reducing the risk of leaks when installed correctly. Its standardized dimensions allow compatibility with common 20 mm pipe systems and 3/4" threaded valves or fixtures.

Suitable for

• Connecting 20 mm metric water pipes to 3/4" threaded valves, faucets or fittings
• Domestic water supply installations in kitchens, bathrooms and utility rooms
• Heating system connections where a threaded transition is required
• Professional plumbing and renovation projects requiring metric-to-imperial adaptation

Key specifications

• Material: brass for corrosion resistance and mechanical strength
• Connection A: 20 mm metric pipe interface
• Connection B: 3/4" external thread for standard fittings
• Intended media: potable water and heating fluids
• Typical applications: water supply and heating installations

How to use

Prepare the 20 mm pipe end according to the pipe system requirements (cut square, deburr, and clean). Apply appropriate sealing method for the threaded connection if required by the installation practice (for example, PTFE tape or approved thread sealant) and tighten the 3/4" threaded side to the mating fitting following recommended torque values to avoid overstressing the thread. Ensure the pipe connection is properly secured and any compression or fitting element is installed per the pipe manufacturer's instructions. After assembly, pressure-test the system to verify leak-free performance before commissioning.

Usage recommendations

Use with potable water and heating systems within the manufacturer's specified temperature and pressure ranges. Do not overtighten threaded joints; follow standard plumbing torque guidance. For installations involving aggressive water chemistry or unusual temperatures, verify material compatibility and consult applicable standards or a qualified plumber.
