Pipe adapter Supratherm 20x3/4" M – PP‑R male threaded transition fitting

Supratherm PP‑R pipe adapter 20 x 3/4" M is a polypropylene‑random (PP‑R) male threaded transition fitting designed to connect 20 mm PP‑R piping to 3/4" female threaded components. The adapter is lightweight, corrosion‑resistant and suitable for use in potable water, heating and cooling systems where PP‑R piping is used, and is rated for service temperatures up to 90°C.

Advantages

The PP‑R transition fitting offers high impact and abrasion resistance along with chemical resistance inherent to PP‑R material. Its male threaded metal-compatible end enables secure connection to 3/4" female threaded fittings or valves, while the socket end is designed for reliable heat-fusion to 20 mm PP‑R pipe. The product simplifies transitions between plastic piping and threaded components and reduces the risk of corrosion compared with all-metal fittings.

Suitable for (tasks / use cases)

• Connecting 20 mm PP‑R pipes to 3/4" female threaded valves or fittings
• Domestic hot and cold potable water systems
• Heating circuits and radiator connections
• Air conditioning and industrial process piping where PP‑R is specified

Key specifications

• Brand: Supratherm

How to use

Prepare the 20 mm PP‑R pipe by cutting it square and cleaning the outer surface. Join the socket end of the adapter to the PP‑R pipe using the appropriate heat fusion (socket welding) method and tools for PP‑R materials, following the pipe system manufacturer's instructions. After cooling, thread the 3/4" male end into the corresponding female threaded component using appropriate sealing (e.g., PTFE tape) if required. Verify tightness and correct alignment before putting the system into service.

Usage recommendations

Use only approved PP‑R welding equipment and follow local plumbing codes. Do not exceed the adapter's rated temperature. For potable water and heating applications, ensure compatibility of threaded components and apply suitable thread sealant where specified.
