Transition fitting Supratherm PPR 25x3 to 3/4" female, PP-R to female threaded connection

Supratherm transition fitting for joining PP‑R pipe (25 x 3 mm) to a 3/4" female threaded component. The fitting connects polypropylene-random (PP‑R) piping to fixtures or components with a 3/4" female thread and is intended for use in hot and cold water systems, heating and air conditioning circuits, and general plumbing repairs or retrofits. The product is compatible with standard PP‑R welding (socket fusion) and threaded assembly methods.

Advantages

The PP‑R transition fitting is lightweight while providing high impact, wear and chemical resistance. It is rated for continuous operation at temperatures up to 90°C and creates a secure interface between plastic PP‑R piping and threaded metal or plastic components. The threaded female connection simplifies integration with standard fixtures and reduces the need for additional adaptors.

Suitable for

• Joining PP‑R pipe (25 x 3 mm) to 3/4" female threaded valves or fittings
• Hot and cold water supply lines
• Heating and air conditioning circuits
• Plumbing repairs and retrofits where a threaded interface is required

How to use

Prepare the PP‑R pipe by cutting it square and cleaning the insertion end. Join the PP‑R side using the appropriate socket fusion welding tool and technique for 25 x 3 mm pipe, following the welding tool manufacturer’s instructions. After cooling, assemble the 3/4" female threaded side to the mating threaded component using suitable thread sealant or tape as required. Ensure all connections are tightened to the recommended torque and pressure-tested before putting the system into regular service.

Usage recommendations

Use compatible PP‑R welding equipment and follow local plumbing codes. For threaded joints, use thread sealant or PTFE tape designed for potable water and heating systems. Do not exceed the specified maximum operating temperature and ensure the fitting is installed in accessible locations for inspection and maintenance.
