VESBO reducing tee 63/25 PP-R plumbing fitting, polypropylene-random connection

Reducing tee VESBO 63/25 made of polypropylene-random (PP‑R) is a plumbing fitting designed to create a branch from a 63 mm main run to a 25 mm secondary line. The fitting is intended for use in hot and cold water distribution, central heating circuits and other pressure pipeline applications where corrosion resistance, smooth internal surfaces and reliable welded joints are required. The connection type is suitable for thermal fusion (socket fusion) joining with PP‑R pipes to ensure a homogeneous, leak‑resistant system.

Advantages

The VESBO reducing tee offers long service life due to the chemical stability of PP‑R and resistance to corrosion and scaling. Its smooth internal surface reduces flow resistance and facilitates hygienic water transport. Designed for fusion welding, the fitting provides strong, permanent joints that withstand system pressure and temperature variations typical in plumbing and heating networks. The dimensional transition from 63 mm to 25 mm allows easy integration of smaller branches without additional adapters.

Suitable for

• Hot and cold potable water distribution systems
• Central heating circuits and radiators
• Domestic and commercial plumbing installations requiring a reduced branch
• Pressure pipelines where PP‑R fusion welding is used

Key specifications

• Material: polypropylene‑random (PP‑R)
• Connection method: thermal fusion (socket fusion) compatible
• Main outlet diameter: 63 mm
• Branch outlet diameter: 25 mm
• Application: pressure pipeline for hot and cold water, heating circuits
• Internal surface: smooth, low roughness to reduce flow resistance

How to use

Prepare pipe ends by cutting square and removing burrs, then mark the insertion depth. Use a socket fusion welding tool sized for PP‑R fittings and pipes. Heat both the fitting socket and pipe end to the recommended temperature, insert the pipe to the marked depth and hold in position until the joint cools and solidifies. Ensure alignment during cooling and follow the fusion tool manufacturer’s instructions for heating time and pressure. After welding, pressure test the assembled system according to applicable standards before commissioning.

Usage recommendations

For durable results, store fittings protected from direct sunlight and extreme temperatures prior to installation. Use certified PP‑R welding equipment and appropriate personal protective equipment. Observe system design limits for operating pressure and temperature, and perform routine inspections after installation to verify joint integrity.
