Description

Enabling smooth transitions between different pipe diameters, this press fit plain reducer is an essential component for system design and flow management. It allows installers to adapt pipework layouts efficiently without compromising system integrity or performance. Manufactured from 316L stainless steel, it provides excellent resistance to corrosion and is well suited to demanding commercial and industrial environments. The robust construction ensures long term durability, even under varying pressures and temperatures.

The M-profile press connection ensures compatibility with standard press tools, allowing for a fast and consistent installation process. The plain sigot end acts as a small section of pipe that can be inserted into another press fitting, with no need for welding or threading. Installation is safer and more efficient, reducing both labour time and on-site risks. An EPDM seal (FKM alternative available) delivers reliable performance across a wide operating range, while the integrated leak detection feature ensures any unpressed joints are clearly identified during pressure testing. This helps maintain confidence in the system before it is brought into operation.
