Flexible connector PLASTBRNO H50/K50 40 mm, length 1000 mm

Flexible connector PLASTBRNO H50/K50 40 mm, length 1000 mm is a corrugated plastic coupling designed for universal use in drainage and ventilation installations. With an overall length of 1000 mm and a DN50 sleeve combined with a DN40 transition, the connector allows connection between pipes of different diameters and provides flexibility for installation in confined or irregular spaces. Made of durable grey plastic, it is suitable for household wastewater systems and for situations requiring a sealed, adaptable joint.

Advantages

The corrugated design ensures axial and angular flexibility, enabling compensation for misalignment and minor movements while reducing transmission of vibration and noise. The integrated DN50 sleeve and DN40 transition eliminate the need for extra adapters when connecting H50 and K50 fittings. Its 1000 mm length offers extended reach for longer runs or more complex configurations. The material is resistant to typical household wastewater conditions and supports reliable, watertight installation.

Suitable for

• Connecting H50 and K50 drainage or ventilation pipes
• Installations with limited space or non-linear layouts
• Repair work where flexible compensation of misalignment is needed
• Systems requiring vibration and noise reduction between pipe sections

Key specifications

How to use

Insert the DN50 sleeve over the corresponding pipe end and position the DN40 transition onto the smaller pipe or fitting. Adjust the corrugated section to accommodate alignment and required orientation, then secure connections according to the pipe system’s standard fixing method (clamps or sealing rings as applicable). Ensure ends are fully seated to maintain a watertight joint and verify the assembled run for proper slope and support.

Usage recommendations

For long-term performance, avoid sharp bends that could overstress the corrugations, provide adequate support along the 1000 mm length to prevent sagging, and use compatible clamps or sealing rings recommended for H50/K50 systems. Not intended for high-pressure applications; use only in gravity drainage or ventilation systems as specified.
