Drain/waste/vent pipe fitting GEBERIT 20605 — 45° bend, 48 mm length, 25 mm width

GEBERIT 20605 is a compact drain/waste/vent pipe fitting with a 45° bend, 48 mm length and 25 mm width. It is designed to provide a short-radius angled joint for redirecting wastewater or vent lines in plumbing systems where space is limited. The fitting is intended for installation in residential and commercial drainage assemblies that require a precise, small-offset change of direction.

Advantages

The 45° geometry allows smoother flow transition compared with sharper angles, reducing the risk of blockages at the offset. Its compact 48 mm length and 25 mm width make it suitable for tight installation spaces and repair work without the need for major reconfiguration of existing pipes. The fitting is manufactured to fit standard drainage systems and facilitates straightforward connection and alignment during assembly.

Suitable for

• Redirecting drain or vent lines in confined installation spaces
• Repairs and modifications of existing plumbing where a small-angle offset is required
• Residential and commercial wastewater drainage systems
• Areas where a compact 45° connection reduces impact on surrounding structures

Key specifications

• Bend angle: 45°
• Overall length: 48 mm
• Nominal width: 25 mm
• Application: drain / waste / vent connections
• Use: short-radius offset in plumbing assemblies

How to use

Select the fitting at the correct orientation to achieve the required offset and prepare the mating pipe ends according to the piping system’s installation guidelines. Insert the fitting into the corresponding socket or joint, ensuring a secure seat and alignment with adjacent pipes. Complete any required sealing or fastening steps consistent with the system type (e.g., solvent welding, compression, or rubber-socket connection) and verify the joint for correct fit and rotation before finalizing the installation.

Usage recommendations

Confirm compatibility with the existing drainage system materials and dimensions before installation. For installations in concealed or load-bearing areas, ensure access panels or serviceability is maintained. Perform a leak test after assembly and follow local plumbing codes and manufacturer guidance for sealing and support.
