Drain/waste/vent pipe fitting GEBERIT 30102 — 90° bend, 49×29 mm

GEBERIT 30102 is a compact drain/waste/vent pipe fitting with a 90° bend designed for right-angle connections in wastewater and ventilation piping. With external dimensions of 49×29 mm, it enables tight routing of drains and vent lines where space is limited. The fitting is intended for use with standard plastic plumbing systems to facilitate correct alignment and maintain flow direction at a sharp turn.

Advantages

The 90° bend provides a reliable change of direction while keeping the installation footprint small. Its compact size allows placement in confined installation zones behind fixtures or inside service shafts. The fitting is manufactured to meet typical dimensional standards for compatibility with common plastic drain and vent pipes, which simplifies assembly and reduces alignment work during installation.

Suitable for

• Redirecting wastewater lines in bathrooms and kitchens
• Connecting vent pipes in compact installations
• Tight installation spaces behind sanitary fixtures and inside service shafts

Key specifications

• Angle: 90° bend for right-angle piping
• External dimensions: approximately 49 mm × 29 mm
• Application: drain, waste and vent (DWV) systems
• Material: designed for use with standard plastic plumbing materials
• Installation orientation: suitable for horizontal-to-vertical or vertical-to-horizontal changes of direction

How to use

Position the 90° bend at the required junction and ensure compatible pipe ends are clean and free of debris. Align the fitting with the adjoining pipe sections, then connect by the appropriate method for the system (push-fit, solvent weld, or rubber seal), following the pipe and fitting manufacturer’s instructions. Check that the bend provides correct slope and alignment for gravity drainage, and secure the assembly with supports or brackets as needed to prevent strain on joints.

Usage recommendations

Verify pipe diameters and connection types before installation to ensure proper fit. Maintain the recommended slope for drainage and avoid sharp changes in direction immediately upstream of the bend where possible to reduce the risk of blockages. Inspect joints after assembly and perform a leak test according to local plumbing regulations.
