MAGNAPLAST Kolano 15° KGB external sewer elbow 250 mm (24100)

MAGNAPLAST Kolano 15° KGB external sewer elbow 250 mm is a rigid drainage fitting designed for outdoor sewer runs in KGB systems. The 15° angle creates a gentle change of direction that helps align external pipelines, avoid obstacles and preserve hydraulic performance. Made for use with compatible KGB pipes and accessories, this 250 mm elbow is intended for above-ground or shallow-buried drainage segments where a small offset is required.

Advantages

This external sewer elbow provides a controlled, low-angle deviation that minimizes flow disturbance while enabling precise alignment of external drainage lines. Its consistent dimensions ensure a snug fit with KGB system components, simplifying installation and reducing the need for on-site modification. The 250 mm diameter supports standard external sewer capacities and the 15° curvature reduces the number of fittings needed when gradual direction changes are preferred.

Suitable for

• Outdoor sewer runs in KGB drainage systems
• Connecting pipe sections to route around small obstacles
• Aligning pipelines where a minor directional change is required
• Shallow-buried or above-ground external drainage segments

Key specifications

• Angle: 15° bend for gentle directional change
• Nominal diameter: 250 mm external sewer fitting
• Type: external elbow for KGB drainage systems
• Application: outdoor drainage and sewer pipeline routing
• Material characteristics: rigid fitting suitable for external sewer use

How to use

Position the 15° elbow between compatible KGB pipe sections so the curvature provides the required alignment. Ensure pipe ends are clean and free of debris before assembly. Follow the KGB system joining method — typically insertion with sealing elements or solvent/weld methods as applicable to the specific pipe material. Verify the elbow orientation and slope to maintain correct flow direction and fall. After installation, inspect joints for proper sealing and secure support to avoid stress on the fitting.

Usage recommendations

Use the elbow with correctly sized KGB pipes and compatible sealing components; avoid sharp backfilling or point loads directly on the fitting and maintain appropriate bedding and support to preserve alignment and prevent deformation.
