Standard uPVC 4-Inch Waste Bend, 90-Degree, Solvent Weld

uPVC 90-Degree Waste Bend

The Standard uPVC 4-Inch Waste Bend provides a reliable 90-degree change in direction for gravity-fed drainage systems. This fitting handles high-volume discharge in residential and commercial soil stacks. It is manufactured to interface seamlessly with standard 110mm exterior diameter piping used across Kenyan construction sites.

Built for the Job

Site supervisors and plumbers specify this component for underground and above-ground waste management. The interior wall features a smooth bore finish to minimize the risk of sediment buildup or blockages in horizontal-to-vertical transitions. Its rigid construction ensures the fitting maintains its structural integrity under the weight of backfill or within concrete encasements. Plumbers typically deploy this unit in main soil stacks where a sharp but controlled turn is required to route effluent toward the septic tank or municipal sewer line.

• Connecting toilet waste outlets to vertical soil stacks.

• Routing main drainage lines around foundation footings.

• Installing vent pipe offsets in multi-story buildings.

Product Highlights

High-Grade uPVC Composition

The unplasticized polyvinyl chloride material resists corrosion from household chemicals and acids found in wastewater.

Precision Socket Depth

• Deep socket design allows for maximum surface area contact during solvent welding.
• Tight tolerances ensure a leak-proof interference fit before adhesive application.

Technical Specifications

What’s Included

• 1 x 4-Inch 90-Degree uPVC Waste Bend (Solvent Socket)

On-Site & Workshop Notes

• Always deburr the pipe ends and clean the socket interior with a dedicated pipe cleaner before applying solvent cement.

• Ensure the fitting is fully seated in the socket; hold the joint for 30 seconds to prevent the pipe from backing out during the initial set.

• This component is designed for gravity drainage and should not be used in pressurized water supply lines.

• Store away from direct sunlight for extended periods to prevent UV degradation before installation.
