SiGMA-Li elbow socket PP 32 mm 90° BOR Plus (KN9032)

SiGMA-Li elbow socket PP 32 mm 90° BOR Plus (KN9032) is a polypropylene 90-degree socket fitting designed for creating right-angle connections in 32 mm pipe systems. Intended for non-pressurized plumbing such as drainage, waste and vent installations, this elbow provides a compact change of direction while maintaining a smooth internal passage for reliable flow. The fitting is compatible with systems that use solvent-weld or push-fit connections depending on the overall system design.

Advantages

The polypropylene construction ensures chemical resistance and long-term dimensional stability in typical residential and light commercial drainage environments. The 90° socket geometry offers a compact elbow with a smooth internal radius to minimize flow turbulence and blockages. The BOR Plus variant is manufactured to consistent dimensions for straightforward alignment and secure joining in compatible 32 mm pipe runs.

Suitable for

• Drainage and waste piping in residential buildings
• Vent stacks and soil pipe layouts
• Light commercial non-pressurized plumbing
• Right-angle direction changes in 32 mm PP systems

Key specifications

• Material: polypropylene (PP)
• Nominal pipe size: 32 mm
• Angle: 90 degrees
• Connection type: socket for solvent-weld or push-fit compatible systems
• Application: non-pressurized drainage, waste and vent

How to use

Prepare pipe ends by cutting square and deburring to ensure full insertion into the socket. For solvent-weld systems, apply the recommended primer and solvent cement to both pipe and socket surfaces, insert the pipe fully and hold until the joint sets according to the adhesive manufacturer's instructions. For push-fit-compatible systems, follow the system supplier's installation guidelines: push the pipe into the socket until it reaches the stop and confirm a secure mechanical engagement. Ensure proper slope for drainage runs and allow adhesive joints to cure before testing the system.

Usage recommendations

Use the fitting only in non-pressurized drainage, waste and vent applications. Match the fitting to the correct 32 mm PP pipe type and follow local plumbing codes. Avoid exposure to direct sunlight for prolonged periods and do not use the fitting in pressurized supply lines or where chemical compatibility has not been verified.
