External sewer elbow 87° MAGNAPLAST 160 mm model 22140

External sewer elbow MAGNAPLAST 160 mm model 22140 with an 87° bend is a PVC fitting designed for outdoor drainage and sewer systems. The elbow provides a near-right-angle change of direction for 160 mm diameter pipes, enabling connection between run and discharge lines in stormwater, surface drainage and external wastewater routing applications. The product is intended for gravity flow systems and for use where a durable plastic connection resistant to corrosion and common sewage conditions is required.

Advantages

The elbow is manufactured from weather-resistant PVC, which ensures long service life in external installations and reduces maintenance compared with metal alternatives. Its 87° curvature facilitates smoother flow than a sharp 90° corner, reducing the risk of blockages and minimizing hydraulic losses. The dimension and shape are compatible with standard 160 mm sewer pipe systems, allowing straightforward installation and reliable sealing when used with appropriate gaskets or solvent-weld techniques.

Suitable for

• External wastewater drainage and sewer discharge lines
• Stormwater runoff systems and surface drainage
• Connection of 160 mm diameter PVC sewer pipes at near-right angles
• Gravity-flow drainage networks in residential, commercial or municipal settings

Key specifications

• Material: PVC suitable for external drainage use
• Bend angle: 87 degrees for near-right-angle direction change
• Nominal diameter: 160 mm
• Application: external sewer and stormwater systems, gravity flow
• Compatibility: designed to mate with 160 mm sewer pipe systems and fittings

How to use

Position the elbow between the two sections of 160 mm pipe where a near-right-angle turn is required. Prepare the pipe ends according to the chosen jointing method — clean and deburr for solvent-weld connections or ensure gasket surfaces are free of dirt if using rubber seals. Insert the pipes into the elbow sockets and apply the appropriate joining technique (solvent cement or gasket compression) following manufacturer instructions for pipe and seal materials. Ensure correct alignment and slope for gravity flow before completing the joint and allow any adhesive or sealant to cure as recommended.

Usage recommendations

Use this PVC elbow in outdoor drainage systems where corrosion resistance and ease of installation are priorities. Verify compatibility with local sewer standards and pipe types, support adjacent pipe runs to prevent undue stress on the fitting, and avoid exposure to concentrated solvents or temperatures outside the PVC operating range. Periodic inspection for blockages and secure joints will help maintain reliable operation.
