Double-Socket Coupler MAGNAPLAST KG-ERMM 200 SN8 — 200 mm PVC-U sewer pipe connector

MAGNAPLAST KG-ERMM 200 SN8 is a double-socket PVC-U coupler designed for joining 200 mm sewer pipes in underground drainage systems. Intended for KG gravity sewer and stormwater installations, the 200 mm two-bell connector provides a rigid, aligned joint between compatible KG sewer pipes and is manufactured to meet the SN8 ring stiffness requirement for stable load-bearing performance in buried applications.

Advantages

The product offers a simple mechanical connection that maintains pipe alignment and resists deformation under typical soil and traffic loads due to its SN8 stiffness rating. Its PVC-U construction ensures chemical resistance, low weight for easier handling on site, and long-term durability in non-pressure sewer and stormwater networks. The double-socket design allows insertion of plain-ended pipes from either side to form a continuous run without additional coupler parts.

Suitable for

• Gravity sewer lines with 200 mm KG pipes
• Stormwater drainage and surface runoff systems
• Civil and municipal non-pressure underground drainage projects

Key specifications

• Material: PVC-U (rigid unplasticized polyvinyl chloride)
• Connection type: double-socket (two-bell) coupler
• Nominal pipe size: 200 mm
• Stiffness class: SN8 (ring stiffness for buried applications)
• Application: non-pressure sewer and stormwater drainage

How to use

Prepare plain-ended 200 mm KG pipes by cleaning mating faces and removing debris. Ensure pipes are cut square and chamfered if required by applicable installation standards. Apply compatible lubricants to socket sealing surfaces if the joint design includes elastomeric seals, then insert pipe ends into each socket until proper insertion depth is reached. Check alignment and axial spacing before backfilling. Follow local codes and manufacturer guidelines for bedding, compaction, and joint testing where applicable.

Usage recommendations

Use MAGNAPLAST KG-ERMM 200 SN8 in accordance with local installation standards for buried non-pressure drainage. Select appropriate bedding and compaction to support the pipe and avoid point loads. Verify compatibility of sealing elements and lubricants with PVC-U materials, and inspect completed joints before and after backfilling.
