PVC Drainage Coupler Double Socket

PVC drainage coupler double socket provides a secure socket-to-socket connection between two plain-ended underground pipes. Manufactured from rigid uPVC for long-term structural stability, the coupler supports underground foul and surface water networks. Smooth internal bore maintains hydraulic efficiency, while integrated seals provide watertight performance under typical ground movement.

High-impact uPVC construction resists soil chemicals, moisture, and installation stresses. Compatible with standard SN4 and SN8 underground drainage layouts. Suitable for system repairs, extensions, and alignment corrections without requiring pipe replacement.

Installation Guide:

• Excavate area and clean pipe ends.

• Deburr edges and ensure pipes are cut square.

• Apply silicone-free pipe lubricant to both sockets.

• Insert first pipe fully into socket until seated.

• Align and insert second pipe, maintaining straightness.

• Ensure sealing rings sit evenly for leak-free joints.

• Backfill with granular material, compacting in layers.
