Description The Land Drainage Coupler 160mm is a straight connector fitting designed to join two 160mm land drainage coils in-line. It is used in large-scale drainage systems where wide-diameter pipes are required for managing high volumes of surface water — including paddocks, fields, sports turf, and large landscape projects. This coupler is used during trench-based installation to connect two coil ends securely, maintaining a smooth flow of water through the system. Its simple cylindrical design slides over the external ribs of the 160mm land drain coils, allowing for quick and practical joining without the need for adhesives or complex fittings. It is most commonly used when extending existing 160mm drainage runs or repairing damaged sections within a coil layout. The fitting is suitable for use with standard 160mm single-wall land drain coils used in soft-ground or agricultural environments. Designed for reliability and ease of use, this coupler supports consistent water management across the system without flow disruption or restriction. It can be installed by hand during trench works and is fully compatible with 160mm land drainage fittings such as junctions, end caps and silt traps. • Large-Diameter Joiner: Designed for 160mm land drain coils • Inline Connection: Joins two coils for longer drainage runs • Simple Fit: Slides over corrugated pipe ends • Installation Use: Buried in trench systems for soft ground • System Compatibility: Works with standard 160mm fittings Specifications • Size: Fits 160mm outer diameter land drain coils Applications • Paddock and equestrian land drainage • Agricultural and field coil connections • Turf and racecourse drainage systems • Extending or repairing 160mm land drain runs • Large-scale soakaway or sub-surface installations Why Choose Stanley John LTD Stanley John LTD is based in Newbury, Berkshire and supplies quality land drainage systems across Berkshire, Hampshire, Wiltshire, Oxfordshire, Surrey, Greater London and surrounding counties.
