Large Bore Lever Lock Couplings 10" & 12"

Large Bore Lever Lock Couplings (10″ & 12″) offer a robust, quick-connect solution for heavy-duty hose systems. Designed for industrial and agricultural applications, these couplings enable fast, secure connections and disconnections while handling high flow volumes with minimal pressure loss.

• High Flow Capacity
  With 10″ and 12″ diameters, these couplings deliver excellent flow rates, ideal for bulk liquid transfer, dewatering, slurry, or irrigation systems.
• Lever Lock Mechanism
  The lever lock design simplifies assembly and removal — no tools are required. The levers provide positive locking action, helping to relieve stress on the hose and maintain a reliable seal.
• Durable Material Construction
  Often manufactured in galvanised steel (or equivalent robust alloys), these couplings endure corrosion, abrasion, and mechanical wear in demanding environments.

• Versatile End Configurations
  The range includes variants such as:
  • 90° and 45° bends (male × female)
  • Hose tails
  • Flanged male or female ends
  • Weld ends
  • Blank ends
  • O-rings and seals
• Reduced Hose Stress
  By using lever-locked fittings rather than threaded or clamp styles, the coupling helps reduce twisting and torsional stress on hose assemblies.

These large bore couplings are well suited to:

• Dewatering and drainage operations
• Mining, quarrying, and aggregate handling
• Irrigation and agricultural pumping
• Slurry and sludge transfer
• Temporary or modular fluid transfer systems

• Match bore size and flow requirements: Ensure the coupling diameter aligns with hose internal diameter to avoid bottlenecks.
• Check pressure ratings: Choose a coupling whose working pressure exceeds your system demands.
• Consider end connections: Flanged, weld, hose tail or bend ends must match your piping layout.
• Seal & maintenance: Replace O-rings/seals periodically to maintain optimal performance.
• Material compatibility: Confirm the coupling material is compatible with the fluid and environmental conditions (e.g. corrosive media).
