Poly to steel couplings - SDR17 - Female B-Type - Australia | Irrigation, Dewatering & Mining

This Female B-Type galvanised steel coupling is factory-crimped to high-strength ratings for secure connection to poly pipe. Simply weld poly to poly, attach the coupling, and you’re ready for fast, reliable water transfer with far less setup time and effort. Built for rugged Australian conditions, this coupling delivers durability across irrigation, mining, dewatering and construction applications. Designed to connect quickly to a Male B-Type coupling using the lever-ring locking system, and supplied with a fitted seal for dependable water retention and long-term performance.

Applications by Industry 

Agriculture & Irrigation

Use on:

• Travelling irrigators – rapid hose changes and reliable joints when shifting irrigators between paddocks
• Solid-set sprinkler and mainline systems – quick assembly of aluminium or steel mainlines, submains and hydrant risers.
• Pivot and lateral-move systems – connecting pump outlets, booster pumps and drainage points.
• Fertigation / effluent lines – connecting to slurry or effluent spreader systems where robust couplings are required.

Benefits for irrigation

• Fast seasonal setup and pack-down
• Strong, high-flow connection with minimal pressure loss
• Compatible with steel, aluminium, PVC and poly / layflat hose (via Polycrimp and hose-tail versions)

Mining & Quarry Dewatering

Use on:

• Mine pit and highwall dewatering lines
• Tailings dam transfer and return lines
• Sump and drainage pumps feeding long temporary pipelines
• Bypass pumping during maintenance shutdowns

Diameters from 50–450 mm and pressure ratings typically 5–20 bar, ideal for high-flow mine water management.

• mine dewatering hose couplings
• high pressure quick couplings for mining
• galvanised steel couplings for abrasive water

Civil, Construction & Bypass Pumping

Use on:

• Sewer bypass and emergency pumping
• Stormwater diversion and flood control lines
• Wellpoint dewatering around excavations
• Temporary pump manifolds and header systems
