Identify your poly pipe inner diameter (typically 3/4", 1", 1.25", 1.5" or 2" for rural systems) and select the matching HW-375 fitting size. For barb connections, slide the pipe onto the barb and secure with two stainless steel clamps, tightening evenly on both sides. For threaded connections, wrap thread tape around the male thread and hand-tighten before using a spanner for final tightening. Ensure all connections are secure before pressurising the system. Tips: Always use stainless steel clamps with barb fittings to prevent corrosion and ensure a lasting seal in Queensland's climate. Test your system at low pressure first to check for leaks before full operation, and regularly inspect connections for wear, especially in pump-fed systems running above 600kPa.
