Ordering Instructions

          The complete Part Number tells us exactly what assembly you want. For example, let's say that you want to order a Mark 1 Adjustable Nozzle Assembly to fit onto a 32 mm (1 1/4") pipe, with a Single Spring, and with a 65° Flat Spray Nozzle Tip that will deliver 13 lpm at 2.0 bar:




          Note: Our standard Nozzle Assemblies are designed with spigots to fit risers with 17 mm diameter holes. We also manufacture assemblies with smaller spigots for 14 mm diameter holes and larger spigots for 20 mm holes. To specify the 14 mm spigots, simply change the ‘UNI’ in the part number to ‘SS’ for Small Spigot or LS for Large Spigot. For a Small Spigot, using the example above, the part number would become: SS 150 6540 M1.
