How To Order A Mark I Adjustable Nozzle Assembly:

The complete Part Number tells us exactly what assembly you want. 

For example, let's say that you want to order a Mark I Adjustable Nozzle 

Assembly to t on a 1-1/2 inch pipe, with a single spring, and with a 65° Flat 

Spray Nozzle Tip that will deliver 3.5 gpm at 30 psi:

 

Step 1:

The Part Number begins with 'UNI' and the Pipe Size, as follows:

'UNI 100' = 1 inch pipe

'UNI 125' = 1-1/4 inch pipe

'UNI 150' = 1-1/2 inch pipe

'UNI 200' = 2 inch pipe

 ... so in our example, we would have so far...

'UNI 150 ...'

 

Step 2:

Select a Nozzle Tip from th tip selection page and add the Tip Number to the Part 

Number, so in this example we now have...

'UNI 150 6540...'

Note that the 'UNI' in front of the Tip Number is dropped when 

the Tip Number is incorporated into the Assembly.

 

Step 3:

Add 'M1' to denote the Style, which is standard with Single Spring. If it was to 

have a Double Spring, the Style would be 'M1 D'.

 

So, in our example, we end up with...

'UNI 150 6540 M1'

 

Note: Our standard Nozzle Assemblies are designed with spigots to t risers 

with 21/32" diameter drilled holes. We also manufacture assemblies with 

smaller spigots for 9/16" diameter holes. To specify the 9/16" spigots, simply 

change the 'UNI' in the part number to 'SS' for 'Small Spigot'. In that case, 

using the example above, the part number would become...

 

'SS 150 6540 M1'
