Nozzle holders
The Uni-Spray system has a number of different holders for attaching spray nozzles to riser pipes. The MK1 and 3 designs allow for the adjustment of the direction and orientation of the spray nozzle whilst the MK2 is a fixed nozzle holder.
The nozzle holders are suitable for pipework from 1” to 2” and can accommodate either Uni-Spray ball socket nozzles of various types or threaded nozzles from 1/8” to ½” BSP or NPT thread.
MK1 - Clamp adjustable nozzle holder
A single or double clamp style holder with an adjustable ball socket that can either take a moulded Uni-Spray ball socket nozzle or a male threaded nozzle from 1/8” to ½”.

NEW! MK4 - Threaded nozzle base for "Quik-Change" Tips
![Mark 4 Mark4 Nozzle Base for Quik-Change nozzles](/images/default-source/e-mail-images/mark-4-no-header.jpg?sfvrsn=b4f0f092_0)
The Mark 4 “Quik-Change” Nozzle Base from Uni-spray was designed for printed circuit board (PCB) washing but lends itself to any wash type usage where adjustment/orientation other than straight ahead is not required and space may be limited.
The Mark 4 is directly threaded into pipework and with a bayonet quarter turn connection the system can accept any of Uni-spray’s “Quik-Change” nozzle tips. The tips are available in a huge range of spray angles and in flat spray, straight jet, full cone and hollow cone spray patterns.
Made from custom-blended polypropylene or Kynar by special order, the Mark 4 is impervious to most chemicals and has a low-profile design.
