Product Overview
The complete set of colour-coded metering tips for the high pressure Hydro-Force AS08 injection sprayer. Swapping the tip changes the dilution the sprayer draws, so one sprayer covers presprays, deodorisers, tile and grout solutions and protectors without mixing anything by hand.
A Hydro-Force sprayer leaves the factory with one tip fitted. This kit is what makes the ratio adjustable.
Important — High Pressure Kit
This is the high pressure kit. The factory ratio on a high pressure Hydro-Force is 1:8; on a low pressure Hydro-Force it is 1:4. The two sprayers use different metering tips, so check which machine you have before ordering.
CCW does not currently stock the low pressure kit. If yours is the low pressure sprayer, contact us before ordering.
How the Ratio Is Actually Determined
The tip sets the ratio, but it does not set it alone. Two things move it in normal use:
- Line pressure. Higher pressure draws proportionally less chemical, so the mix gets weaker. Lower pressure draws more, and the mix gets stronger. The same tip at 300 psi and at 900 psi will not give you the same dilution.
- Chemical viscosity. The published ratios assume a concentrate about as thick as water. A heavier concentrate draws more slowly and dilutes further than the tip suggests.
Water temperature moves it slightly as well, though not usually enough to matter.
The practical consequence: choose the tip for the ratio you want at the pressure you actually run, not at the pressure on the label.
Changing a Tip
Remove the clear tube at the bottom of the injection valve, then unscrew the metering tip anticlockwise. Fit the new tip, refit the tube, and check the draw on clean water before you put chemical through it.
Individual Tips Stocked Separately
If you only need one ratio, CCW stocks two of the tips on their own:
The kit is the better buy if you change chemistry between jobs. A single tip is the better buy if you have settled on one ratio and want a spare.

Hydro-Force publishes the ratios against a pressure chart rather than as fixed figures. Tell us the ratio you want and the pressure you run and we will tell you which tip to fit.
Operating Advice
- Keep the tips together. They are small, colour-coded and easily lost individually, and a kit missing three tips is not a kit.
- Flush the sprayer with clean water after solvent-bearing chemistry, before the tip is changed rather than after.
- Check the strainer when a ratio looks wrong. A partly blocked strainer starves the draw and reads as the wrong tip — see Mesh Strainer without Check Valve (NA0803).
- Do not chase a ratio by changing tips repeatedly. Confirm your working pressure first, then choose once.
Frequently Asked Questions
Will it fit the low pressure Hydro-Force?
No. That sprayer uses different tips and runs a 1:4 factory ratio. Contact us before ordering.
Why is my dilution not what the tip says?
Most often line pressure. Higher pressure gives a weaker mix than the nominal ratio. Thick concentrates do the same.
Do I need the kit if I only use one chemical?
No. Buy the single tip for that ratio and keep a spare.
How do I change a tip?
Remove the clear tube under the injection valve and unscrew the tip anticlockwise.
Can I use it with any concentrate?
Any concentrate the sprayer is suited to. Remember that viscosity affects the draw, so a thick concentrate will dilute further than the tip's nominal figure.

What We See in the Field
Dilution complaints on injection sprayers are usually pressure complaints wearing a different hat. Before condemning a tip or the valve, find out what pressure the machine is actually delivering at the sprayer — the ratio follows from that, and no tip will correct for a machine running well above or below where the chart assumes.
