Product Overview
The TCBS is a 12 litre heavy duty pump-up sprayer built specifically for harsh chemistry. It has Viton parts throughout, so it handles solvents as well as water-based products.
All-brass gun, 18 inch brass extension, 40 inch braided chemical hose, brass spray tip, metal pump rod, internal pressure relief valve and a funnel top for filling. Fully rebuildable.
Injection or Pump-Up?
Two different ways to get chemical onto a floor, and the choice comes before the model.
| Injection sprayer | Pump-up sprayer | |
|---|---|---|
| How it works | Runs off your solution line and meters concentrate into the flow | Self-contained, hand pumped, chemical mixed by hand |
| Mixing | Automatic, set by a metering tip | Measured and mixed by the operator |
| Needs | A machine and a hose to the sprayer | Nothing — works anywhere |
| Best for | Volume prespray on a job where the machine is already running | Away from the machine, small areas, and chemistry you would not put through the line |
| Models | AS08 Pro, AS08P Plus | AS202 TWBS, AS16A TCBS, AS14A Budget |
Most operators end up with both: an injection sprayer for prespray volume, and a pump-up for acids, solvents and anything the machine should not see.
Which Pump-Up Sprayer
The deciding question is what chemistry you put through it.
| Sprayer | Capacity | Solvents | Harsh acids | Build |
|---|---|---|---|---|
| AS202 TWBS | 8 L | Viton check valve — ask us for your chemistry | Brass parts present | Brass trigger and extension, rebuildable |
| AS16A TCBS (this product) | 12 L | Yes — Viton throughout | Brass parts present | All-brass gun, metal pump rod, rebuildable |
| AS14A Budget | 12 L | No — water-based only | Best choice — no metal parts | Plastic valve and extension |
The AS14A has no metal parts, which is exactly why it suits harsh acids and exactly why it must not see solvents. The AS16A is the opposite trade: Viton throughout for solvent work, with brass in the fluid path.
If you are running one sprayer for everything, you will eventually damage it. Dedicating a sprayer to acid and another to solvent is cheaper than rebuilding either.
Why Viton Throughout Matters
Solvents swell and soften ordinary seal materials. A sprayer with the wrong elastomers works for a while, then leaks at the pump, the trigger and the hose, and the operator blames the sprayer rather than the chemistry.
Viton is the material specification that lets a sprayer live on solvent work. It is the reason this sprayer costs more than a general purpose one, and the reason it is still working when the general purpose one is not.

Operating Advice
- Release the pressure before opening the tank. A pump-up vessel holds pressure long after the last stroke.
- Dedicate a sprayer to a chemistry type and label it. Cross-contamination between acid and alkaline products is the most common cause of a sprayer that stops working properly.
- Flush it out at the end of the day rather than leaving product in it overnight. Most seal failures start there.
- Check the relief valve as part of servicing — it is the safety component on a pressurised vessel.
- Store it depressurised, with the lid loose.
Frequently Asked Questions
Can I use solvents in it?
Yes. That is what it is built for — Viton throughout.
Can I use harsh acids in it?
It has brass in the fluid path. For sustained acid work the all-plastic AS14A is the better choice, and dedicating a sprayer to acid is better again.
Is it rebuildable?
Yes, pump assembly and valve.
Why is it more than the budget sprayer?
Materials. Viton seals, a brass gun and a metal pump rod, against a plastic valve and extension. You are paying for chemical compatibility and serviceability.

What We See in the Field
Sprayers are rarely worn out. They are chemically killed — usually by one sprayer being used for everything, or by product left in the tank over a weekend. A second sprayer costs less than two rebuilds and a lost morning.
