This is an all-alloy construction, improved, adjustable high-dosage application pump which easily fits on to the threaded opening of our on and off road OKO Puncture Free tyre sealant drums.

The single-handed pump is designed to dispense up to 250ml per stroke (or smaller doses in 50ml marked steps) which equates to 4 strokes per litre for larger installations.

Whereupon return to us and we can supply you with a replacement. Instructions for use: Screw the OKO application pump to the top of the drum (the pump replaces the cap). Remove the valve core and clip on the nozzle end of the drum hose with the tap closed. Charge the hose fully with OKO.

Open the tap when you are ready to start injecting the sealant.

With the high pressure OKO pump the OKO sealant may be inserted against tyre pressure of up to approx. 80 psi: and each full stroke of the pump will apply 250ml (for smaller amounts unscrew and adjust the collar along the shaft, then tighten at the desired place) .

For the very high pressure tyres, reduce the pressure gently until the pumping action becomes easy. It is recommended that eye protection is worn whilst working with compressed air. Having applied the correct dose of OKO, close the nozzle tap, unclip the nozzle and replace the valve core immediately.
