The filling is quite easy, it can be done in 2 ways:
- With an adjustable, all-alloy OKO Pump which fits the drum and applies pre-measured OKO at up to 8.5fl oz per downward stroke, against up to 60 psi tire pressure. No assembly or lubrication is needed.
- With pre-measured pails or full drums that are poured into the open tire well when fitting a new tire.
