The OKO TYRE SEALANT INJECTOR dispenses a precise dose of tyre sealant, eliminating concerns over under-dosing or over-dosing. The injector is re-usable giving a lifetime of use. The 150ml injector syringe is ideal for owners of Motorbikes, Mopeds, Scooters, Quad Bikes, All-Terrain Vehicles, Cars, MPVs, SUVs, Vans, Caravans, Mobile Homes, Horse Boxes, Boat Trailers, Mobility Scooters, Wheelchairs, Wheelbarrows, Lawnmowers, Grass cutters and Golf buggies. The patented double-screw attachment works on all regular auto Schrader valve stems (bicycle owners please note: you must have removable-core type Presta valves to dispense OKO through the valve core, check before purchasing). It avoids leakages, allowing mess-free application of OKO sealant. You can suck up the required amount of OKO from the bottle (having unscrewed the cap) by pulling up the plunger of the syringe. A Schrader-sized valve core remover is provided: it screws onto the end of the screw attachment. Although of course it is designed for applying OKO, the Injector is a product that can be used with any lubricants and other liquids used in the workshop (subject to the user cleaning the unit thoroughly as recommended).
