Once your tyres are filled with Nitrogen it's important that only Nitrogen is used for top up purposes. Adding normal air will negate any benefits of the Nitrogen. Nitrogen does not remove or reduce the need to check tyre pressures as the risk of a puncture or a slow leak is not altered.
The common practice at the moment is to indicate a tyre inflated with Nitrogen by placing a green cap on the valve. But as everybody knows, valve caps get lost very easily! That is why, to avoid that problem, we have created a green tag, the N2tag, that you fix onto the valve stem; it indicates that the tyre is actually filled with Nitrogen.
For simplicity we have marked the N2tag product in English, French and German, and with the international symbol for Nitrogen.
The N2 tag is also available for car/commercial based rubber valves.

Checkpoint® is manufactured from Polyethylene. This special grade is suitable for heavy-duty applications such as high load urban duty cycle service or where full axle loading is the norm.
Checkpoint® is designed to distort and melt at a vehicle hub/stud tempreture of 125 degrees centigrade. In addition for further severe operating conditions Checkpoint® have a high temp product with a distort/melt point of 135 degrees centigrade.
The material used is a virgin polymer and is UV stabilised. It is therefore dimensionally stable. The polymer does not degrade in sunlight. Checkpoint® can be cleaned using any of the available vehicle cleaning agents, detergent solutions or paraffins.
Checkpoint® are not attacked by road salts or petrochemicals. The pointer being large, it is highly visible even when coated with road or operational grime.
