Commercial Tyre Pressure Indicator Valve Cap 120 PSI
Tyre Pressure Indicator valve cap help with maintaining the correct tyre pressure which is
vital for fuel efficiency and tyre life.
The valve cap is colour coded for a visual check of the tyre pressure condition.
This valve cap is set to 120 psi for tyres that should have an inflation pressure of 120 psi , so when the tyre is inflated to 120 psi the yellow indicator part of the valve is covered over with a black sleeve.
As the pressure in the tyre drops the sleeve drops down to expose more of the yellow indicator , all of the indicator is exposed when the tyre loses around 20% of the pressure ( down to around 95 psi )
Easy to fit , make sure the tyre is inflated to 120 psi when cold , replace the existing valve cap with the indicator cap. Finger tigten the caps ( do not use any tools )
and make sure to see the black sleeve being lifted up to cover the yellow indicator.
Please note this product can not check if your tyre is over inflated and should only be used as a referance of tyre pressure conditions.
