The MITRE glycerine lubrication and inflation needles are an essential part of your kit. To minimise the risk of puncturing your ball bladder, or ruining the valve we recommend you use Glycerine on the pump inflation needle. Many balls are needlessly ruined by inserting dry needles or adaptors into the valve. Glycerine is easy to use, simply attach one of the 2 ball inflation needles to your pump and dip the tip of the needle into the Glycerine. Then insert the needle into the ball valve. When finished inflating, wipe any excess off the ball and needle. The pack contains one small bottle of Glycerine and two inflation needles. **NOTE** Unfortunately we are unable to post this item outside of the UK.
