Atkinson - Model COM2180 -Black Top Cap Tankmaster Spare

Suitable for use with all sizes of Tankmaster Sight Tubes and all sizes of Push Button Sight Gauges. Tip received and passed on from a customer: Fit a small ball of ‘Scotch-Bright’ into the top of the sight tubing, before fitting the Black Top Cap, to prevent ear-wigs and other insects climbing inside and falling down into the oil, whilst still allowing the sight tube to ‘breath’.
