O Ring Gauge - Imperial
The Pro O-Ring Gauge is a practical tool for maintenance personnel needing to select, size and measure O-rings. It is primarily designed to determine standard BS1806 and AS-568 O-Ring sizes, functioning as a clear and accurate O-Ring size chart.

How to use an O-Ring Gauge
Smaller O-Rings can be identified by matching them to the silhouettes along the side of the gauge. For larger O-Rings, place the ring around the two spindle halves at the top and extend the telescoping slide until the ring is held taut. The British Standard (BS) size will appear in one of the small windows near the top of the gauge.

Note
Gauge features imperial scales only.
