This handy device helps a person to identify and measure the size of a smaller O-Ring through matching them to the silhouettes along the side of the gauge. To find out the size of a larger O-Ring, place the O-Ring around the two halves of the suitable spindles at the top of the O-Ring Gauge. The slide is extendable, slide this until taut - the useful gadget will then reveal the British Standard (BS) O-Ring size in one of the small windows near the top of the gauge.

Gauge has imperial scales.
