This cone allows easy measuring of rubber O-rings inner diameter.

Just place the O-ring onto the cone and read the diameter on the cone.

For example, O-ring on the sample photo has 27mm inner diameter.

Measurable range is from 5mm to 40mm with 1mm increment. This will not allow precise measuring of O-ring with Imperial or fractional metric size, but +/-0.5mm tolerance is sufficient for most practical purposes.

The cone is 3D-printed with advanced technology with high resolution that provides nice appearance.

Hollow interior to reduce weight (31g only). The flat base allows mounting it to a table if necessary, though handheld usage seems to be more convenient to me.

Total height is 159mm. Step height is 4.2mm that allows measuring O-ring with up to 8mm section diameter.

Within the EU, the goods usually arrive within a few working days. Deliveries outside of the EU can take from just over a week to two weeks. Even an exchange or return within 14 days can be handled more quickly, cheaper and less complicated on the MJKZZ.DE page, if the items only need to be sent back to Germany/Austria. For large orders OUTSIDE of EU contries, it is possible that the shipping costs need to be calculated manually becasue of insurance. But we only charge the real shipping costs!

If you are ordering OUTSIDE of EU: Please contact us to place your order without VAT. We will send you an invoice excluding 20% tax.
