O-ring measuring cone
For O-ring diameters from Ø 5 mm – Ø 300 mm
No more inaccurate O-ring measuring! Now you can quickly and easily identify O-rings and seals in the range of Ø 5 – 300 mm.


O-ring measurement made easy!
Our O-ring measuring cone allows quick and easy measurement and identification of O-rings, seals, support rings or the gap dimension for guide rings. The O-ring measuring tower is produced directly by us in Mannheim, Germany. As a manufacturer, specialized in the production of seals and related products, we know what it takes to build the perfect O-ring tower.
Use it by simply push the seal onto the cone until the diameter is reached on which it fits snugly everywhere. The diameter is determined in 1 mm increments.

Why you should use the Oring sizing cone?
Elastic O-rings can often only be measured inaccurately with calipers, as they can easily stretch. This is not the case when measuring with our stable O-ring sizing cone. The O-ring lies exactly against the cone and you can easily read the diameter. The slot width of guide rings and back-up rings can also be easily measured with our measuring cone.
Variants
The measuring cone for O-rings is made of POM and is available – as a set or separate – in six diameter ranges:
| 005 – 064 mm | 065 – 104 mm |
| 105 – 154 mm | 155 – 200 mm |
| 201 – 250 mm | 251 – 300 mm |
Tolerances
| Up to 104 mm diameter: | +-0,03 mm |
| From 105 mm to 300 mm diameter: | +-0,05 mm |
Never measure incorrectly again with the O ring sizing cone!
