O-rings are the most versatile and economical form of sealing device available.
O-rings will conform most readily to general design guideline recommendations, as they have the most extensive record of service life in diverse conditions.
O-rings are mainly used in static applications, sealing against liquids, gas and general environments.
At Superior, we pride ourselves on our precision o-ring range which exceeds the cross-sectional tolerances for the following dimensional standards;
- ISO 3601-1
- DIN 3771 Part 1
- BS 4518
The benefit of close tolerances on an o-ring cross section (d2), is the ability to reduce our customer’s tolerance chain and improve the overall performance of the customer’s product. In the Superior o-ring size list, the internal diameters conform to ISO 3601-1 tolerances and the cross section diameter has a reduced tolerance. These precision o-ring tolerances apply to NBR 70 compounds. O-rings manufactured in other compounds and hardness’ are produced to conform ISO 3601-1 tolerances, however dimensions for the internal diameter may be towards the lower end.
Our state of the art tool room designs and manufactures precision prototype and production moulds to meet the engineering challenges of our customers. To find out how this can benefit you and your customer go ahead and contact us on email@example.com or call +44 (0)1202 854300.
