O-rings are circular sealing elements with circular cross-sections, and are mainly used in static applications. The sizes are specified by the inside diameter and the cross section diameter. Our O-rings are manufactured according to metric and imperial international standards such as AS 568B, DIN ISO 3601 and JIS. Custom sizes of almost any dimension are possible, such as miniature O-rings, special O-rings with large dimensions and continuously moulded and spliced cord. We utilize O-Ring compounds formulated to meet the most stringent industry standards, including FDA, USP, KTW, DVGW, BAM, WRAS (WRC), NSF, Underwriters Laboratories (UL), Aerospace (AMS) and many customer-specific requirements.
They seal over a wide range of pressure, temperature and tolerance.
Ease of service, no smearing or retightening.
No critical torque on tightening, therefore unlikely to cause structural damage.
O-ring normally require very little room and are light in weight.
In many cases an O-ring can be reused, an advantage over non-elastic flat seals and crush-type gaskets.
The duration of life in the correct application corresponds to the normal aging period of the O-ring material.
O-ring failure is normally gradual and easily identified.
Where differing amounts of compression effect the seal function (as with flat gaskets), an O-ring is not effected because metal to metal contact is generally allowed for.
They are cost-effective.
