Applications
O-rings are used predominantly for sealing non-moving machine and system components (static application) and media in liquid and gas form, e.g. flange and cover seals, threaded tube connections and the cylinder head and cylinder bottom for hydraulic cylinders. Under certain conditions it is also possible to use O-rings with reciprocating, rotating and helical movements (dynamic application). If the installation housing is finished properly, the construction design is right and the proper materials are selected, it is possible for pressures of up to 1000 bar to be sealed, with the use of back-up rings, where required. O-rings are used in many sectors, such as the fields of hydraulics, pneumatics, vacuum applications, the fittings industry, the automotive industry and in plant and mechanical engineering.
Installation
Avoid damaging the O-ring during installation, as this will cause leakage. Observe the following:
-  The O-ring must not be expanded to its elongation limit.
-  Edges must be burr-free, radii and angles applied smoothly.
-  Dust, dirt, metal chips and other particles must be removed.
-  Tips of screws and installation housings for other sealing and guiding elements should be covered by an assembly sleeve.
-  A suitable grease to be applied to the assembly surfaces and O-rings.
-  Elastomer materials are made smoother if they are heated in oil or hot water to approx. 80 °C. This makes it easier to stretch the O-ring for assembly.
-  Any assembly tools used, such as expansion mandrels or sleeves, should be made of a soft material (e.g. POM) and not have any sharp edges.
-  The O-ring should not be rolled over assembly surfaces. Ensure the O-ring is not twisted as it slots into the groove.
