O-Ring Cord is supplied as a continuous extruded cord. O-ring cord can be used to fabricate custom o-rings where the standard sizes are not suitable. O-rings are probably most widely used and simplest types of seal they are found everywhere from plumbing installations to the space shuttle, they are common in engines and gearboxes, garden hoses, pumps etc. They can be used as face to face seals (like a gasket) or as shaft seals and facilitate both rotary and linear movement. They have a wide operating temperature range from - 30 deg Celsius up to + 120 deg Celsius and a high degree of chemical resistance
Strong flexibility, flexible bending, no deformation, no fracture
Avoid damaging the O-ring during installation, as this will cause leakage. Observe the following:
1The end-joined O-ring must not be stretched over the joint and the rest of the O-ring must not be expanded to its elongation limit.
2 Edges must be burr-free, radii and angles applied smoothly.
3 Dust, dirt, metal chips and other particles must be removed.
4Tips of screws and installation housings for other sealing and guiding elements should be covered by an assembly sleeve.
5 A suitable grease to be applied to the assembly surfaces and O-rings.
6 Elastomer materials are made smoother if they are heated in oil or hot water to approx. 80 ℃. This makes it easier to stretch the O-ring for assembly.
7 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.
8 The cord or joined O-ring should not be rolled over assembly surfaces. Ensure it is not twisted as it slots into the groove.
