O-rings are O-shaped cross-section which is made of elastomeric materials.
- Materials : NBR, HNBR, SILICONE, EPDM, FKM, FFKM, PTFE……and etc.
- Specialy O-ring specification request : Non-standard size、Hardness、Custon color.
AS568 . METRIC O-Rings
O-rings are O-shaped cross-section which is made of elastomeric materials.
- Standard size : AS, METRIC
- Materials : NBR, HNBR, SILICONE, EPDM, FKM, FFKM, PTFE……and etc.
- Specialy O-ring specification request : Non-standard size、Hardness、Custon color.
Back-up Ring
Back-up rings have no sealing function. High pressure and low hardness apply. It compensates the sealing gap and can use one site or each side of O-ring depending on the Pressure direction. It can support O-ring from migration and extrusion.

O-Ring Cord Board﹒Rubber Tube
PTFE Encapsulated O-Ring
PTFE encapsulated o-ring is silicone or FKM rubber o-ring coated FPA/PFA jacket. These kinds of o-rings have good chemical resistance, low friction and gas permeation.

- Standard size : AS568, P, Gs, JASO, V, Gm, Metric, Ss.
- Materials : NBR, HNBR, SILICONE, EPDM, FKM, FFKM, PTFE……and etc.
- Specialy O-ring specification request : Non-standard size、Hardness、Custon color.
- *O-ring Sizes:Inside diameter ranges
X-Ring
X-Ring is also known as Quad-Ring. The standard grooves are deeper in comparison with O-ring glands. The four lips emerge more sealing capacity. It will not spiral twist in the groove. The diametrical squeeze is lower than with O-rings to reduce friction to make the life longer. It is used in static and dynamic sealing.
