We provide a full range of turning static seals solutions, covering standard general-purpose and high-pressure special products. RCFL106/102 and RCK126 are basic models with simple structure and wide application; RCS130/131 and RCFL108 adopt extrusion outer diameter installation design to ensure the stability of groove embedding; RCK120/127 and other similar series products achieve the same reliability through extrusion inner diameter installation.
In response to flange sealing needs, RCF110 and RCR118 can bear pressure in both directions, and the pressure direction must be indicated when ordering. The product line fully covers low-pressure to high-pressure working conditions, and the material is wear-resistant and corrosion-resistant, and is widely used in hydraulic systems, pipeline connections and industrial equipment sealing.
