O-Ring Loaded Seal, C-Shape
With a groove profile shaped like the letter C, this o-ring loaded seal is comprised of an o-ring, which is built to GB/T3452.1-2005 standards, and a PTFE filled seal. A popular use of hydraulic seal is on the reciprocating rod of a hydraulic or pneumatic cylinder. For rod diameter less than 100mm, it’s best to use an open-groove seal.
Operating conditions
Operating pressure: 0~70MPa
Operating temperature: -55~ 250°C (depending on the kind of o-ring material)
Reciprocating speed: ≤6m/s
Operating media: air, water, ethylene glycol based water solution, mineral oil, acid, alkali, etc.
