O-Ring Loaded Seal, L Shape
The L-shaped o-ring loaded seal is made up of an o-ring, measuring up to GB/T3452.1-2005 standards, and a PTFE filled seal that is of an L shape. This single-acting rod seal is suitable for use with the guide ring and piston ring, and fits around a reciprocating rod or piston in a high-pressure hydraulic system where pressure is applied from one side only. For a rod with a diameter less than 100mm, we suggest going with an open-groove seal design.
Operating conditions
Operating pressure: 0~60MPa
Operating temperature: -55~ 2500°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.
