RB01 - Rod Buffer Seal, PTFE
RB01 Rod Buffer Seals are used in tandem with a primary rod seal. This seal will take the high pressure spikes, keeping the primary rod seal from damage. The RB01 buffer seal will also keep pressure from building between the buffer and the rod seal. The energizing o-ring and the PTFE cap can be made from various compounds specific to the application - contact ISC for recommendations.
