Request a Quote
This o-ring energized slip dust seal consists of a split seal, which can be snapped open or shut, and a rubber o-ring that energizes this seal. The split seal is made of high-grade PTFE, making it suitable for handling severe sandy or muddy applications. This o-ring energized rod scraper is used when the primary objective is to prevent the ingress of mud and other contaminations, thereby increasing effective system service life.
Model Selection
Fits around a rotary or reciprocating piton rod, reducing the possibility of cylinder contamination from external sources, such mud, sand and slurry.
