Scope:

The Scraper Installation Gland Design Standard MS 33675 accepts the MS 28776 Piston Rod Scraper. The scraper is usually a split bronze ring designed to clean the surface of a piston rod. The scraper does not actually exclude contamination from migrating into the rod gland bushing or seal cavity. Although non-metallic exclusion devices that offer design improvements to the MS 28776 scraper are available, the design options are limited by the small space provided by the MS 33675 gland configuration.
