RTV wiper packing provides a complete oil wiping/gas sealing solution in a compact, single-groove assembly.
A proprietary knife-edge geometry on the first ring of the three-ring assembly allows RTV packing to remove virtually all of the oil film wherever it contacts the rod. In addition, by remaining in a fixed position, RTV packing eliminates the “pumping action” that plagues other wipers and forces oil past the wiper packing.
In addition, the single-groove design creates a more reliable gas seal than any two- or three-groove oil wiper packing. The only way to achieve a more secure seal is with nitrogen or other buffered arrangements, which are available with custom RTV packing configurations.
All RTV ring materials are constructed of high-performance engineered thermoplastics, providing unmatched oil removal in a non-metallic, non-galling wiper that will never damage the rod.
