RTV Oil Wiper Packing

Dual-Acting: Wiping and Sealing

RTV oil wiper packing effectively removes lubricating oil film from the compressor rod while creating a continuous gas seal between the crankcase and distance piece. This dual function virtually eliminates oil leakage as well as the harmful effects of fugitive emissions.

Superior Performance

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.

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.

Retrofit Capability

RTV packing is available in many of the most common groove sizes, making retrofit an easy process that usually requires no modification of the case.
