Wiper Rings

Wiper packing acts to maintain oil in the crankcase. Seal rings in the wiper packing also minimize the flow through the packing caused by the pumping action of the crosshead. Common wiper ring styles are presented below.

Contact your T.F. Hudgins representative for more information and engineering assistance with your application.

 

RTV Wiper Rings

The RTV wiper combines a highly effective wiper ring with a side-loaded seal ring. It occupies less space than traditional wiper packing sets. The wiping edge is axially loaded against the side face to effectively reject oil from the groove and the butt-tangent ring seals gas from the distance piece.

 

 

 

 

 

2RUG Wiper Rings

The 2RUG wiper ring set is a non-metallic oil wiper with axial and radial drains to maximize the flow of oil away from the rod.

 

 

 

 

 

 

3RWS Wiper Rings

The 3RWS wiper is the basic and most commonly used wiper ring combination. The only function of the 3RWS is to wipe the rod and drain the fluid away. The '3' indicates that the RWS ring configuration is doweled to prevent alignment of cuts.

 

 

 

 

 

560 Wiper Rings

The 560 wiper ring set is made up of two wiper rings and a butt tangent seal ring that combines the wiper/seal function into one groove. They are installed with drain notches of one wiper toward the oil source.

 

 

 

 

 

 

561 Wiper Rings

The 561 wiper ring set is identical to the 560 wiper ring set with two wiper rings and a butt tangent seal ring that combines the wiper/seal function into one groove. The difference is that the 561 wiper rings are installed with the flat face of one wiper toward the oil source.

 

 

 

 

 

RWS-BT Wiper Rings

THe RWS-BT is a wiper/seal combination ring installed with drain notches facing the oil source. This is utilized where space is limited.
