Grease Zerk "Protector"
Made from corrosion-resistant rubber, the "Zerkap" snaps over the head of the zerk and locks around the neck, creating a watertight seal. A flare at the bottom of the unit scrapes away any excess grease that remains after greasing and seals around the zerk fitting. The flare also prevents grease from getting on the cap.
Inventor Don Peterson, Midwest Companies, Inc., Merrillville, Ind., says, "If you just wipe the zerk off and then grease it, there may already be dirt inside the zerk so when you grease it you're just pushing the dirt down farther into the bearing."
Peterson originally developed the Zerkap for the trucking industry. "One problem with trucks on the highway is that liquid calcium chloride, which is often applied before a big snow, can get inside zerks and rust them out. We had such a good response from truckers that we decided to introduce the Zerkap to farmers," says Peterson. "The only limitation is that we can't guarantee that rocks won't knock the Zerkap off on an implement such as a disk that's down in the dirt all the time."
Peterson says he welcomes any feedback from customers.
The Zerkap comes in green, black, and yellow and will soon also be available in red. A "clamshell" of 25 sells for $10 plus S&H; a plastic tube of 20 sells for $8 plus S&H.
