Igual como en la imagen y funciona muy bien

Me gustó mucho, sella bien cero fugas, sin necesidad de sujetarlo cuando engrasa, bastante largo para alcanzar todas mis aplicaciones.

Great product.

Works great I don’t mind greasing my tractors anymore. Saves Time because I don’t have to clean up the mess around the Zirk fittings

Pricey but GREAT!

Fits standard grease nipple on John Deere Tractor 1 series. Takes the hassle out of greasing hard to reach locations. Lock on with one hand, and pump grease without any struggle in maintaining enough pressure on the nipple. Grease does not ooze out and works well on dried /caked on locations. Great buy! Get one for your Dad!
