The K29 FLEXIGUN is a classic grease gun that incorporates a unique variable stroke piston and valve arrangement for true one handed operation. The push in handle is easy to use and requires much less effort to operate. Increased pressure can be produced by short strokes (low volume) or high volume using a long stroke (low pressure). Heavy duty pistol grip construction with comfortable ergonomics to suit 450g grease cartridges, bulk filling or Macnaught J3 grease transfer pump loading. The K29 is fully repairable with a strong die cast head and heavy gauge steel barrel for extra long service life.
