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.

A brand you can rely on with quick, and efficient simple air bleed system. Cheaper brands with black casings heat up and leak grease in warm storage conditions - something to be aware of. I found with cheaper brands you constantly needed to re - bleed the system. Don't waste your hard earned money and but the K29.The extra long flexible hose feed is handy for hard to reach areas and super tight spots.
This item arrived well packed and quickly after purchase. I have now used it to grease my Kuboda tractor and my Toyota truck. The tractor had some difficult grease nipples to reach which is why I went for the flex head on the grease gun. This is my second Macnaught grease gun the original I purchase almost 30 years ago and it has given reliable service for many years. I highly recommend the Macnaught grease guns and Revolution Industrial for there prompt and reliable service.
This model grease gun is used on many farms in this area and I have used them on places I have worked. So when I needed to buy a grease gun, this was naturally the one I got. Easy to use with no mess using the cartridge refills and has plenty of pressure to force grease in where it hasn't been for years.
Easy to use, solid construction, good product. Allows those tricky to access grease points to be reached.
Always been a high quality product
Great Grease gun,, a little on the expensive side however should last for years. Easy to use in those tight to get to place's in the vehicle and take's a grease cartridge, A good buy.
Very happy with this gun. No more stopping and having to clear the over and over air blockages I use to get on the old one
