This tool changes the way landing gear struts are serviced. No longer do you have to put an aircraft up on jacks to add fluid to and fill Oleo type landing gear. This is a totally clean and safe process. No oil is spilled. The strut valve is not disturbed and the plane is sitting on the ground the whole time. This is safe for the technician and the aircraft.

  • Built in pump forces fluid into the strut to top it off and the excess is drained off controlled right from the unit
  • Large capacity 5 qt storage tanks are big enough for just about any strut
  • Can be used on struts requiring up to 3000 psi strut pressure
  • Made in the USA


  • Totally safe and totally clean! –No clean up. No oil on tire and brakes or the shop floor
  • 10X Faster -Save time and money because you don’t have to drag the jacks out and lift the airplane
  • 10X Safer- the airplane never leaves the ground, the technician doesn’t have to be under the aircraft while the strut is being ser¬viced nor does the mechanic have to compress and extend the strut
  • 3X the Flexibility -Strut service can be done now on the ramp or at remote locations freeing up hangar space and giving maintenance personnel more flexibility

This tool is fantastic. Makes servicing struts very easy, clean and quick. As an A&P mechanic and owner of two Piper aircraft, I highly recommend the Bogert Pressurized Strut Filler

The product works like a champ. Easy to use. Purchased some 5606H and Granville Strut Seal and followed the instructions for use (IFU) of the Bogert Strut Filler Tool. Great product!

I am an owner of 1995 Commander 114TC. Since it’s recent purchase, the strut has been service once years ago. I purchase Bogert pressurized strut filler tool to service all the landings. Assisting the A&P, the process was fast, safe, clean and reliable. The one of the main strut was less fluid than the other during extraction. Old fluid was dark red. Now all landing gears has equal amount of fluid by number pumps before N2 was added. The aircraft stance look better and I feel comfortable that the gears was service correctly based aircraft manual. I highly recommend this tool to all complex aircraft owners out there. It’s must tool. Thank Bogert aviation!

Nearly impossible to use on low-wing fixed gear aircraft. The tool works when assembled properly. When I attempted to use it the first time, nearly every single fitting leaked and needed to be corrected. In addition the Schrader valve adapter is nearly impossible to screw onto a strut valve on my Piper Cherokee. It took nearly 2 hours just to screw the chuck onto a single Piper Cherokee main-gear strut. The truth is the adapter is simply too bulky to easily screw on. In addition the chuck was faulty and I had to order a replacement as the inner threads slip when turning the nut of the chuck. After correcting the above issues the tools works as expected. I would expect for the price I paid for the tool to get much better quality. The tool is made from about $150 in parts and theyre charging nearly $1k for a poorly assembled, poorly quality checked tool that I ended up redesigning anyway. I had to design and 3D print a special wrench just to be able to screw the chuck onto the Piper main struts. In order to screw it onto the nose wheel strut I had to remove the throttle cable mounting bracket as the adapter is just too bulky.
