Part# 12-03731
MFR Model# 675A


Aircraft Strut Pump 10X delivers up to 1,500 PSI of pressure to raises struts without the need to place the airplane on jacks. Safety one-shot air delivery system gives you maximum control over the entire process -- each stroke of the delivery valve injects a small shot of high pressure air into the strut so that you can raise it in controlled increments. There is virtually no chance of you accidentally overpressurizing and possibly damaging your struts.


  • Newly engineered design now features 6061-T6 Aluminum cylinder for lightweight durability.
  • Operates on 50 to 150 psi air pressure (100 psi recommended).
  • Enhanced high pressure valve system rated at over 3,000 psi.
  • True 10X pressure magnification to produce over 1,500 psi from a 150 psi air source.
  • Also works with Nitrogen delivery systems.
  • Safety "one-shot" system delivers pressure to strut in controlled increments.
  • 24" High Pressure Delivery Hose.
  • MADE IN U.S.A.



This pump works as advertised. I serviced the nose and main struts on my 1965 Cherokee 140. It took 3 attempts but once I figured it out the job was a breeze. All the connections must be tight. No leaks allowed! I found that using pliers with padded jaws to tighten the goose neck on the schrader valve was necessary for a good seal Having someone to bump the wing and tail helps with sticking struts. Overall I am pleased with the pump and recommend it especially if you have no mechanic on your field (I dont).

Works well - good steady inflation of struts with a standard shop compressor.

Brilliant piece of equipment, try servicing a CAP10B or C on a private strip, without nitrogen, air, or a turner gauge, & youll appreciate the value of this little gem. Can be run off a small compressor, or compressed air tank, if no electricity source for your compressor. Many thanks

Does not work in process of getting it to fill strut hard to get manufacture to fix

Have not used it yet but it is well made. Just to note, the air fitting for your compressor hose is not included. Had to obtain at Canadian Tire.

10x Strut pump works well on my Apache, running on 110 psi compressor.

Outstanding product! Ive wanted one of these for a while and a recent move to an airport without many services necessitated that I become more self-sufficient. I ordered one but had some problems with the initially delivered item. Both Aircraft Spruce and Aircraft Tool Supply Company provided outstanding customer service in getting my issue resolved. My setup includes a nitrogen bottle, a reducing regulator (reduces from 2000 psi to 100-150 psi, and lower for tires). Some notes that may help you, however, you must follow all manufacturers recommended and required practices and I offer this not as advice, but to merely describe my experience: 1) Ensure the adapter is tightened securely as others have noted any leak source will allow the pressure to escape instead of be forced into the strut. I used some needle nose pliers to gently tighten slightly beyond finger tight to ensure a good seal. 2) I ensured that I used light machine oil to lubricate as described in the instructions prior to use. 3) My struts often stick I provided a few shots of airs and then tried some techniques to ensure the strut was not stuck: rocked the wings, jacked the aircraft slightly, or towed for a short period to get the strut to become unstuck and react. The lip to my hangar provides just enough bounce to get the strut to unstick and relax to its proper height, so thats all I needed to do this time. The tool allows you to inject finite amounts of air to get your strut exactly where you want it., but, if I overfill and I need to release any pressure, I just allow a short sprit out and re-perform the exercise to ensure the strut is not stuck again. I highly recommend this tool and am thankful for the outstanding customer service at both Aircraft Spruce and Aircraft Tool Supply Company. Final note: Aircraft Tool Supply Company has a lifetime warranty on the strut pump.
