It does function but is very cheaply made and looks like an adaptation of a inexpensive grease gun. I used it on my aircraft maybe 6 times in a 3 year period before it broke. Not sure if the quality of the new ones are better.

Sadly the attachment to the strut filling valve is leaking air and every push just goes nowhere. Like an ordinary bicycle pump I need someone to push on the planes tail to fill it. Useless as a single person trying to do it.

I am an A&P and have wanted one of these for some time now. This one from ATS is almost half the price of the only other one I know of. I tweaked mine by adding a high pressure gauge and also a check valve to allow the use of Nitrogen without wasting Nitrogen. (see Youtube video). This pump from ATS is a very high quality and works as it should. I am happy with my purchase.

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.

Ordered strut pump from Oz, 5 days later it arrived well packed no damage, pump worked very well, no problems at all blowing up my Dakota 236 main gear and nose struts running off a 125/PSI compressor unit as the air supply, No hesitatin recomending this unit for AC under 5700KGs, great unit build quality! Thanks AS GM. Victoria Australia.

After getting through a little operator error I found this strut pump worked exactly as advertised. I will now explain operator error! After attaching the strut pump gooseneck fitting to the Schrader valve DO NOT allow the strut pump tool to move as you connect the nitrogen air source to it possibly tugging ever so slightly on the gooseneck fitting. Even the slightest counter clockwise movement of the gooseneck fitting will cause the swivel aspect of the gooseneck fitting to loosen and it will leak which will not allow the strut to be inflated, (you will not perceive the leak) and you will pump madly away until all your nitrogen is gone. (grin) My suggestion is to always connect the strut pump from the left side of the Schrader valve as this will help from loosening the gooseneck fitting as you flop around under the aircraft.

I previously submitted a negative review. I found that the hose had somehow loosened where it attaches to the pistons body. After tightening, the pump now works very well. I can now recommend it.

Outstanding product, works exactly as stated. After strut reseal only four or five cycles on the pump and back to correct height

Worked great on my Cherokee struts. The only negative comment is the air volume per stroke is minimal, but it did the job.

I have not been able to get the proper strut height without putting the plane on jacks. It must take 100 strokes of the pump to make a difference. I don t recommend. I would give it a 2.

Work great for pumping up the strut on my Cessna 182RG.
