Landing gear strut packing seals shrink due to fluctuating weather conditions and age. This specially engineered hydraulic chemical additive leaves a protective coating on the strut shaft and allows the seal to expand to its normal size. It will stop strut leaks and is an excellent lubricant and corrosion preventative. Application is fast and easy - any owner or pilot can do the job in minutes. FAA approved. Manufacturer has no stated shelf life.
Used on front wheel strut on 1956 Cessna 272 that had lost all its hydraulic fluid. A couple of weeks later still no signs of leaking fluid. Time will tell.
GRANVILLE #5 KIT SNGL STRUT SEAL 4OZ
GRANVILLE STRUT ADDITIVE PINT
Seal worked perfectly and save me $2500.00 on a new nose wheel strut for my Cirrus SR22T.
Purchased Granville Strut Seal and some 5606H. Used this with the Bogert Strut Filler Tool. Outstanding results! Easy peasy. Clean and efficient!
This stuff is UNBELIEVABLE!!! I had a completely flat front strut that wouldnt hold air whatsoever. The existing fluid level was at about 75% full but the strut cylinder was wet from obvious fluid leaking. My mechanic told me about this stuff (expensive as it may be) and I decided to give it a shot. Everyone else said I need to rebuild the strut with new rings so I ordered a rebuild kit too. We inserted the Granville to see if it would work and it is absolutely a miracle cure. One week later and about 8 crosswind take off and landings its still holding strong. $50 bucks for 4oz but it saved me about $300 in strut rebuild labor.
We keep it in stock at our maintenance hangar. Every strut re-seal we use it. Have never had a comeback with a strut issue.
Im skeptical about snake oil products and ordered the strut rebuild kit at the same time to have on hand. Bottom line is I have a strut rebuild kit for sale if anyone is interested?!
Has always worked well...have used it for years.

The additive is in each kit. The additive is available in a pint size only, if the user already has the applicator in the kit.
No, this is not considered hazardous material.
You shouldn't need this on a freshly rebuilt strut, only if you are having slight leaking issues.
It gets mixed in with the 5606 when you service the strut, you would only need the tools required to perform the strut service.
