Reddit mentions: The best tire valve stems

I'm guessing you need something like this.

I'm linking that one because it includes three different angles, you'll probably have a better idea of which one would fit the best. Changing stems would probably be a better solution.

• Spare engine belt
  
• Assorted tools (Sockets in 3/8, 1/2 drive (plus T30-T50 torx bits, wobble sockets, extensions), mallet, screwdrivers, pliers, etc.)
  
• Tire plug kit and jack/lug removal tool, valve cores, valve stems (plus removal tool), ether (starting fluid), stick lighter
  
• Air compressor (even a cheap one from Walmart will do)
  
• Jumper cables or jump pack
  
• Engine oil, tranny fluid, t-case fluid, diff fluid, coolant and distilled water, washer fluid, brake fluid, funnel
  
• RTV, JB Weld, brake clean, wd-40, super glue, duct tape, bailing wire, ratchet straps, zip ties
  
• Fuses, wire in multiple gauges, test light or voltmeter, wire strippers, electrical tape
  
• Flashlight plus extra batteries/headlamp, triangular road flares, hi-viz vest
  
• Radiator hoses
  
• Food, water, blanket, earplugs (it'll get noisy after a while), paper towels, baby wipes
  
• First aid kit
  
  • Band-aids
    
  • Medical tape
    
  • 3x3 / 4x4 gauze pads
    
  • Hand sanitizer
    
  • Antibiotic ointment
    
  • Gloves
    
  • Trauma shears / scissors
    
  • Tweezers
    
  • Asprin, imodium (diarrhea), meclizine (motion sickness)
    
    • Allergy: Levocetirizine (Xyzal), Cetirizine (Zyrtec Allergy), Loratadine (Alavert, Claritin)
      
    • Don't take Diphenhydramine (Benadryl) or Chlorpheniramine (generic allergy relief) as these cause drowsiness
      
      You can't predict every failure, but this will fix most major issues enough to get you to a shop or a safe place to work. Give the Jeep a once over, front to back, left to right. Drive it at highway speeds for 30 minutes and source out any shakes, squeaks, rattles, buzzes, etc.
      
      Hope this helps.

They make them. These fit on my Goldwing, but I am not sure if they would fit your application.

Looking further, here are some that say car compatible. Looks like searching for uxcell might be the answer and you might get some cool colors.

I got the bridgeport 83 degree ones. Love them, the regular straight valve stems were so hard to reach with the huge rotors in the way. No problem with these 83 degree ones.

Or this Im sure that wedge has enough mobility and the top part can be clamped.

more sizes/cheaper here.

ULPT: when you get iced, pull out you trusty valve stem puller and repay the favor. It does no permanent damage but does cause them a huge headache.

Not a necessity, but the tire valves were $8.75 on amazon for a 4 pack, no hot glue was used, and I got a box of 126 chalk sticks for $9.99 also on amazon.

What are your thoughts as to how he actuates the sealer?

I've thought about building a diy chamber vac, and would rather just put one of these inside the chamber with this traversing the wall to the outside world. Costs less money and this way you don't need to hook up a separate gauge.

I think this extender piece is what you need for the gorilla valve filler.

just be sure to get a high pressure valve core for use in a shock. typical tube valve cores are not rated to the pressures that a shock will likely experience. They may fail or more likely just leak at these pressures. https://www.amazon.com/Fox-Racing-Schrader-Assembly-802-00-012/dp/B0022ZIV1G. The fox branded one will be more expensive but more likely to fit well.
