Air is 79% Nitrogen (78%N + 1% Argon). "dry" Nitrogen(N2) and "dry" Air(low dew point) are often close enough to be used interchangeably. Expansion rates are also similar enough. "dry" Air- (low dew point/ super dry) is like you get at a SCUBA diving shop, it's air that has been cooled to ambient or lower temp before being filtered for water. Water/vapor is the biggest problem, with enough heat water can flash off into steam and spike pressures. Water + air can support corrosion. Important: Not all Nitrogen is "dry", welding tank type is usually cryo separated and pure(dry). Tire shops/commercial often produce N2 on-site using PSA separators. PSA's are basically a filter system for air that removes O2, problem is that many/most "tire" systems have crappy filters and they filter the air hot (so- HI dew point or wet N2). Another concern is "pressure loss", O2 is smaller than N2 so any pressure loss would be slightly higher with Air. Now Back to the Real World-- I mostly use "dry" air. I made an inline filter filled with desiccant to dry/filter any questionable air I use(cost-$5). Some use in-line driers like those for spray painting. SO.... pure N2 is best, but expensive and a pain to deal with. Quality "dry" Air is adequate for most, cheap, easy to deal with. Coin operated gas station air pumps are the worse! They pump a lot of water/vapor, which is why I always have my in-line filter with me "just in case". BTW in my filter I mostly use Activated Alumina beads- cheap, stable ceramic (won't dissolve), re-usable by baking the loose beads at 400 F to dry out. About me: Learned about Hi pressure gas systems in the Navy, later owned 2 dive shops and a compressor biz. semi-retired now and love to tinker with ridiculously over powered air-guns/cannons.

Have you had any failures when using the SELF-SEALING NITROGEN CHARGING BOLT from Racetech? It seems there are many complaints on various forums of the bolt failing to hold pressure. Without taking into consideration the effort to install a Schrader valve, would you recommend the Racetech bolt or Schrader Valve option. Thanks for making this video, very helpful

This is great, thanks. That said, the manual makes this look like an impossibly difficult task. Do you need to check the internal piston location every time? They have an insane machine for purging the shock... does that need to be used?

Great video man, can you do some videos of how to safely use the nitrogen to fill a shock with the needle set up? I'm planning on servicing my Fox MTB shock, Ive done rockshox shocks many times but they use air and a schrader valve but I'm new to Nitro.
@SpicyCarModz Жыл бұрын
Question for ya. I've got some shocks, and after removing the plug at the bottom of the resevoir, theres no shrader valve at all. It looks like it has some kind of round rubber stopper at the bottom of the hole, but no visible le Mark's on it Not sure what to do about filling it now.

Yea. If you hook up the tire inflator on the end of your nitrogen hose. I have a aircompressor fitting on the end of my nitrogen hose and then I can connect a tire inflator like he showed. But make sure your inflator is properly rated. 150psi off the top of my head.

Dohan Kuswardi No, do not let out any nitrogen. The shock needs to be fully charged or it will cavitate and make things worse. Use your clickers. Or have the shock sprung and valved for you.
