need some help adapting nitrogen regulator

admin

hi, pieced together a nitrogen charging set up for doing mx bike shocks and what not. i pretty much have the tank and regulator hooked up nicely,  and then i have my no-loss air chuck hooked up to my air line with the aid of a 1/8" female coupler.my issue is this, when i read the specs for my nitrogen regulator is said the outlet is a 1/4". so i ended up buying a 1/8" female to 1/4" female adapter, which does not fit. the 1/8" side fits my hose, buts its obvious the nitrogen regulator outlet is not a 1/4" size, or at least its measured in a different manner then the hose adapter i have. to me, it looks like both are 1/8" but one has fine threads (hose) and one has course threads (nitrogen regulator outlet). it also seems to me that the course threaded connection on the nitrogen regulator is very very slightly larger then my air line. here is a picturewhere can i find this adapter online? or is it even available? i bought the hose from powertank.com, are they using a proprietary end on the hose they supplied me? thanks guys, complete newb but i figured a welding forum would be the place to ask this type of question.Last edited by roobix; 05-19-2012 at 05:19 PM.
Reply:Can you remove the brass fitting from the regulator? Its looks from you pic that it is 1/4 pipe screwed into the regulator. If that is the case then you will need a bushing from 1/8 pipe to 1/4 pipe.

Reply:That air line should screw right into the reg, shouldn't meet any of the brass stuff.  It looks like you may have a straight thread on the 1/4" side of that adapter for hydraulic work.  The 1/8" side is a 45deg flare fitting and may not be The correct thread for your line.  The 1/8 threads on the flare side are straight also.  All of your threads should be NPT (tapered). Pay attention to the MAWP of all of your componentsExperience is something you get right after you need it
Reply:How much pressure do you usually use ? How do you read or set pressure ? Do you just use regulator or a specific gauge for reading ?   Reason I'm asking is that you could leave fitting on regulator and get a refrigerant gauge manifold.  http://www.bing.com/shopping/search?...FORM=HURE#x0y0The manifold will have one common hose connected to the nitrogen regulator and then either the low pressure side hose or the high pressure side hose depending on pressure required connected to shock.  I don't know how critical the pressure is but this would put it right on. Just thought I would mention this.   If you do remove fitting , use a six point wrench.

Reply:Your hose 1/8" male pipe thread. Regulator outlet is 1/4'' female pipe thread.Glad you posted linkYou need a 1/4" buy 1/8'' threaded bushing. The 1/4'' is a male that goes into reg and the 1/8'' is female for the hose.THIS IS IT,    Ihttp://www.fastenal.com/web/products/detail.ex?sku=69850&ucst=tT,
Reply:Your usual regulator thread is 1/4" NPT, and the pigtail appears to be 1/8" NPT, not flare. Removing the outlet fitting is easy.You need a common reducer bushing. They are under ten bucks online.Take your parts to your local HYDRAULIC supply and play match up. They have plenty of fittings to connect whatever you happen to have.You can thread the parts together on the spot, hand over a few dollars, and go about your business. The hydraulic shop may even have a coupling to go between the fitting on your regulator and hose without removing the original outlet fitting. Fitting matchup is a lot of any hydraulic shops business.Last edited by farmall; 05-19-2012 at 10:06 PM.

Reply:I have a hunch that the hex of a 1/4x1/8 hex bushing won't clear the regulator's body.Probably have to start with a nipple or else adapt to the flare with a flare swivel x NPT.Good Luck

Reply:Those last pix cleared it up, you do need a bushing, but as also mentioned, a standard hex bushing will probably not fit.  Nipple and a bell would do it, but at the pressures you want, don't use home depot crap get real pressure rated fittings and pipe.  A bell will have  both ends female, a nipple is just a short pipeExperience is something you get right after you need it
Reply:Is that regulator rated for ~220psi output? I routinely charge/rebuild shocks.. and decided to bite the bullet and buy the powertank stuff.Miller: 200dx, Bobcat 225, Passport, Powermax 45, Milwaukee: Dry Saw, MagDrill, grinders
