A Professional Grade Solid Brass Regulator with Clean, Uncluttered Gauges
Made from solid brass, this regulator is designed to handle the toughest conditions.
SPARC’s 2" gauges feature easy to read, single-scale (PSI) faces, and are surrounded by rubber protectors to prevent dents and dings. With a clear, clutter-free gauge face—no metric scales to confuse your view—you'll always get an accurate reading, even in demanding environments.
This tool is great for welding, brazing, leak checking air conditioning systems, filling tires + shock absorbers, and more!
Effortless Hook-Up for Any Job
Connecting your tools has never been easier. SPARC’s nitrogen regulator features a CGA-580 inlet (.965″–14 NGO threads) that will fit almost any inert gas tank, including Nitrogen, Argon, and Helium.
The 1/4" SAE Male Flare Outlet with 7/16”-20 threads ensures a quick and secure connection to your HVAC gauges and other equipment. Plus, a built-in safety pressure relief valve adds an extra layer of protection from over-pressurization.
Precision Control with the Large Brass Tee Handle
Experience smooth and accurate pressure control with SPARC’s Large Brass Tee handle. Designed for easy adjustments, it allows you to fine-tune the output pressure to your exact needs, and is extra large to ensure durability and long-lasting performance, even in demanding environments. A tiny dab of grease or oil on the threads as needed will keep adjustments smooth for years to come.

I bought this for making a setup to charge motorcycle shocks. I've used it several times and it is still working just fine.

Stuck on wrong pressure, everything else works as intended.

Perhaps not the finest control over the outlet pressure, but it worked perfectly fine for a mini split install pressure test. Did not leak once it was tight, and I really appreciated that it has the 1/4" fitting so common for mini split pressure hoses. Hooked right up to the rest of the parts I bought on one side, and to the small N2 tank on the other side.

Seems a little noisy at low flow, but it works well & does not leak.

I only used this regulator a couple times so I can’t say how it will hold up over time. I usually try to wait a little while and really use the product before I write a review. With this regulator I know I won’t be using it much. For the times I have used it I have no complaints. When I opened the box I was surprised this seems like a real good quality regulator. The gauges are almost perfectly accurate. The body was heavy brass. It sealed nicely no leaks. I didn’t test the max pressure but it easily went to 400.

Some reviewers noted that it wouldn't hook up to an AC Manifold Guage Set, which I found to be true and frustrating, but some review of the Manifold manual and research, I found the exact adapter that would solve the problem. The regulator output is 1/4" MFL (flare fitting) and the yellow hose (on my AC Manifold set) is 1/2" ACME . So to connect to the nitrogen tank, you need this adapter to convert the regulator output from 1/4" FL to the 1/2" ACME. Worked like a charm. Hope this helps.https://www.amazon.com/gp/product/B000LQN6HM/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1
