Your cart is empty.The SÜA SMP400 is a Heavy-Duty Nitrogen regulator designed for purging, pressure build-up and leakage tests in air conditioning and refrigeration systems. It is also widely used for the charge and recharge of nitrogen in shock absorbers as well as other industrial and scientific applications where a controlled pressure of inert gas is needed. The Inner connector is a CGA-580 that fits all standard Nitrogen, Argon, and Helium American tanks. The outlet connector is a 1/4" Flare that fits HVAC Charging Hoses for Purging and Pressure Testing and high-pressure lines. This regulator comes equipped with two - 2" gauges with rubber protectors. Delivery Pressure: 20-600 psi - Maximum Inlet Pressure: 3,000 psi Low pressure Gauge Range: 0 - 800 psi High pressure Gauge Range: 0 - 4,000 psi Available Options: Regulator Only and Regulator with Refrigeration Hose, (60 inches Long, 800 PSI Max Pressure and 1/4" Female Flare Connections)

I purchased this regulator to charge the air suspension system in my 2016 Ram 1500 and I was not expecting much given the great price.This item is perfect for my needs. For the price you can't go wrong!

I did a DIY A/C replacement with Mr. Cool. I didn't get the pre-charged lines so I used this set. I used it to pressure test the system over a few days. It worked great. Not cheep for one use, but way better than paying the 5K for someone to install my system.

Works well, only issue was the part that goes into the nitrogen tank had a little niche/ damage on it. Like a deep scratch. Didn't want to seal the first few tries, then I just tightened it a little more than usual and no loss.

Works as great as the more expensive one.. at half the cost.

I need to perform two 500 PSI nitrogen pressure tests. This regulator is pretty tough to turn up that far but it is capable of at least 500 PSI. I didn't try to get to 600. Overall, it was perfect for my application. The output gauge did match my HVAC gauge set pretty well. It was a great value for me.

Seemed very accurate when paired with a precision manifold gauge A/C set.Only minor gripe is when testing at 400psi (mid scale on the regulator gauge) you really have to exert quite a bit of turning force on the "T" handle... I doubt it would actually crank up to 800 psi if ever needed.Solid brass quality!

Everything with the regulator works except the outlet pressure gauge. The needle is on the wrong side of the stop. I’m only using this set up to gas race shocks and have another regulator at the end of the fill line. Don’t see a way to contact the seller about the issue. Other than that the product works fine.
