Review: Worked nicely for my A/C work - RX WELD Nitrogen Regulator with 0-800 PSI. Impressed by quality of machining on this unit. Had inlet filter on inlet to tank which was nice to see. High Pressure gauge have increments of 125 psi which is suitable for gauging supply tank pressures. Low - Supply Pressure gauge have increments of 20 psi, with zero pin and 20 psi being almost the same. This regulator might not be suitable for someone needing a quite low pressure output for very low flow work. It worked fine for supplying my nitrogen flow meter at 60 psi, as well as supplying 400 psi for a pressure test I performed. The gauge to tank inlet stem could be a bit longer so the gauges would clear the tank knob on a 125 cu ft Nitrogen tank when attempting to install the regulator with gauges in a straight up viewing, but it worked perfectly fine when rotated a bit to clear the tank knob. It just made viewing the gauges a bit unhandy. Hose supplied had a white plastic type gasket and worked fine for my work. I found after using this regulator with a 125 cu ft Nitrogen tank that the inlet stem of the regulator should be at least 1 + inch longer to allow clearance between the tank knob and gauge set. This would allow the gauges to mount vertically and Nitrogen Flow Meter if attached to hang vertically as it is intended to be used. I have not tried on a smaller 80 cu ft Nitrogen tank, but hope the smaller tank size will allow for adequate clearance so the Regulator will mount vertically.

Tank gauge was always stuck at 200 psig, never went higher. I checked with 2 other Nitrogen regulators that i borrowed from my friends and those showed 2000psig. Btw another buddy told me that he bought exactly the same regulator from this seller and had the same issue. So it must be a MANUFACTURING DEFECT that they don't want to fix or cover. I realized it past 30 days of return policy and now i'm stuck with this GARBAGE. Stay away from that seller and product, they don't have a phone number where you could call, and if you chat , they just redirect you to Amazon. No support, no customer service , they are not liable for anything , imagin if it leaks. ## Frequently Bought Together - RX WELD Nitrogen Regulator with 0-800 PSI, CGA580 Inlet, Delivery Pressure Equipment Brass Inlet Outlet Connection Gauges with Refrigeration Hose - Tools That Can Be Used for HVAC Tools Nitrogen Purging, Nitrogen Purging Tools, Nitrogen Regulators - Appion MGAVCT 1/4" MegaFlow Vacuum-Rated Valve Core Removal Tool --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/497372544-nitrogen-regulator-with-0-800-psi-delivery-pressure-equipment-brass](https://www.desertcart.tn/products/497372544-nitrogen-regulator-with-0-800-psi-delivery-pressure-equipment-brass) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-22*
