Mountain air is thin so this was perfect! ### ⭐ Quality of materials is suspect ... ya get what ya pay for! *by J***R on May 18, 2025* I thought I'd at last found a regulator that would do 25 lpm for a price I could afford ... and it did work for awhile ... but it only lasted 6 weeks. Two weeks after the return date some inner seal failed completely, allowing a strong flow of oxygen to flow out at all settings, even 0. So ... cheap junk, imo, save your time and money and look elsewhere. Also the meter showing the level of oxygen was a couple of ticks off, I ran out of O2 when the gauge still showed half way up in the red zone. Cluster heads can avoid this one! ## Frequently Bought Together - 15LPM Oxygen Regulator CGA-540, Adjustable Flow 0-15 LPM - ASTM G175-03 - Aluminum/Brass, Max Inlet: 3000 PSI, Outlet: 50 PSI - Compact 1.38 inches X 6.29 inches - AireMed Oxygen Regulator 0-8LPM, CGA-540 Gauge – Brass Sleeve - 12 Preset Flow Settings - Dependable Oxygen Regulator --- ## 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.vu/products/603790883-resone-cga-540-oxygen-cylinder-regulator-adjustable-0-15-lpm](https://www.desertcart.vu/products/603790883-resone-cga-540-oxygen-cylinder-regulator-adjustable-0-15-lpm) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-05*
