CGA 870 is the pin-index \"post\" fitting you'll find on small portable aluminum cylinders (M6, C, D, E), while CGA 540 is the threaded connection on large cylinders (M60, H). For the outlet, a barb connects straight to oxygen tubing or a cannula, whereas DISS is a 50 PSI threaded outlet for running equipment. Match the flow range to the need — 0–15 LPM covers most situations, and the pediatric 0–4 gives finer control at low flows. The click-stop knob lands exactly on each setting so it won't creep, and the contents gauge shows when a tank is running low. Always confirm your cylinder's connection before ordering. One important note: the oxygen itself is a prescription item — this listing is for the regulator hardware.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul class=\"enhdme-spec-list\"\u003e\n    \u003cli\u003e\n\u003cspan class=\"enhdme-spec-label\"\u003eBrand\u003c\/span\u003e\u003cspan class=\"enhdme-spec-value\"\u003eProtekt (Proactive Medical)\u003c\/span\u003e\n\u003c\/li\u003e\n    \u003cli\u003e\n\u003cspan class=\"enhdme-spec-label\"\u003eType\u003c\/span\u003e\u003cspan class=\"enhdme-spec-value\"\u003eClick-style oxygen regulator\u003c\/span\u003e\n\u003c\/li\u003e\n    \u003cli\u003e\n\u003cspan class=\"enhdme-spec-label\"\u003eFlow Ranges\u003c\/span\u003e\u003cspan class=\"enhdme-spec-value\"\u003e0–15 \/ 0–8 \/ pediatric 0–4 LPM\u003c\/span\u003e\n\u003c\/li\u003e\n    \u003cli\u003e\n\u003cspan class=\"enhdme-spec-label\"\u003eSizes\u003c\/span\u003e\u003cspan class=\"enhdme-spec-value\"\u003eFull \/ Mini (0–15 LPM)\u003c\/span\u003e\n\u003c\/li\u003e\n    \u003cli\u003e\n\u003cspan class=\"enhdme-spec-label\"\u003eCylinder Connections\u003c\/span\u003e\u003cspan class=\"enhdme-spec-value\"\u003eCGA 870 (post) \/ CGA 540 (threaded)\u003c\/span\u003e\n\u003c\/li\u003e\n    \u003cli\u003e\n\u003cspan class=\"enhdme-spec-label\"\u003eOutlets\u003c\/span\u003e\u003cspan class=\"enhdme-spec-value\"\u003eBarb \/ DISS\u003c\/span\u003e\n\u003c\/li\u003e\n    \u003cli\u003e\n\u003cspan class=\"enhdme-spec-label\"\u003eGauge\u003c\/span\u003e\u003cspan class=\"enhdme-spec-value\"\u003eProtective contents gauge\u003c\/span\u003e\n\u003c\/li\u003e\n    \u003cli\u003e\n\u003cspan class=\"enhdme-spec-label\"\u003eSafety\u003c\/span\u003e\u003cspan class=\"enhdme-spec-value\"\u003eBuilt-in pressure relief valve\u003c\/span\u003e\n\u003c\/li\u003e\n    \u003cli\u003e\n\u003cspan class=\"enhdme-spec-label\"\u003eInlet Filter\u003c\/span\u003e\u003cspan class=\"enhdme-spec-value\"\u003e30-micron sintered bronze\u003c\/span\u003e\n\u003c\/li\u003e\n    \u003cli\u003e\n\u003cspan class=\"enhdme-spec-label\"\u003eMax Inlet Pressure\u003c\/span\u003e\u003cspan class=\"enhdme-spec-value\"\u003e3,000 PSI\u003c\/span\u003e\n\u003c\/li\u003e\n    \u003cli\u003e\n\u003cspan class=\"enhdme-spec-label\"\u003eBody\u003c\/span\u003e\u003cspan class=\"enhdme-spec-value\"\u003eSolid brass\u003c\/span\u003e\n\u003c\/li\u003e\n    \u003cli\u003e\n\u003cspan class=\"enhdme-spec-label\"\u003eStandards\u003c\/span\u003e\u003cspan class=\"enhdme-spec-value\"\u003eMeets\/exceeds ASTM, ANSI, CGA\u003c\/span\u003e\n\u003c\/li\u003e\n    \u003cli\u003e\n\u003cspan class=\"enhdme-spec-label\"\u003eSold As\u003c\/span\u003e\u003cspan class=\"enhdme-spec-value\"\u003eEach (select configuration)\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"enhdme-faq-section\"\u003e\n    \u003cdiv class=\"enhdme-faq-item\"\u003e\n        \u003cp\u003e\u003cstrong\u003eHow do I know whether I need CGA 870 or CGA 540?\u003c\/strong\u003e\u003c\/p\u003e\n        \u003cp\u003eIt depends on your cylinder.
