Protekt Oxygen Regulator, CGA 870 or 540
Protekt Oxygen Regulator — Click-Style, Contents Gauge, CGA 870 or 540
Overview
The Protekt Oxygen Regulator controls and adjusts the flow of oxygen from a cylinder with a simple, dependable click-style selector knob. Each setting clicks positively into place — with laser-etched flow orifices for accurate delivery — so the flow won't drift, and a protective contents gauge lets you see how much oxygen is left in the tank at a glance. A built-in pressure relief valve and a 30-micron sintered bronze inlet filter add safety and durability, and every regulator meets or exceeds ASTM, ANSI, and CGA accuracy standards.
Built from solid brass and rated for inlet pressures up to 3,000 PSI, it's available in the configuration that matches your setup: choose your flow range (0–15 LPM, 0–8 LPM, or pediatric 0–4 LPM), your cylinder connection (CGA 870 for small post / pin-index tanks or CGA 540 for large threaded tanks), and your outlet (a barb for oxygen tubing or DISS for 50 PSI equipment). Full and mini sizes are offered on the 0–15 LPM model.
Configuration Options
- 0–15 LPM, Full Size, CGA 870, Barb Outlet.
- 0–15 LPM, Mini Size, CGA 870, Barb Outlet.
- 0–15 LPM, Full Size, CGA 540, DISS Outlet.
- 0–8 LPM, Full Size, CGA 870, Barb Outlet.
- Pediatric 0–4 LPM, Full Size, CGA 870, Barb Outlet.
- Pediatric 0–4 LPM, Full Size, CGA 540, DISS Outlet.
How to Choose
- Cylinder connection — CGA 870 is the pin-index "post" fitting on small portable tanks (M6, C, D, E); CGA 540 is the threaded connection on large tanks (M60, H). Match it to your cylinder.
- Outlet — a barb connects directly to oxygen tubing or a cannula; DISS is a 50 PSI threaded outlet for running equipment.
- Flow range — 0–15 LPM covers most uses, 0–8 LPM is a mid-range option, and the pediatric 0–4 LPM gives finer low-flow control.
- Size — the 0–15 LPM comes in full or mini; the mini is more compact on portable tanks.

Equipment Specialist Insight: Picking the right regulator comes down to three things — your tank's connection, the outlet you need, and the flow range. 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.

How do I know whether I need CGA 870 or CGA 540?
It depends on your cylinder. CGA 870 is the pin-index "post" fitting on small portable tanks (M6, C, D, E); CGA 540 is the threaded connection on large tanks (M60, H). Match the regulator to the tank you have.
What's the difference between a barb and a DISS outlet?
A barb connects directly to oxygen tubing or a cannula. DISS is a 50 PSI threaded outlet used to run equipment. Choose based on what you're connecting.
What's the pediatric 0–4 LPM version for?
It provides finer control at low flow rates for lower flow-rate needs.

This listing is for the regulator only; medical oxygen is a separate prescription item. Always follow oxygen-safety guidelines and manufacturer instructions.
