Needle Valve For CO2 Regulator

$24.99
SKU: DG1815
Web store price may not reflect retail store price.

Description:

This Needle Valve is most suitable for Aquarium use. It can provide down to 10 bubbles of CO2 / minute consistently (at 0 pressure). Fits most CO2 Regulator Kits on the market. Inlet - Male Threaded NPT 1/8" (measures 1/4" OD physically) / Outlet - Hose Barb 1/8" (or 4/6 mm ID/OD tubing).

NOTE: CO2 gas is extremely compressible, and therefore expandable, relative to other gases. CO2 gas is typically stored under very high pressure. A needle or metering valve is not designed to drop the pressure from your CO2 regulator down to a working pressure. This is the job of the CO2 regulator itself. The needle valve`s sole purpose is to regulate CO2 flow precisely. Equipping your existing CO2 regulator with a needle or metering valve may not provide you with adequate fine-adjustment for a calcium reactor. These valves are fragile and can be easily damaged if not hooked up to the proper regulator.
