I have for sale a Concoa 212 series 2-stage co2 regulator.

This unit consists of:

- A Concoa 212 series regulator - chrome plated (coveted by the planted tank crowd)
- A stainless Parker HR3 metering valve (super precise and more control than anyone would need)
- A stainless Burkert 300 series solenoid (120VAC - no voltage adapters needed)
- High quality brass pipe fittings with a Swagelok tube connection for the output

I snapped a couple photos for your viewing pleasure:

I am asking $235 shipped. Paypal only, please. No e-checks.

This unit has been thoroughly tested and works flawlessly. I am going to include a couple of the tube inserts you'll need for the Swagelok tube connection along with a spare set of front and rear ferrules. This connection requires the use of 1/4" OD X 1/8" ID tubing.

PM me about any questions you might have.
