So i picked up the tank yesterday. had to swap away my brand new tank, but what you gonna do. so i got the co2 regulator from beveragefactory.com (see link 1). i also got a needle valve (link 2). so the main problem is a leak... and i'm not sure how to fix it. There is a leak between the regulator and the tank. I screwed it on as tight as I could by hand and it would not stop the leak. There is a washer in the regulator already and im not sure whether to put another one in there or if tighting it with a wrench would do the trick (I didn’t have a wrench). The PSI from the high pressure side was less than 500 (im assuming this was because of the leak). Also are the needle valve and reactor supposed to be connected via a tube? Cause this also seems to have a leak. Whatever anyone can contribute would be great! Thank you!!!

Regulators using a washer-shaped nylon, brass, or fiber seal between the regulator fitting and the CO2 bottle valve have to be tightened with a big wrench. They seal by tightening the nut on the fitting very tight, to compress that hard washerr, far more than what can be done without a wrench. I used a 12 inch long adjustable wrench to tighten mine, putting as much torque on the nut as I could.

Break out the crescent wrench and torque it down. It's definitely not a hand-tight job.
+1.

Tightening by hand is your problem; it will not provide a tight enough seal.
