Just an FYI if you have this older model NADS 70012 regulator that needs repaired and you want to take a chance on fixing it. NADS was bought by Taprite and there is no longer parts for any NADS models. However, the Micromatic Economy Series Secondary Regulator Repair Kit 8000-15 Is almost an exact match. The Economy Series Regulator Seat Capsule Assy 8402 is a little off, but I got it to fit. I had to tighten it down firmly. Also, don't forget a 84010 Seat Spring. It's also slightly smaller, but worked. http://www.micromatic.com/draft-keg-beer/regulators-pid-8011.html
I actually have two of these NADS Regulators and this Micromatic kit worked on one and not the other. Your odds are 50/50.
The older model Taprite repair kit looks like it could work also, but I didn't try it. The Diaphragm and Regulator Pressure Plate are one piece, but appear like they "might" work. http://www.chicompany.net/index.php...rch_in_description=1&keyword=regulator+repair
Also, the Draught Technologies repair kit looks like it might be an exact match, but again I haven't tried it. http://rapidswholesale.com/beer-sup...aught-technologies-regulator-repair-pack.html
These are very old regulators and you might just want to buy a new one.
