Fits the Taprite and NADS brand regulators sold by William’s Brewing from late 1994 on. This inset washer does not need replacement unless damaged.
Note: This is currently an O ring and not an X ring as pictured.

Q: Does this fit the CMBecker regulator?
A: No, see our items Q72 or D19 for washers that fit the CMBecker regulator. Note that the CMBecker regulator comes with a reusable nylon washer for the C02 tank seal.
Did not receive the item in the picture.
I thought that I would have received the rubber CO2 tank washer pictured, but I received O-rings instead. Shipping price is not worth returning. William's Brewing Responds: Yes, they are O rings and not X rings. We will update the picture. They should work to hold the C02.
Leak Stopper
My regulator was purchased (used) with a damaged washer. The new washer is tough to get into the groove on the regulator, but it works great once installed and fixed my leak. Price was right so I purchased a spare.
