These plugs not only fit the 20lb tanks, but any cylinder from 4 to 40 LB with the OPD/QCC1 valve installed. These plugs are to keep everything, including water, out of your valve when installed. The silicone O-ring seals your valve so nothing, even water, can get in. No more dust, dirt, insects, mud daubers, water, or grease. Your inside rubber seals on your OPD/QCC1 need to stay clean so you get the best seal when hooking up your appliance like your grill, buddy heater, camp stove, LP Generator, or whatever else you use.These plugs allow for that and unlike the dust caps that you place over the the valve end, these stay put and will not come out when snugged down. A huge note to make is these will not hold pressure.
