Part number for GW Kent CO2 stone check valve

[mckraut]

Does anyone know what the part number for that rubber cap "duck bill" piece that's inside the co2 stone? It's pictured here: http://www.gwkent.com/carbonation-stone-seal.html I'm tired of having to pay $15 a piece, since we seem to go through them like crazy.

Any ideas? Our stones seem to tear through them every couple weeks

Have you tried using Thomas valves?

Take a look in your draft supply catalog. The same part is the check valve for picnic pumps. Foxx Equip. # 12j06-103, $0.48.
