Hi, I am wondering whether this stem is for faucet or urinal? http://www.keyhole.com.tw/wp-content/uploads/2011/11/AM_1116C_Word.jpg I found similar one and it seems to be part of urinal stop. http://www.lockeplumbing.com/detail.asp?c=Urinals%20And%20Urinal%20Parts&s=Urinal%20Valve%20Parts&s2=&sku=AME-9101-0240&r1=&r2=&r3= I know T&S commercial faucet also has a similar stem part: https://www.etundra.com/images/products/372x372/commercial-plumbing-supplies/faucet-parts/stem-assemblies/t-and-s-brass-002714-40-eterna-hot-cartridge-assy/15822-1.jpg I think my first link is more like a faucet stem, not for urinal stop. Does anyone knows? Thanks!
