Review on IRWIN 1218ZR Tap 6 32Nc Bottom - Premium Quality for Precise Tapping by Jesus Baker

Glass or similar material. I bought this faucet in a 3 pack which also included a taper faucet and a cork faucet both worked with no problems but this 1. Not much, it broke almost immediately and after a lot of work I was able to remove it and clean it with it clicks again just as quickly. Needless to say I am very disappointed and don't want to try them again, especially these ones!
