Slip Fit Type: This is a slip on tub spout, not screw-on type, so it requires a threadless 1/2" ID copper tube (5/8" OD) Also, make sure your outlet pipe extended 1-1/2" MIN to 2-7/8" MAX from the wall. Metal Construction & Chrome Finish: This bath tub spout is well made of stainless steel housing and a few plastic parts. Mechanism works perfectly and the chrome finish was flawless. Solve Leaking & Noise Trouble: This diverter spout would reduce the leakage and noise, no more whistles when showering. Easy Installation: Remove the old spout, slip this one on and tightened it up. The housing slips on the tube and sealed with an O-ring against leakage, so just keep the copper tube clean and smooth. Package Included: Tub faucet, 5/32'' Hex Wrench, Sandpaper in case in need. (Please refer the installation instructions in the listing if in needed.) This is a metal housing tub spout with diverter. It is the slip-on type, not screw-on, which is compatible with American Standard 8888026.002
