The industry has long awaited a DI Water Lab Faucet that would provide the durability and strength of a metal faucet, without the contamination and corrosion that metal introduces into the process environment. That was the goal and the achievement of DURALINE. Marquest Scientific's Duraline Faucets offer the ultimate in durability for commercial applications, featuring a full array of heavy-duty faucets that are built to withstand constant use -- and the occasional misuse -- found in commercial applications. Duraline provides the ultimate combination of updated styling and heavy-duty construction. Duraline models can stand up to the extreme wear and tear found in most commercial applications, plus they are backed by a five year warranty against material or manufacturing defects. -- so our customers know they are getting the best product on the market, guaranteed. All Duraline faucets feature a heavy duty, injection molded stanchion, no longer an extruded tube and the most durable control valve available. These control valves prevent handle wobble while ensuring a positive closed position and feature all PTFE sealing. An encapsulated PTFE shut off seal provides an ideal construction geometry for keeping the PTFE in compression for constant on/off operation.
