COMPATIBILITY & APPLICATIONS
Faucet Connection Requirements
The QMP508 adapter is engineered for faucets with 15/16-27 threading, the most common thread size found on kitchen and bathroom faucets in North America. This adapter works with most countertop water filter systems that require a diverter valve connection, allowing you to switch between filtered and unfiltered water without permanent plumbing modifications. Before ordering, verify your faucet's thread size using a thread pitch gauge or by checking your faucet manufacturer's specifications. QMP USA manufactures this adapter to strict tolerances for reliable performance and long-term durability.
π§ Always apply plumber's tape to the threads before installation to ensure a watertight seal and prevent cross-threading during connection.
