- Place the included NSF gasket inside the QMP509A adapter to ensure a watertight seal.

COMPATIBILITY
Faucet Thread Compatibility
The QMP509A is designed specifically for faucets with 13/16-27 female threading, a common size found on many kitchen and bathroom fixtures. Before ordering, remove your faucet aerator and verify the thread size matches this specification. This adapter works with QMP countertop water filtration systems and most brands that use standard diverter valve connections. If your faucet has male threading or a different thread pitch, you will need an alternative adapter model.
🔧 Pro tip: Finger-tight is tight enough. Over-tightening brass adapters can strip threads or crack the fitting. If you experience leaking, replace the gasket rather than cranking down harder on the connection.
