Festo QSM-M7-6-I Push-In Connector

This is the exact connector used and recommended for my HPA adapters. If you want a clean, reliable setup without guessing thread sizes or hose fit, this is the fitting to go for.

Key Features:

• Original Festo QSM-M7-6-I connector
• M7 male thread – matches the threaded port used in my HPA adapters
• Push-in for 6 mm hose – perfect fit for the 6×4 mm HPA line I recommend
• Compact, lightweight, and leak-resistant
• Sold in packs of 1 – buy exactly the number you need

Why this connector?
I specifically chose this model because it pairs perfectly with my HPA adapter designs: the threading, sealing, and hose fit are all tested in my own builds. That means less tinkering, fewer leaks, and more time actually playing.

Use it for:

• Quizcen HPA mag adapters
• Clean, low-profile HPA routing in your builds
• Replacing worn or cheap fittings with something dependable

If you’re unsure what connector to use for my HPA setups, this is the one.
