PowAir Airsoft HPA Line Adapter / Hose Adapter from 4mm to 6mm HPA hose.

This adapter makes it possible to combine a 4mm HPA hose with a 6mm HPA hose. One side of the adapter holds the 6mm hose, the other the smaller 4mm hose.

This type of adapter is always required when the airsoft gun has a different HPA hose diameter than the regulator.

The PowAir Airsoft HPA Line Adapter / Hose Adapter is self-sealing and does not require any additional gaskets or Teflon tape for installation. Simple plug and play installation.

ATTENTION - Please note the connection diameter of the hose on the weapon! Depending on the manufacturer, Airsoft HPA weapons have either a 4mm HPA hose or a 6mm HPA hose.
