EPeS QD Plug HPA Foster (external thread 1/8 NTP) – Lockable

Self-locking one-way QD Plug from EPeS introduces a new standard to the world of HPA. This coupling automatically closes after disconnecting the air supply, ensuring that the remaining air does not escape from the system or magazine and can still fire several shots even without the air supply.It is fully compatible with HPA gen2 Plugs, making it an exceptionally versatile and powerful component of HPA setups.

Choosing the right size and type of HPA coupling can be challenging, so before purchasing the coupling, verify the following information about your HPA setup to select the right coupling type based on its usage:

diameter of your supply hose (4mm, 6mm)
thread (M5, M6, 1/8 NTP)
thread type (external, internal)
hose end type (QD FOSTER, QD EU, push-in, etc.)

EPeS makes your life easier again by providing endpieces of all possible types precisely for your supply hose/regulator.For easier installation, it recommends heating the hose before fitting (applies to crimping); the working pressure of the couplings corresponds to standard HPA system pressures up to 300psi (20bar).
