Description: External end of the Beswick QM3 series ultra miniature M3 quick disconnect. Internal end will shut off when disconnected. The QM3 series is a great fit for applications with limited space or weight requirements.

Max Pressure Rating: 250 psig while connected. Take caution when disconnecting lines under pressure since the external pin has no shut-off and will vent to atmosphere when disconnected.  Due to this, our recommended maximum pressure for connecting or disconnecting the assembly is 120 psig.*

*Note that the pressure rating of configurations using barbs will likely be limited by tubing selection.

Material: 303 Stainless Steel.
