Holmbury High Flow Safety Couplings offer two important benefits, high flow and low pressure drop characteristics and safety locking mechanism to prevent accidental disconnection.
The F series couplings are designed with an oversized poppet which accounts for the high flow rates, it also has a built in pressure release mechanism within the poppet allowing for easier connection/disconnection. Available in sizes 3/8″ and 1″, in BSP thread.
