Euro Air Line Adaptor - High Flow Female Coupling 1/4" BSP - FMTHFF
Euro Air Line Adaptor with 1/4" BSP Female Thread
Euro adaptors and couplings feature a high flow design, this higher flow rate enhances efficiency and performance of air tools and spray guns. The popularity of this air coupling style has made them into a European standard. Extra air flow is particularly helpful when using paint spraying equipment.
BSP thread sizes can be confusing; BSP size is not the same size as the physical thread diameter. When measuring BSP male taper threads the measurement should be taken halfway along the length of the thread. BSP female threads are always parallel along the whole length of the thread – see size guide below.
BSP size Diameter of thread
¼” - 13.1mm Approx.
