Britool England AF Imperial Flare Nut Spanner Wrench These original Britool Hallmark AF flare nut spanners, made in England, were crafted from high-quality alloy steel for superior durability. Designed specifically for use on brake or hydraulic pipes, the unique gap in the wrench head allows it to fit securely over the pipe, providing a firm grip on the nut and minimizing the risk of slippage.
