2"Flash Cuff™ Vacuum Hose Connectors Male and Female Rugged construction and a unique design ensure that twisted hoses and cuff replacements are a thing of the past. Additionally, the Flash Cuff™ both swivels and locks – no need to choose one feature over another. Inside diameter of the cuff is the same as that of the hose, keeping turbulence to a minimum and increasing air flow. Cuffs allow your hoses to swivel – don’t spend your time untwisting tangled hoses. Easy push-button lock keeps your hoses together whether you’re going upstairs or around corners. Tapered ends and shorter length allow the Flash Cuff to fit on the hose reel and keep its shape better than competitive products. Also available in 2.5" cuffs.
