Available here as a replacement for a cracked or lost hose cuff, it is used to attach various cleaning tools to the working end of the hose. The swivel feature helps to prevent twisting and tangling. You can also use it to make multiple shorter hoses from a single long hose by pairing it with the vacuum-end fitting (#67485, sold separately).
