If you've got an Interstate Pneumatics HSR50 or HSR80 hose reel, this rubber hose stopper is exactly what you need to keep your workflow smooth! This solid molded rubber bumper is designed to let you keep a specific length of hose permanently outside the reel - super handy when you're constantly using the same amount of hose and don't want to pull it out every single time. The two-piece design cushions the stop when the hose rewinds, preventing that annoying slamming sound and protecting both your hose and the reel mechanism. It's perfect for both air and water applications, whether you're in the garage, workshop, or out in the yard. Installation is straightforward - just follow the directions for your specific HSR series spring-driven hose reel. The quality rubber construction holds up well over time, even with frequent use, and it maintains its shape and cushioning properties. Seriously, if you're tired of your hose either fully retracting or pulling out too far, this simple stopper makes a world of difference in daily use. It's one of those small accessories that you don't realize you need until you have it, then you wonder how you ever managed without it!
