Reelcraft 261683 Coiled Hose Reinforcement
Series 30,000 hose reels plumbed in 1" feature a coiled hose reinforcement. It can generally be found inside the spool upon opening the box. It is shipped loose and may be elsewhere in the box. Be sure to locate it before discarding the packaging. Further examination of the hose reinforcement should reveal that one end has an expanded diameter.
Once you have established which end has a slightly larger circumference, feed the other end, the narrow side inside your hose before installing the hose onto the reel.
With the hose reinforcement installed you may now install your hose on the reel.
The coiled hose reinforcement, when properly installed, ensures that the hose does not pinch or become restricted where the hose transitions onto the spool. It is necessary only on the 1" models. Smaller diameter hoses have less tendency to bend or pinch and are generally more supple, making a smoother transition.
