This hose fits perfectly on my Shop Vac L250 without tools or tape. /4" and put it in this new 10" hose. This new 10" hose came with a 1-1/4 to 2-1/4" adapter collar that must be removed first. The adapter sleeve was glued onto the new hose. The quality is similar to the original 1-1/4 Shop Vac hose.
