In some applications the extra height of the adapter makes the installation very tight. The Direct Fit Hose Ends help shave valuable inches in tight applications. Fragola Performance Systems Series 3000 Hose Ends feature the "cutter" method of hose attachment. The socket draws the hose over the nipple and into the cutter. The seal is formed by the cutter imbedding itself into the end of the hose. Use these hose ends with our Series 3000 Stainless Race Hose only. "O" rings included, replacements available.
