Earl's Auto-Fit design provides the reliability and appearance of Swivel-Seal but are easier to assemble and less expensive. With the conventional single nipple hose end design used by some of our competitors, the nipple actually threads into the hose and is retained by the socket. The thread forms a part of the seal and a possible spiral leak path. The Auto-Fit nipple is barbed rather than threaded. In assembly the nipple is pushed into rather than threaded into the hose. The hose is compressed between the nipple and the socket, sealing at the barbs. Hose retention is positive (the same as SWIVELSEAL) and there is no spiral path for possible leaks. Auto-Fit hose ends are available in aluminum and stainless steel. The lightweight aluminum hose ends are suitable for most applications. The stainless units offer maximum corrosion and temperature resistance increased physical strength and are recommended for marine, chemical or high heat use and for exotic fuels.
