-4 Straight Auto-Fit
Earl's Auto-Fit design provides the reliability and appearance of Swivel-Seal hose ends whilst also being more cost effective. With the conventional single nipple hose end design used by some competitors, the nipple actually threads into the hose and is retained by the socket. The thread forms 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 eliminating the risk of leaking.
