Auto-Fit™ Male Pipe Thread Hose Ends
Earl's Auto-Fit™ Male Pipe Thread Hose Ends

Earl's Auto-Fit design provides the reliability and appearance of Swivel-Seal but are easier to assemble and less Auto-Fit Cut Viewexpensive.

With the conventional single nipple hose end design, 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 Swivel-Seal) and there is no spiral path for possible leaks.

Remember: High Pressure Capabilities = Greater Reliability!

When you need to reuse a hose end and the sockets are damaged or worn, you can now order replacement sockets!

Note: Because we deal predominately with motorcycles, we usually only stock -3, -4, and -6 sizes. We can special order anything Earl's offers.

AlertAuto-FitTM hose ends are designed to be used with Perform-O-FlexTM & Auto-FlexTM hose. They are not recommended for use with any other manufacturers' hose. Before purchasing a single-nipple hose end that merely "looks good," check the pressure ratings of Auto-Fit hose ends when used with Perform-O-Flex and Auto-Flex hose.
