Fragola -6AN x 18mm x 1.5 O-Ring Adapter Fitting - Steel

This is a Fragola -6AN to 18mm x 1.5 O-ring adapter fitting, made from steel. It's used to connect different types of fittings in custom plumbing setups, like fuel lines or vacuum lines, where you need to adapt from a standard AN fitting to a metric O-ring boss. The steel construction means it's built to handle common automotive fluids and pressures.

This fitting allows you to bridge the gap between AN-style plumbing and metric threaded ports that use an O-ring seal. The -6AN size is a common standard in aftermarket fuel and oil systems, while the 18mm x 1.5 thread is often found on factory components or specific aftermarket parts. Using the right adapter ensures a leak-free connection, which is crucial for maintaining proper fluid flow and preventing fuel or oil leaks.
