Overall Assessment

Customers vouch for the product's effectiveness and quality, with many noting it perfectly met their needs. They often experienced no leaks, marking it as reliable, and some even dubbed it the "exact adapter" they required. It earned praise for its usability and compatibility, even with unusual or specific fittings. Reviewers commended the safety it brought to brake line jobs and called it an excellent solution for adding brake light function. Assertions of its superior material quality and precise fit also often appeared. Despite some minor criticism about needing modifications or the fit, the product stands out with an overwhelmingly positive reception.

Works good

Nice adapter and as works described for use with my PV2 proportioning valve and hydraulic stoplight switch. This adapt allowed me to install the stoplight switch. No issues. Thank you. *4 stars due to Speedway's continued lack in information and discounts.

Most Liked Negative Review

2.0

Too short of threads

Threaded into the master cylinder but ran out of threads before it was able to make a seal on the inverted flare, not to mention that the inverted flare didn't look right either. Being that these are non-sealing threads, a crush washer must be used (as long as the port on the master cylinder has a machined surface). Speedway was good about getting me the crush washer after I raised this concern with them.
