Overall Assessment

Customers have praised our product for its quality, usability and secure fit. Many found it perfect for their specific projects, emphasizing that it "worked as it was designed for" and made "hooking everything up so much easier". The product's material is recognized for durability, with some customers appreciating the "good brass", unlike other inferior materials in the competition. However, one review mentioned it being a soft material prone to squishing. Despite that, the majority of customers confirmed that it "doesn't leak" unlike other products, enhancing the safety and efficiency of their brake systems. Many recommend the product, vowing to repurchase for future projects. There was a complaint about a leak, though the problem appears resolved, with a minority repurchase hesitation due to incidental shipping delay.

Pretty handy adapter.

Accidentally screwed up the threads on my clutch master cylinder. Tapped the 3/8-24 port to 1/8" NPT and used an adapter. Saved me from having to replace a very hard-to-find master cylinder. Could also be used to make a line lock using a 1/8" NPT ball valve.

Leaked

Speedway sent out two because the first one leaked, no matter how tight I installed it on the residual valve.

I used this fitting to adapt the brake pedal assembly I bought from Speedway to my 1931 Chevy hot rod car and it worked great!
