Review on ๐Ÿ”ฉ SYKRSS AN-4 Black 90 Degree Flare Bulkhead Fitting Adapter: High-Quality Anodized Aluminum Construction by Leroy Jacobs

Revainrating 4 out of 5

AN-4 90 degree adapter

This AN-4 90 degree adapter was used on a non-critical oil drain line on a test aircraft. An adjustable wrench was required to tighten the inner nut as it did not fit standard American open-end wrenches. Threads and flare were of good quality and did not leak. Finding an AN-4 size 90 degree adapter is difficult, so I was happy to use it for the given application.

Pros
  • Fuel system
Cons
  • Some small things
