these fit standard -06 SAE flared fittings or is there a specific type they work with?

Question by: Rod C on Oct 15, 2025, 6:08 PM

Flared fittings with a 5/8-18 thread size are what these caps are built for. The -06 SAE designation covers that exact thread, so as long as your fitting matches that spec, you should be good to go. They thread on securely to keep contaminants and mechanical damage from getting to the fitting face while it's not in service.
