got a -05 JIC flare fitting with 1/2-20 threads. is this the right little plug to cap it off?

Answer by: Customer Support on Jan 26, 2026, 7:02 AM

For a -05 JIC or -05 SAE flared fitting with 1/2-20 threads, this plug is the matching size. It is a polyethylene protective threaded plug meant to cover and protect those flared fitting threads.

Question by: Hank T on Mar 21, 2026, 6:25 AM

these plug on a -5 JIC fitting or does it need to be SAE?

Answer by: Customer Support on Mar 22, 2026, 8:40 PM

Both, actually. The T-4 covers -05 JIC and -05 SAE flared fittings since they share the same 1/2-20 thread spec. One plug works for either port type, so you don't have to stock two separate sizes if you're running a mix of both on the same equipment.

Question by: Hank F on Dec 24, 2025, 6:41 PM

So this just keeps crud out of the threads on my fittings while they're sitting around?

Answer by: Customer Support on Dec 25, 2025, 9:29 PM

Exactly. It's a polyethylene plug made to protect -05 JIC/SAE flared fitting threads, which are sized at 1/2-20.
