Question by: Earl M on Apr 24, 2025, 11:39 AM

Match it to a -20 JIC flared fitting with 1-5/8-12 threads. This cap is a polyethylene protective threaded cap made for that -20 JIC size and thread.

what thread size is this cap, and is it meant for JIC flared fittings specifically?

Question by: Brent R on Mar 15, 2026, 4:46 PM

fits right onto a 1-5/8-12 thread, which is the standard thread for a -20 JIC flared fitting. These caps are made for protecting the flared end during storage or shipping so the seating surface doesn't get dinged up before the fitting ever gets put to use.

Question by: Daryl F on Jan 14, 2026, 7:50 AM

Correct fit. The cap is threaded at 1-5/8-12, which matches the -20 JIC standard. No thread sealant is included or needed, so it threads straight onto compatible flared fittings without any prep work.
