For a -16 JIC flared fitting that uses 1-5/16-12 threads, this protective threaded plug is the matching size. It is a polyethylene (LDPE) plug meant to thread on and cover the fitting threads.

Does this plug actually hold without any thread tape or sealant, or is that something I'd need to add on my end?

Answer by: Customer Support on Feb 27, 2026, 7:45 PM

For flared fittings, no sealant is needed. The plug is precision molded to match the 1-5/16-12 thread profile on JIC flared fittings, and that geometry is what creates the seal. Thread tape or compound would actually be out of place here since flared connections rely on metal-to-metal or fitting-to-plug contact, not sealant.
