got a line with a 45 degree flare seat. is this the little brass plug that’ll cap it off without me messing with tape or dope

For a 45 degree SAE flare connection, this adapter is meant to make the seal at the flare, so you do not need thread sealants to get a solid seal. It is a brass SAE 45 flare union style plug with a 0.63 inch outside diameter and a 0.875 inch UNF male end.

Hey, will this plug work okay with a standard SAE 45 degree flare?
Answer by: Customer Support on Jun 27, 2025, 11:19 AM
You bet, this SAE 45 Flare Union is designed specifically for that type of connection, ensuring a solid seal without needing any thread sealants.
Question by: Johnny H on Nov 25, 2025, 5:53 PM
does this plug need any thread sealant or tape to seal up right, or does the flare handle all that on its own?
Answer by: Customer Support on Nov 27, 2025, 6:58 AM
The 45-degree flare does the work here. Brass flare fittings like this one create their seal through metal-to-metal contact at the flare seat, so thread sealants and tape are not needed and honestly not recommended. A clean, properly seated connection is all it takes.
