got a small inverted flare line i need to cap off, is this the right plug for 3/16 tube
Answer by: Customer Support on Oct 31, 2025, 6:39 AM
For a 3/16 inch tube size, this plug matches up with a 0.1875 inch tube outer diameter and uses a 42 degree male inverted flare sealing surface, so it’s suited for capping that style of inverted flare connection.
