got a Midland S61 compression fitting body already, is the S61-6 nut the right replacement for 3/8 tubing?

Question by: Diane S on Feb 28, 2026, 10:37 AM

Within Midland’s S61 compression fitting series, the S61-6 is the 3/8 in. compression nut meant to thread onto the fitting body and clamp the ferrule for a leak resistant compression seal on 3/8 in. tubing.
