trying to step down from half inch tubing to quarter inch on a pneumatic line, this the right part for that?

Question by: Freddie H on Mar 13, 2026, 4:04 PM

That's what this fitting handles. It connects 0.5 inch OD tubing on one end and reduces down to 0.25 inch OD on the other. Push-to-connect on both ends, so no tools needed to get it seated. Brass construction holds up well in industrial pneumatic setups where you need a solid, leak-free transition between two different tube sizes.

got 1/2 inch OD tube coming in and need to step down to 1/4, is this the right push-to-connect reducer?

Question by: Cheryl L on May 30, 2025, 3:23 PM

Built for stepping tubing down in one fitting, it takes 0.5 inch tube OD on one side and 0.25 inch tube OD on the other, so it works as a 1/2 to 1/4 push tube reducer.
