Question by: Dustin C on Feb 28, 2026, 1:44 PM

we run stainless tubing on a few instrument lines and need to cap off some 3/4 inch ends. this the right size for that?

Answer by: Customer Support on Mar 2, 2026, 7:34 AM

For 3/4 inch tube OD, yes, this cap is the correct fit. It's built around that tube size and uses the double ferrule design that compensates for variations in wall thickness and tubing hardness, so you get a reliable seal even if your tubing isn't perfectly uniform. The fitting is machined from 316 stainless steel to ASTM A-276 and A-479 standards, which lines up well with typical instrumentation tubing setups.
