Stainless Steel Duolok Tube Fitting, 0.75 Inch Tube OD Cap

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.

For a 0.75 inch tube OD line, this Duolok cap is made to terminate the open end with a secure, leak tight closure in instrumentation and process tubing systems.
