Stainless Steel Duolok Tube Fitting, 0.25 Inch Tube OD To 7/16-20 Male SAE O-Ring Boss (Straight Thread O-Ring), 90 deg Elbow

These Duolok fittings are built to provide a dependable, leak-proof connection, even when there's vibration in the system. The double ferrule design is what really helps, as it makes up for any variations in the tubing.

Confirmed interchangeable with Swagelok brand fittings, so swapping them in without reworking your existing setup is exactly what these are built for. The 0.25 inch tube OD side bites down with a double ferrule, and the 7/16-20 male SAE O-Ring Boss thread handles the port connection. If your current line is already running 1/4 inch tube into a straight thread ORB port, this fitting slots right in.

For a 1/4 inch tube run going into a 7/16-20 male SAE O-Ring Boss straight thread port, that matches what this fitting is built for. It is a 90 degree elbow with a 0.25 inch tube OD Duolok compression end on one side and a 7/16-20 male ORB on the other.
