Copper Tube Stop Coupling
This sweat fitting coupling joins two 3/8 inch nominal copper tubes in a straight line. It is designed for air, gases and potable water systems in residential and commercial plumbing. The wrot copper construction provides corrosion resistance for long service life.
779 psi Pressure Rating
The coupling withstands a maximum operating pressure of 779 psi at 100 degrees Fahrenheit. This single figure determines whether the fitting suits the pressure demands of the intended piping circuit. Exceeding this limit risks joint failure and leaks.
400 Degree Temperature Headroom
The fitting handles continuous temperatures up to 400 degrees Fahrenheit, covering most hot water and low pressure steam lines. It runs out of headroom in high temperature industrial steam or specialised heat transfer fluids above that threshold.

Questions about this item
What does the 779 psi rating mean for a typical plumbing job?
It means the coupling can handle up to 779 psi at 100 degrees Fahrenheit, well above normal residential supply pressure.
How does the sweat connection affect installation on 3/8 inch copper tube?
Each end is a cup fitting for 3/8 inch nominal tube with a 1/2 inch outer diameter, so you solder it directly to the pipe.
What clearance should I allow for the straight coupling body?
The straight coupling joins two tubes end-to-end in-line, so measure the installed length between the two solder joints.
