3/4 in Straight Copper Coupling

This straight copper coupling joins two 3/4 in copper tubes using sweat cup connections on both ends. It is made from wrought copper and includes a centre stop dimple for consistent insertion depth. The fitting is rated for potable water applications and handles a maximum operating pressure of 582 psi at 100 Degrees F. It suits plumbers and DIYers needing a reliable straight joint.

Suits potable water copper pipework

The coupling fits standard 3/4 in copper tube with 7/8 in outer diameter and operates up to 250 Degrees F. It is not for systems that require threaded, compression or push-fit connections. Builders needing a reducing coupling or a different tube size should look at other fittings. The centre stop helps prevent over-insertion during soldering.

582 psi pressure rating at 100 Degrees F

This pressure rating is the key specification that determines whether the coupling meets the design pressure of the installation. Verify the system pressure does not exceed this value at the operating temperature. The fitting also carries a 250 Degrees F maximum temperature limit for hot water lines.

Questions about this item

How much pressure can the 3/4 inch copper coupling handle continuously at 100°F?

The straight coupling is rated for a maximum operating pressure of 582 psi at 100°F, which is the limit that governs sustained use in potable water systems.

Will the wrot copper fitting overheat or degrade if the water temperature stays near its upper limit all day?

The coupling is rated to 250°F maximum operating temperature, so continuous exposure at or below that level is within its design range for potable water applications.

What size copper tubing must I already have on site for this 3/4 inch CTS coupling to connect properly?

You need 3/4 inch copper tube size tubing, which has a 7/8 inch outer diameter, to match both cup ends of the straight coupling.
