Copper reducing elbow for plumbing systems

This 90-degree close rough elbow connects 3/4 inch and 5/8 inch copper tubes using C x C fittings. It is made from wrot copper alloy C12200 and meets ASTM B75 standards for reliable solder joints in residential and commercial installations.

Pressure rating and temperature headroom

The fitting handles up to 466 psi at 200 degrees Fahrenheit and operates across a range of -20 to 400 degrees Fahrenheit. This capacity covers typical hot water, hydronic heating and medical gas lines, while pressures above the rated maximum or temperatures beyond 400 degrees Fahrenheit exceed its design limits.

Certified for potable water and medical gas

Third-party certification to NSF/ANSI 61 Annex G confirms suitability for drinking water systems. Compliance with ASME B16.22, MSS SP-104, MSS SP-109 and NFPA 99 supports use in healthcare gas and vacuum pipelines. The copper construction resists corrosion under normal operating conditions without requiring external power or moving parts.

Questions about this item

Will the 3/4 in x 5/8 in C x C ends fit the copper tubing I already have in the house?

Yes, the fitting is made for 3/4 in and 5/8 in nominal tube sizes with an outside diameter of 7/8 in x 3/4 in, so it solders directly to standard copper pipe of those dimensions.

How can I confirm the joint is sound after I solder it?

Pressure-test the system up to the rated 466 psi at 200 °F; a leak-free hold at working pressure shows the 90-degree elbow is performing to its ASME B16.22 and MSS SP-104 design limits.

Does the box include flux, solder or any extra adapters for the 3/4 x 5/8 in connection?

Only the wrought-copper reducing elbow is supplied; flux, solder and any transition fittings must be purchased separately.
