A 3/4 inch copper 90 degree close rough elbow fitting with a smooth metallic finish and curved tube shape

Mueller Industries, Inc.

Mueller Industries, Inc. 2634 3/4" Copper 90° Close Rough Elbow

SKU CH-4ZTT-BBPN2

A 90-degree close rough elbow joins 3/4-inch copper tubes in plumbing systems with a 582 psi pressure rating at 100 degrees F and an operating range from -20 to 400 degrees F

  • 90° close-rough elbow enables tight copper pipe turns
  • Wrought copper construction resists corrosion in plumbing systems
  • Rated 582 psi at 100 °F for high-pressure lines
  • Operates from -20 °F to 400 °F across temperature extremes
  • Manufactured to ASME B16.22 in an ISO 9001 facility

Application and Purpose

This 3/4 inch copper 90 degree elbow joins two tube ends of the same size in a tight radius. It suits plumbing and hydronic installations where a compact directional change is required. The fitting is manufactured from wrought copper for reliable solder joints.

Suitability and Limits

Installers needing a close-radius turn in 3/4 inch copper tubing will find this part matches the required dimensions and pressure rating. Systems that demand a longer sweep radius or a different connection type should select an alternative fitting style. The temperature range covers typical heating and cooling circuits.

Deciding Specification

The fitting conforms to ASME B 16.22 and is rated for 582 psi at 100 degrees F. This pressure and temperature rating determines whether the elbow meets the design conditions of the intended piping system.

Questions about this item

Will the 582 psi rating hold if the line runs at 400 Degrees F all day?

The fitting is rated for 582 psi at 100 Degrees F; pressure capacity decreases as temperature rises toward the 400 Degrees F limit, so verify the derating curve for continuous high-temperature service.

What pipe and tools are needed to join this 3/4 in FTG x FTG elbow?

You need 3/4 in nominal copper tube (7/8 in OD), flux, lead-free solder, a torch, and cleaning tools to make sweat joints on both FTG ends.

Can this wrot copper elbow connect directly to an older threaded brass adapter?

No, both ends are FTG sweat sockets for copper tube; a separate male or female adapter fitting is required to transition to threaded connections.
