1-1/4 x 3/4 in Reducing Elbow

This bronze sweat fitting joins 1-1/4 in and 3/4 in copper tubing at a 90-degree angle. It is rated for potable water systems and handles pressures up to 351 psi at temperatures up to 200 degrees F.

Cup-to-cup sweat connections

Both ends accept copper tube for soldered joints, giving a permanent, leak-resistant seal. The bronze body resists corrosion and meets lead-free requirements for drinking water installations.

Questions about this item

What pressure does the 707R-LF sweat fitting handle in practice?

The bronze reducing elbow is rated for a maximum operating pressure of 351 psi at 200 Degrees F.

What copper tube sizes must I have to fit this 1-1/4 x 3/4 in elbow?

Side A takes 1-1/4 in copper tube (1 3/8 in OD) and Side B takes 3/4 in copper tube (7/8 in OD).

How do I install the cup-to-cup joint and what step is often missed?

Clean both tube ends and fitting cups, apply flux, insert tubes fully, then heat evenly and feed solder until the joint rings completely; skipping full insertion or uneven heat leaves voids.
