ProPress 45° Elbow 3/4

This copper press-fit elbow joins two 3/4-inch copper tubes at a 45-degree angle. It is designed for potable water systems and meets ASTM B75 and ASTM B88 standards. The fitting uses EPDM O-rings for a watertight seal without soldering.

Copper construction with press connections

The copper body resists corrosion and handles a maximum operating pressure of 200 psi and a maximum operating temperature of 250 degrees F. Both ends feature press-fit connections that require a compatible press tool, eliminating the need for open flame or flux on site.

Supplied as a single fitting

No additional rings, tools or lubricant are included in the package. Installers must provide a calibrated press tool and jaws matched to the 3/4-inch size. Buyers who need straight couplings, tees or other angles will need to source those fittings separately.
