ProPress 45° elbow for copper tube

The Viega 77033 ProPress fitting joins two 1-1/4" copper tubes at a 45-degree angle using press-fit connections on both ends. It is designed for potable-water systems and carries ASTM B75 and ASTM B88 compliance. The copper body uses an EPDM O-ring for a permanent, leak-free seal without soldering. Installers working on commercial or residential plumbing projects will find it suited for new installations and repairs.

Check tube size and system pressure

Verify that both pipe ends are 1-1/4" copper tube sized to ASTM B88 dimensions before ordering. The fitting is rated for a maximum operating pressure of 200 psi and a maximum operating temperature of 250 degrees F. Ensure your pressing tool and jaw set are approved for Viega ProPress copper fittings in this diameter. The product is not restricted for sale in any listed state.

EPDM O-ring and press-fit design

The factory-installed EPDM O-ring eliminates the need for flux, solder or open flame during assembly. Pressing creates a mechanical bond that is immediately pressure-testable and reduces installation time compared with traditional sweat connections. No additional sealing compounds or gaskets are supplied or required. The copper construction resists corrosion in potable-water applications.

Questions about this item

What comes in the box with the Viega 77033 ProPress 45° elbow, and is any tooling or sealing material sold separately?

The fitting is supplied as a single copper elbow with an EPDM O-ring already installed; a compatible ProPress press tool and jaw set must be purchased separately to complete the connection.

How do I decide between the available ProPress 45° elbows when the only difference shown is the 1-1/4" × 1-1/4" size?

Choose this 77033 model when both pipe ends are 1-1/4" copper tube; other listed ProPress elbows differ only in tube diameter, so match the fitting to your pipe size.

What does the 200 psi pressure rating mean once the elbow is pressed into a potable-water system?

The joint is rated for continuous operation at up to 200 psi and 250 °F, meeting ASTM B75 and ASTM B88 standards for potable-water service.
