Viega 26055 MegaPress 90 street elbow 3/4" x 3/4" bathware

Application and sizing

This is a zinc nickel-plated steel crimp elbow fitting designed for non-potable water systems. It connects a 3/4-inch press-fit pipe to a 3/4-inch copper tube size FTG connection in a 90-degree street elbow configuration. The fitting carries an EPDM O-ring and is rated for a maximum operating pressure of 200 psi and a maximum operating temperature of 250 degrees Fahrenheit. It suits installers needing a durable press-to-FTG transition.

Pre-installation checks

Verify that the existing piping matches the 3/4-inch press-fit and 3/4-inch copper tube size dimensions before ordering. Confirm the system fluid is non-potable water and that operating conditions stay within the 200 psi and 250 degrees Fahrenheit limits. Ensure the installation tooling is compatible with the press-fit connection type and that the EPDM O-ring material is suitable for the specific application environment.

Thermal and pressure performance

In normal use the fitting withstands continuous temperatures up to 250 degrees Fahrenheit without degradation of the zinc nickel-plated steel body or the EPDM seal. The 200 psi pressure rating provides a solid margin for typical non-potable water circuits. The press-fit joint eliminates open-flame work, reducing installation time and avoiding heat-affected zones on adjacent pipework. No moving parts mean silent operation.
