Viega 49780 Test Plug 1-1/2 Inch Press End Polymer

Product Description

The VIEGA 49780 is a polymer test plug designed for use in PureFlow Press piping systems at the 1-1/2 inch nominal pipe size. It installs with a press end connection, allowing technicians to temporarily seal a pipe end during pressure testing without the need for threaded fittings or solvents. The polymer construction keeps the fitting lightweight and corrosion-resistant. Licensed plumbers and pipefitters use this plug during rough-in inspections and system commissioning to verify pressure integrity before a piping system is placed into service.

This test plug is intended for PureFlow Press installations in residential and light commercial plumbing applications. It is well suited to new construction and retrofit projects where press-style connections are the specified joining method. The press end style allows the plug to be installed quickly with standard press tooling, making it practical for time-sensitive pressure-test sequences on multi-fixture systems.

Key Features

• 1-1/2 inch nominal size fits standard PureFlow Press pipe
• Press end connection style — no threads, solder, or solvent cement required
• Polymer construction resists corrosion and keeps weight low
• Temporary plug design supports pressure testing during system commissioning
• Domestic product sourcing

Compatibility

Designed for use with VIEGA PureFlow Press systems at the 1-1/2 inch nominal pipe size using a press end connection style.

Installation Notes

Installation should be performed by a licensed plumber familiar with press-fit piping systems and local plumbing code requirements under the IPC or applicable jurisdiction. Verify that all upstream supply is isolated and the system is depressurized before installing or removing the test plug. Use only the press tooling specified for the PureFlow Press system to make the connection. Remove the test plug and inspect the press joint after testing is complete before returning the system to service.
