Viega VIEGADFTGFIP114 Propress Bronze Pipe Adapter

Product Description

The VIEGA VIEGADFTGFIP114 is a lead-free bronze pipe adapter designed for use with the ProPress press-fitting system. It transitions from a ProPress press-fit connection on one end to a female NPT (FNPT) threaded connection on the other, allowing technicians to join press-fit copper piping to threaded pipe or threaded equipment connections. Rated for 200 psi and a temperature range of 0 to 250 degrees F, this adapter suits a wide range of commercial and residential plumbing and hydronic applications. The 1-1/4 inch nominal size and bronze construction make it a reliable choice for pressurized water systems where lead-free materials are required by code.

This adapter is used in plumbing, mechanical, and hydronic heating systems where ProPress copper press fittings interface with threaded components such as valves, pumps, or manifolds. At 2.19 inches in length, it is compact enough for tight mechanical spaces. Plumbers and pipefitters installing press-fit copper systems will encounter this fitting when connecting to threaded isolation valves or equipment flanges. It is suited for both new construction and retrofit work where press-fit tooling is already on site.

Key Features

• Lead-free bronze construction meets code requirements for potable water systems
• ProPress press-fit inlet eliminates open flame and torch work at the fitting connection
• Female NPT (FNPT) outlet threads onto standard pipe and threaded equipment
• Rated to 200 psi for pressurized water and hydronic applications
• Temperature range of 0 to 250 degrees F covers chilled and hot water service
• Compact 2.19-inch length fits in confined mechanical spaces

Compatibility

Designed as an OEM-style replacement and standard component for 1-1/4 inch ProPress copper press-fitting systems in residential and commercial plumbing and hydronic piping installations.

Installation Notes

Installation requires a calibrated ProPress pressing tool with the appropriate jaw size for 1-1/4 inch fittings on the press-fit end; the FNPT end is installed using standard pipe thread practices with an approved thread sealant or PTFE tape. Shut off and depressurize the water system and drain the line before pressing or threading any fitting. Work must comply with applicable local plumbing codes, which may reference IPC or IFGC standards for approved joining methods and materials. Verify the pipe is clean, round, and fully inserted to the depth mark before pressing.
