Nibco H-7-2104w Wp 1 Inch Fpt G-union Adapter

Product Description

The NIBCO h-7-2104w wp is a 1-inch female pipe thread (FPT) to G-union adapter fitting designed for hydronic and plumbing piping systems. This union-style connection allows technicians to make or break a threaded pipe joint without disturbing the surrounding piping, simplifying service work and component replacement. The FPT inlet accepts standard 1-inch NPT-threaded pipe or fittings, while the G-union end provides a secure, leak-resistant mechanical connection. Licensed plumbers and HVAC technicians working on closed-loop heating systems, boiler piping, and similar applications will find this fitting useful where future serviceability is a priority.

This adapter is suited for residential and light commercial plumbing and hydronic heating installations where a threaded union connection is required at a 1-inch pipe size. It is commonly installed at boilers, pumps, water heaters, and other equipment connections that require periodic maintenance or removal. The G-union design allows the piping section to be disconnected cleanly and reassembled without thread sealant re-application on the union joint itself.

Key Features

• 1-inch FPT (female NPT) thread inlet for standard pipe compatibility
• G-union adapter end enables tool-free disconnection at the union joint
• Union design simplifies future service, replacement, or system modifications
• Marketed under the Webstone product line distributed by NIBCO

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1-inch threaded plumbing and hydronic piping systems requiring a G-union adapter connection.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician in accordance with applicable local plumbing codes and the IPC or IFGC as adopted in the jurisdiction. Shut off and depressurize the water or hydronic system and allow it to cool before removing or installing any fittings. Apply an approved thread sealant or PTFE tape to all NPT threaded joints before assembly. Tighten FPT connections to manufacturer-recommended hand-tight-plus turns using appropriate pipe wrenches, and verify no leaks under system pressure before returning the system to service.
