It features NPT end connections and carries a Class 125 pressure rating of 125 psi, making it suitable for low-to-medium pressure water, air, and compatible fluid service lines. The red brass construction provides solid corrosion resistance in wet environments. Unions allow two pipe sections to be disconnected and reconnected without rotating either pipe, which is a common requirement during equipment service and system maintenance. Licensed plumbers and pipefitters install this fitting as a standard component in commercial and residential piping layouts.\u003c\/p\u003e\n\u003cp\u003eThis union fits into 1\/2 inch NPT threaded pipe systems where a break-apart connection point is needed. Typical applications include water supply lines, compressed air distribution, hydronic heating loops, and light industrial fluid piping operating within Class 125 service conditions. The fitting is sold individually and is appropriate for both new installation and replacement work in maintenance and repair scenarios.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2 inch NPT threaded end connections on both sides\u003c\/li\u003e\n  \u003cli\u003eClass 125 rated to 125 psi working pressure\u003c\/li\u003e\n  \u003cli\u003eRed brass construction for corrosion resistance in wet and humid environments\u003c\/li\u003e\n  \u003cli\u003eUnion design allows pipe disconnection without rotating pipe sections\u003c\/li\u003e\n  \u003cli\u003eCompact form factor at 2.75 inches tall and 1.75 inches in diameter\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or new-installation fitting for 1\/2 inch NPT threaded pipe systems rated at Class 125 or lower service conditions.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed plumbers or qualified pipefitters following applicable IPC or local plumbing code requirements. Shut off and depressurize the affected pipe section before disassembly or installation. Apply an appropriate thread sealant or PTFE tape to the NPT threads before assembly.
