This fitting transitions from a 1-1\/2 inch female thread to a 1\/2 inch male thread and is finished in black iron. It is a standard pipe fitting used in gas piping, water distribution, and mechanical systems. Plumbers and pipefitters install these bushings when adapting between different pipe diameters within a threaded pipe assembly. The hex design allows for a wrench to apply proper torque during installation. Each package contains 5 units, making it suitable for multi-connection jobs or service stock.\u003c\/p\u003e\u003cp\u003eThis hex bushing is used in residential and light commercial plumbing and gas piping applications. It fits into standard threaded pipe systems where a size reduction is needed without adding a nipple and coupling combination. Typical install scenarios include gas appliance rough-ins, water supply lines, and general mechanical piping where NPT threaded fittings are required. The black iron finish makes it well suited for gas service applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eReduces 1-1\/2 inch female NPT to 1\/2 inch male NPT in a single fitting\u003c\/li\u003e\n\u003cli\u003eBlack iron finish suitable for gas piping service\u003c\/li\u003e\n\u003cli\u003eHex body design allows wrench engagement for secure installation\u003c\/li\u003e\n\u003cli\u003eSold in a package of 5 units for multi-connection jobs\u003c\/li\u003e\n\u003cli\u003eStandard threaded bushing for use in NPT pipe systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard-use fitting for any threaded NPT pipe system requiring a 1-1\/2 inch to 1\/2 inch bushing reduction.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed plumbers or pipefitters working on threaded pipe systems.
