Unions allow piping systems to be disconnected and reconnected without disturbing adjacent sections of pipe, making them essential for service access points in gas and liquid distribution lines. This fitting carries a Class 150 designation and is rated to 300 psi for both liquid and gas service. It meets a broad set of industry standards including EN 10242, FM Approved, GB\/T 3287, GB\/T 7306.2, GB\/T 7307, ISO 228, ISO 7\/1, and is cULus Listed, supporting use in a wide range of commercial and industrial piping applications.\u003c\/p\u003e\n\u003cp\u003eThis union is suited for installation in commercial plumbing, mechanical piping, gas distribution, and fire protection systems where a threaded, separable connection is required. The 4-inch size addresses larger-diameter branch and main line connections typical in commercial mechanical rooms, industrial process piping, and building service gas lines. Its black malleable iron construction and Class 150 rating make it appropriate for both above-ground and accessible interior installations handled by licensed plumbers and pipefitters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-inch threaded end connections for standard NPT pipe assembly\u003c\/li\u003e\n  \u003cli\u003eMalleable iron construction with black finish for durability in gas and liquid service\u003c\/li\u003e\n  \u003cli\u003e300 psi pressure rating suitable for demanding commercial and industrial piping\u003c\/li\u003e\n  \u003cli\u003eClass 150 designation meets widely recognized fitting classification requirements\u003c\/li\u003e\n  \u003cli\u003eCertified to EN 10242, FM, GB\/T 3287, GB\/T 7306.2, GB\/T 7307, ISO 228, ISO 7\/1, and cULus standards\u003c\/li\u003e\n  \u003cli\u003eSingle-piece packaging with no minimum order above one unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for 4-inch threaded malleable iron piping systems in commercial plumbing, mechanical, and gas distribution applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the International Plumbing Code (IPC) or International Fuel Gas Code (IFGC).
