This washer-style sealing component provides a secure, leak-resistant interface between the gauge glass and its fittings. With an inside diameter of 0.781 inches, an outside diameter of 0.940 inches, and a thickness of 0.031 inches, this ring is precision-sized for consistent fitment. Each pack contains 12 rings, making it practical for service trucks and maintenance stock. Installation is handled by licensed boiler technicians and steam fitters during gauge glass service or replacement.\u003c\/p\u003e\n\u003cp\u003eThis friction ring is suited for residential and light commercial boiler systems where gauge glass visibility and sealing integrity are critical. It is a common consumable used during gauge glass replacement, routine boiler maintenance, and pressure vessel servicing. The 12-piece pack quantity supports efficient service calls and reduces return trips for additional parts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBrass construction for corrosion resistance in wet steam environments\u003c\/li\u003e\n  \u003cli\u003eInside diameter of 0.781 inches for precise gauge glass fitment\u003c\/li\u003e\n  \u003cli\u003eOutside diameter of 0.940 inches with a 0.031-inch thickness\u003c\/li\u003e\n  \u003cli\u003ePack of 12 rings for convenient service stock\u003c\/li\u003e\n  \u003cli\u003eFriction-fit design seats securely without additional fasteners\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement friction ring for gauge glass assemblies on residential and commercial boiler and steam systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed boiler technician or steam fitter. Shut down the boiler and allow the system to depressurize and cool fully before servicing the gauge glass assembly. Inspect the gauge glass fitting seating surfaces for wear or corrosion before installing new friction rings.
