This small but critical fitting creates the leak-tight mechanical seal where tubing or a metering connection passes through the coil assembly. The correct seal and matching nut maintain the system's pressure integrity and prevent refrigerant or condensate leakage at the joint. Worn or missing seals are a common source of slow leaks during coil or flowrator service.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: B1796632\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (fits Amana equivalents)\u003c\/li\u003e\n\u003cli\u003eSize: 3\/8 inch\u003c\/li\u003e\n\u003cli\u003eIncludes: Seal and matching nut\u003c\/li\u003e\n\u003cli\u003eFits: ARUF042-00A-1B series air handlers\u003c\/li\u003e\n\u003cli\u003eFunction: Leak-tight tubing\/fitting seal\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003egenuine Goodman OEM\u003c\/strong\u003e seal and nut are sized to the exact thread pitch and bore of the ARUF042 connection.
