It seals the joint between the exhaust manifold and riser, and its restricted design controls exhaust and cooling water flow through that joint to the manufacturer's original specification. This gasket is one of three dry-joint gasket styles Sierra offers for this application - open, closed, and restricted - so it is important to confirm that a restricted style is the correct replacement for your engine before ordering.\u003c\/p\u003e\u003cp\u003eThe 18-0722 is intended for use with Sierra's dry-joint manifold (Sierra Part Number 18-1843) and riser (Sierra Part Number 18-1845), and it is also listed alongside Sierra's dry-joint elbow gaskets 18-0720 and 18-0721 as part of the same gasket family. It directly replaces Mercruiser part numbers 27-864850A02 and 27-864850A01, making it a straightforward like-for-like swap when servicing the exhaust manifold-to-riser joint. The gasket is round in shape and finished in white.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 18-0722\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGasket Style:\u003c\/strong\u003e Restricted\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape:\u003c\/strong\u003e Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.25 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282359461\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUsed With:\u003c\/strong\u003e Sierra Manifold 18-1843 and Sierra Riser 18-1845\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelated Dry-Joint Elbow Gaskets:\u003c\/strong\u003e 18-0720 (Closed), 18-0721 (Open)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e 4.3L Alpha\/Bravo (2002 and Newer without Engine Catalyst)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eFits 4.3L Alpha\/Bravo applications, 2002 and newer, without engine catalyst.
