The Mega-Flow design uses thin-wall construction to maximise the internal bore relative to the hull opening, while a drip collar on the face of the fitting channels water away from the hull surface to prevent the staining and streaking common with standard thru-hulls. A machined inner finish reduces the potential for debris accumulation inside the tube. Includes a watertight gasket. Suited to gray-water discharge applications including cockpit drains, sink outlets, and bilge pump discharges.\u003c\/p\u003e\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\u003cp\u003eThis is the correct fitting when you need a 5\/8\" hose thru-hull in hulls up to 1-1\/2\" thick and want a stainless-steel finish that resists corrosion and looks good at the waterline. The drip collar is a practical feature on boats where hull streaking from discharge fittings is a cosmetic concern — particularly on white or light-coloured hulls. The thin-wall Mega-Flow design is well-suited to gray-water applications where flow rate matters, such as cockpit drains and sink outlets. Confirm your hose ID is 5\/8\" and your hull thickness does not exceed 1-1\/2\" before ordering. This fitting is available in multiple hose sizes — see the related products below for 3\/4\", 1\", 1-1\/8\", and 1-1\/2\" hose variants.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMaterial: 316 polished stainless steel\u003c\/li\u003e\n\u003cli\u003eHose size: 5\/8\" ID\u003c\/li\u003e\n\u003cli\u003eMaximum hull thickness: 1-1\/2\"\u003c\/li\u003e\n\u003cli\u003eFlange diameter: 1-1\/4\"\u003c\/li\u003e\n\u003cli\u003eFeatures: Drip collar, thin-wall Mega-Flow bore, machined inner finish\u003c\/li\u003e\n\u003cli\u003eIncludes: Watertight gasket\u003c\/li\u003e\n\u003cli\u003eIdeal applications: Gray-water discharge, cockpit drains, sink outlets, bilge pump discharge\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOther Sizes in This Range\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/seachoice-mega-flow-dripless-thru-hull-fitting-316-stainless-steel-fits-3-4-in-hose-1-1-2-in-max-hull\"\u003eSeachoice Mega-Flow Dripless Thru-Hull Fitting — 316 SS, 3\/4\" Hose\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/seachoice-mega-flow-dripless-thru-hull-fitting-316-stainless-steel-fits-1-in-hose-1-1-2-in-max-hull\"\u003eSeachoice Mega-Flow Dripless Thru-Hull Fitting — 316 SS, 1\" Hose\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/seachoice-mega-flow-dripless-thru-hull-fitting-316-stainless-steel-fits-1-1-8-in-hose-1-1-2-in-max-hull\"\u003eSeachoice Mega-Flow Dripless Thru-Hull Fitting — 316 SS, 1-1\/8\" Hose\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/seachoice-mega-flow-dripless-thru-hull-fitting-316-stainless-steel-fits-1-1-2-in-hose-1-1-2-in-max-hull\"\u003eSeachoice Mega-Flow Dripless Thru-Hull Fitting — 316 SS, 1-1\/2\" Hose\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eRelated Products\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/seachoice-covered-thru-hull-fitting-w-stainless-steel-flange-fits-3-4-in-id-hose\"\u003eSeachoice Covered Thru-Hull Fitting with Stainless-Steel Flange — 3\/4\" ID Hose\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/seachoice-thru-hull-strainer-mount-with-aerator-screen-3-4-hose\"\u003eSeachoice Thru-Hull Strainer Mount with Aerator Screen — 3\/4\" Hose\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LNS","offers":[{"title":"Default Title","offer_id":51199424036900,"sku":"50-18591","price":62.34,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/images_240fad47-c916-4604-89b5-f5f93117bee0.jpg?v=1785794579","url":"https:\/\/marisolmarine.com\/products\/seachoice-mega-flow-dripless-thru-hull-fitting-316-ss-5-8-hose-50-18591","provider":"Marisol Marine Company","version":"1.0","type":"link"}
