{"product_id":"sierra-shieldsflex-ii-marine-water-exhaust-hose-with-wire-available-in-5-8-to-3-id","title":"Sierra Shieldsflex II Marine Water\/Exhaust Hose - Available in 5\/8\" to 3\" ID","description":"\u003cp\u003eSierra Shieldsflex II is a wire-reinforced marine water and exhaust hose built for runs where bends or long lengths are required. It has a black synthetic rubber tube and cover reinforced with a wire helix embedded between plies of heavy-duty synthetic cord, keeping the hose round and kink-resistant through tight routing. It is used for engine intake, bilge pump intake and discharge, scupper lines, wet exhaust connections, toilet intake and discharge, and holding tank vent or pump-out lines aboard boats. The hose resists exhaust fumes, ozone, mild chemicals, antifreeze, and saltwater, and its cover is abrasion and odor permeation resistant. It handles a continuous temperature range of -20 F to +200 F, with intermittent spikes to +250 F, and meets SAE J2006 Type R2 standards with double the ozone resistance the standard requires. Working pressure is rated at 75 PSI with a 220 PSI burst pressure, and the bend radius is 5 times the hose's inside diameter, letting it curve through tight engine compartments and bilges without collapsing. This line is available in inside diameters from 5\/8 inch up to 3 inches, in lengths from 6 1\/4 feet up to 25 feet on a carton reel for the 1 1\/4 inch size, so it covers everything from short exhaust jumpers to long intake or discharge runs.\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 16-250\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Marine water\/exhaust hose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Synthetic rubber tube and cover reinforced with wire helix between plies of HD synthetic cord\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePly:\u003c\/strong\u003e 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter (ID) Options:\u003c\/strong\u003e 5\/8 inch, 3\/4 inch, 1 inch, 1 1\/4 inch, 2 inch, 3 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter (OD) by Size:\u003c\/strong\u003e 5\/8 inch ID: 61\/64 inch OD; 3\/4 inch ID: 1 1\/16 inch OD; 1 inch ID: 1 5\/16 inch OD; 1 1\/4 inch ID: 1 19\/32 inch OD; 2 inch ID: 2 13\/32 inch OD; 3 inch ID: 3.44 inches OD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Options:\u003c\/strong\u003e 6 1\/4 feet, 10 feet, 12 1\/2 feet, 25 feet (carton)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBend Radius:\u003c\/strong\u003e 5 x inside diameter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBurst Pressure:\u003c\/strong\u003e 220 PSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWorking Pressure:\u003c\/strong\u003e 75 PSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Range:\u003c\/strong\u003e -20 F to +200 F continuous, +250 F intermittent\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards Compliance:\u003c\/strong\u003e Meets SAE J2006 Type R2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Uses:\u003c\/strong\u003e Engine intake, bilge pump intake\/discharge, scupper lines, wet exhaust connections, toilet intake\/discharge, holding tank vent\/pump-out\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSizes \u0026amp; Options\u003c\/h3\u003e\u003cp\u003eChoose your inside diameter first to match the fitting, thru-hull, or exhaust outlet the hose connects to, then choose the length needed for the full run, adding extra where the hose will bend.
