The hose is constructed of black PVC (polyvinyl chloride) supported internally by an anodized wire helix, which keeps the hose round and open while allowing it to flex and route through tight compartments. It is resistant to UV and ozone exposure, making it suitable for the marine environment where hoses are subjected to sun, heat, and engine-bay conditions over time.\u003c\/p\u003e\u003cp\u003eThis hose line is sold in 10 foot lengths and is available in two inside diameters to match different blower and ducting hookups. The hose carries the Sierra part-number stem 16-402 and is a direct replacement or upgrade hose for boats that need to route ventilation ducting between the blower and the bilge or engine compartment.\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 16-402\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Polyvinyl Chloride (PVC) with anodized wire helix support\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 10 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter Range:\u003c\/strong\u003e 3 inch to 4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter Range:\u003c\/strong\u003e 3 1\/8 inch to 4 1\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Use:\u003c\/strong\u003e Venting bilge fumes and blower ducting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUV and Ozone Resistance:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.65 pounds (3 inch) to 0.75 pounds (4 inch)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSizes \u0026amp; Options\u003c\/h3\u003e\u003cp\u003eChoose the hose that matches the inside diameter of your existing blower fitting or ducting run: the 3 inch ID hose (outside diameter 3 1\/8 inch) or the 4 inch ID hose (outside diameter 4 1\/8 inch).
