It is designed to fit Shields Series 200 and 250 exhaust hose, with the larger size also suited to Series 202 silicone hose. The band is 316 stainless steel,.025 inch thick and.75 inch wide, chosen for its resistance to corrosion in wet, salt-exposed engine and exhaust environments. The bolt, nut, and trunion are 18-8 (304) stainless steel, and each clamp includes an extra-long 1\/4 inch bolt paired with a nylon insert locknut to resist vibration loosening over time. Each clamp carries a maximum torque rating of 75 inch-pounds, which should not be exceeded during installation to avoid damaging the hose or band.\u003c\/p\u003e\u003cp\u003eThis T-Bolt clamp line is sold as a single product family covering two inside-diameter sizes so boat owners can match the clamp to their exhaust hose without hunting through separate listings. Use it anywhere a standard worm-gear clamp is not robust enough, such as securing large-diameter exhaust hose to risers, mufflers, or through-hull fittings below the waterline.\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 18-720\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 316 stainless steel band; 18-8 (304) stainless steel bolt, nut, and trunion\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBand Thickness:\u003c\/strong\u003e 0.025 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBand Width:\u003c\/strong\u003e 0.75 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBolt:\u003c\/strong\u003e Extra-long 1\/4 inch bolt with nylon insert locknut\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Torque:\u003c\/strong\u003e 75 inch-pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e Shields Series 200 and 250 hose (Series 202 silicone hose for the 6 inch size)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Below-the-waterline marine exhaust hose connections\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAvailable Sizes:\u003c\/strong\u003e 2 inch ID, 6 inch ID\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSizes \u0026amp; Options\u003c\/h3\u003e\u003cp\u003eChoose the clamp by the inside diameter (ID) of the exhaust hose it will secure.
