Designed for marine applications, these 316 Stainless Steel T-Bolt Clamps feature additional corrosion resistance to help keep your hoses clamped without failure, looking clean and rust free for life! Perfect for connecting silicone hoses and exhaust connections on marine boats and skis! Never worry about hoses blowing off under boost pressure or rusty old clamps. These corrosion-resistant T-Bolt Clamps are constructed of 316 Stainless Steel with 316 stainless bolt and nut. They can also be used to secure slip-fit exhaust joints and are proudly made in the USA! Please be sure to measure your silicone or exhaust tube correctly. Please note that our sizes match directly with the Treadstone Silicone Hoses and are oversized .25", so a 3-inch clamp fits a 3-inch hose and will have 0325 on the clamp. The clamp sizes take into account the wall thickness of our silicone and are .25" larger than the specified diameter. If you are using 4 or 5 ply silicone, be sure to order the next size larger. -Designed for salt water marine applications -Increased corrosion resistance, will never rust! -Available in a variety of sizes -Bolt, nut, and band are all 316 Stainless Steel -Made in the USA   View Marine Grade 316 Stainless Steel T-Bolt Clamps
