Generic T-Bolt Hose Clamps 70–78mm for 2.5" Hoses — 10-Pack, 301 Stainless Heavy-Duty

Heavy-duty 301 stainless steel T-bolt clamps sized 70–78mm (2.76"–3.07") sold as a 10-piece set for secure, leak-resistant clamping of 2.5" (63mm) inner-diameter silicone hoses.

These T-bolt clamps are engineered to deliver a uniform sealing force for air-intake, turbo, and intercooler plumbing where a stronger, more reliable hold is needed than standard worm-gear clamps provide. Built from 301 stainless steel with zinc-coated fasteners and rounded band edges, this pack of ten clamps is designed for repeated installation and high-temperature, high-pressure service on automotive, truck, and heavy-equipment hoses.

How do these T-bolt clamps differ from regular screw-style hose clamps?

T-bolt clamps use a bolted fastening design that spreads clamping force evenly around the hose circumference, reducing localized stress and the chance of leaks. The bolt-and-stud assembly allows higher torque and a more consistent seal, which is especially useful on thick silicone couplers and high-pressure lines.

• 301 stainless steel band and zinc-coated nut for corrosion resistance.
• 19 mm band width and 0.6 mm thickness for heavy-duty applications.
• Rounded band edges protect soft silicone from cuts and abrasion.
• Clamping range 70–78 mm (2.76"–3.07") fits typical 2.5" hoses with appropriate wall thickness.

What hose sizes and materials will fit these clamps?

The clamps cover an outside diameter window from 70 mm to 78 mm, intended for hoses with a 63 mm (2.5") inner diameter and wall thickness roughly between 4 mm and 11 mm. To confirm fit, add twice your hose wall thickness to the inner diameter to calculate the outside diameter and compare it to the clamp range.

• Designed for silicone intake or intercooler hoses, and reinforced couplers.
• Fits hoses with 63 mm inner diameter and up to approximately 73 mm outer diameter when thick-walled.
• Temperature tolerance from -65°F to 500°F supports most engine bay conditions.
• Pressure rating approximately 120–275 PSI depending on setup and hose material.

How durable and serviceable are these clamps in real use?

Made from 301 stainless steel with a fine buffed finish, these clamps resist corrosion and maintain tensile strength under repeated use. The bolt-and-stud configuration lets you disassemble and reinstall without losing clamping integrity, making them suitable for maintenance and turbo/intercooler upgrades.

• Heavy-duty construction for long-term resistance to vibration and pressure cycles.
• Can be removed and reused during routine service or part swaps.
• Rounded edges reduce hose damage during high-torque tightening.
• Sold in a 10-piece pack for multi-point installations or spares.

What should I know about installation and safety?

Professional installation is recommended to ensure correct torque and avoid overtightening, which can damage hoses despite the rounded band edges. No installation instructions are included, so use appropriate tools and follow hose manufacturer torque guidance where available.

• Install without disconnecting piping where accessible, but check sealing after first heat cycles.
• Use a calibrated torque wrench or feel for even tightening; avoid sharp over-torque.
• Verify hose outside diameter fits within 70–78 mm before purchase.
• Replace clamps that show deformation, thread damage, or significant corrosion.

Who this is for: Mechanics, tuners, fleet technicians, and DIY enthusiasts who work on turbo, intercooler, or heavy-duty coolant and intake plumbing and need a reliable, reusable clamp solution. This 10-pack gives spare clamps for multi-point installations, frequent service intervals, or shop inventory, and is best chosen when hose outer diameters fall inside the specified clamp range.
