ROADFORMER T-Bolt Hose Clamp 1.62"–1.85" O.D. (1.75" Nominal) 2-Pack — 304 Stainless, Nylon Locknut

Roadformer 1.75" T-bolt hose clamps are heavy-duty stainless-steel clamps that secure 1.62"–1.85" (41–47mm) outer-diameter hoses for turbo, intercooler, radiator and coolant connections.

These two-pack T-bolt clamps are built from 304 stainless steel with a floating bridge and nylon-insert locknut, engineered to resist rust and maintain even pressure under vibration and high pressure. They are intended for use on silicone, rubber and reinforced hoses where a wide, reliable sealing band is required. Before ordering, measure the hose outer diameter (O.D.) — not the inner diameter — to confirm fit.

How do these clamps stay secure under high pressure and vibration?

The T-bolt design gives a large contact area and a solid bolt axis that prevents slippage when tightened. The floating bridge lets the band align itself as torque is applied, spreading clamping force evenly across the hose to reduce hot spots and leaks.

• 304 stainless steel band resists corrosion in harsh conditions
• 1/4"-28 stainless bolt provides robust, repeatable tightening
• Floating bridge evens pressure to protect hose material
• Nylon-insert locknut keeps the set torque from backing off

What size hoses will fit these 1.75" clamps?

These clamps are sized for hose outer diameters between 1.62" and 1.85" (41–47mm). That O.D. range corresponds to hoses commonly used on small intercooler lines, intake plumbing and coolant or heater hoses on many vehicles and equipment.

• Check your hose outer diameter (O.D.), not inner diameter (I.D.)
• Fits hoses commonly labeled 1.75" in nominal size when measured externally
• Works well on silicone, rubber, and reinforced hose constructions

How easy is installation and what tools are required?

Installation is straightforward: slide the clamp over the hose, position it over the barb or fitting, then tighten the bolt until the clamp compresses evenly. Common hand tools like a 7/16" or 11mm wrench or a socket will handle the 1/4"-28 bolt; no specialty tools are required.

• Slip-on placement and simple bolt tightening
• Use standard wrench or socket for repeatable torque
• Rounded band edges help prevent hose damage during installation

Where are these T-bolt clamps typically used?

Roadformer T-bolt clamps are specified where a uniform, high-strength clamp is needed: turbocharger hoses, intercooler piping, radiator and coolant hose connections, heavy trucks, and industrial equipment. Their corrosion resistance and locking nut make them suitable for long-term, high-vibration environments.

• Turbo and intercooler charge lines that face boost pressure
• Radiator, heater and coolant hoses in automotive and industrial systems
• Agricultural and off-road machinery exposed to dirt and moisture
• Applications requiring repeated removal and reliable resealing

Who is this for? These Roadformer clamps are aimed at mechanics, performance tuners, fleet maintenance teams and DIYers who need dependable, corrosion-resistant hardware for critical hose connections. If you work on turbo systems, cooling circuits, or heavy equipment and require a wide, sturdy clamp that holds torque under stress, this two-pack of 1.75" T-bolt clamps provides a practical, durable solution.
