ROADFORMER 3.25in T-Bolt Hose Clamp 2-Pack — 78–86mm Range, 304 Stainless & Nylon Locknut

This pair of heavy-duty T-bolt clamps is built for applications that demand consistent clamping pressure and long-term corrosion resistance. Each clamp fits hoses with a 3.25" outer diameter (working range 78mm–86mm), and combines a 304 stainless band, stainless bolt, floating bridge and nylon-insert locknut to resist vibration loosening and provide a uniform seal. The clamps are suitable for automotive, agricultural, industrial and off-road use where reliability under load matters.

How do these clamps create a reliable seal on a 3.25" hose?

The T-bolt design spreads tightening force evenly around the hose circumference, minimizing deformation and gaps that cause leaks. The floating bridge aligns the band and transfers torque from the bolt across the band for consistent pressure. The nylon-insert locknut resists backing off under vibration.

• 78–86mm working diameter matches a 3.25" hose outer diameter.
• 304 stainless steel band for corrosion resistance.
• Floating bridge ensures even load distribution.
• Nylon-insert locknut prevents loosening in vibration.

What materials and parts are used, and why do they matter?

These clamps use corrosion-resistant components engineered to extend service life in harsh environments. The band and bridge are 304 stainless steel, while the bolt is stainless as well, reducing rust risk. The nylon insert adds mechanical locking to keep tension during repeated cycles.

• 304 stainless steel band and bridge for durability and rust resistance.
• Stainless T-bolt provides reliable clamping torque and longevity.
• Nylon locknut secures tension under vibration and thermal cycling.
• Simple mechanical design minimizes maintenance needs.

How easy is installation and what tools are required?

Installation is straightforward: slip the clamp over the hose, position it on the fitting, then tighten the bolt to the desired tension. No special tools are necessary—standard hand tools like a wrench or socket will do. The floating bridge helps keep the band centered while you tighten.

• Slide clamp over hose and position to cover the fitting.
• Tighten bolt with a wrench or socket until snug and leak-free.
• Re-check torque after system pressurization or initial use.
• Designed for quick field replacement with common tools.

Will these clamps work where vibration and pressure are high?

Yes. The combination of uniform band compression, a strong T-bolt, floating bridge and nylon locknut helps maintain clamp tension in high-vibration and higher-pressure situations. They are intended for environments where clamps must hold reliably over time.

• Uniform sealing pressure reduces risk of leaks under stress.
• Locknut prevents gradual loosening from vibration.
• Stainless construction resists corrosion in wet or salty environments.
• Commonly used on heavy trucks, industrial hoses and off-road equipment.

Who this is for: Installers, mechanics, fleet managers and DIYers who need dependable hose connections for automotive, agricultural, industrial or off-road systems. Choose these ROADFORMER T-bolt clamps when you require a rust-resistant, vibration-proof clamp sized for a 3.25" hose outer diameter and prefer a ready-to-install 2-pack for repairs or spares.
