ROADFORMER T-Bolt Hose Clamp 2.75in (2.56–2.87in O.D.) 2-Pack — 304 Stainless with Nylon-Lock

ROADFORMER 2.75-inch T-bolt hose clamps are heavy-duty 304 stainless steel clamps sized for hoses with a 2.56"–2.87" outer diameter, sold as a 2-pack for high-vibration and high-pressure applications.

These ROADFORMER T-bolt clamps are engineered for demanding hose connections where uniform sealing pressure and corrosion resistance matter. Each clamp uses a 1/4"-28 stainless bolt, a 3/4" floating bridge band, and a nylon-insert locknut to deliver a dependable, leak-resistant fit. They are specified by hose outer diameter (O.D.) — 2.75 inches nominal — so measure the outside of your hose before buying to ensure the correct fit.

How do these clamps create a reliable seal on hoses?

The T-bolt design provides even clamping force around the hose circumference, reducing pinch points and uneven compression that cause leaks. The floating bridge band distributes torque from the bolt to the band, yielding a consistent seal under torque and over time.

• Uniform pressure from T-bolt and bridge band
• 304 stainless resists rust and corrosion in wet environments
• Nylon-insert locknut helps maintain tension under vibration
• Range covers 2.56"–2.87" hose O.D. for 2.75" nominal hoses

What materials and parts make up the ROADFORMER clamp?

Each clamp is made from 304 stainless steel for the band and bridge, with a 1/4"-28 stainless bolt and a nylon-insert locknut. These materials balance strength and corrosion resistance for repeated use in automotive and industrial settings.

• 304 stainless band and floating bridge for durability
• 1/4"-28 stainless steel T-bolt for secure tightening
• Nylon-insert locknut to resist loosening from vibration
• Designed for longevity in harsh environments

How do I choose and install the correct clamp for my hose?

Confirm the hose outer diameter (O.D.), not the inner diameter (I.D.). Slide the clamp over the hose, position it over the fitting, and tighten the bolt with a wrench until the clamp compresses evenly. Avoid overtightening to prevent cutting into the hose material.

• Measure hose O.D.; this clamp fits 2.56"–2.87" O.D.
• Place clamp over the hose and align with fitting bead
• Tighten bolt evenly until a leak-proof seal forms
• Use hand tools or a wrench—do not use impact tools

Where are ROADFORMER T-bolt clamps typically used?

They are widely used in automotive cooling, turbo, and intake systems, heavy trucks, off-road equipment, industrial machinery, and agricultural applications where pressure, vibration, and exposure demand a robust clamp. The clamps are intended for external hose diameters within the specified range.

• Automotive: radiator, intercooler, and turbocharger hoses
• Industrial: pumps, compressed-air lines, and machine hoses
• Agricultural and off-road vehicles exposed to dirt and moisture
• Heavy-duty applications requiring durable, long-term seals

Who is this for: These ROADFORMER 2.75-inch T-bolt hose clamps are suited for mechanics, fleet operators, fabricators, and DIYers who need reliable, corrosion-resistant clamps for hoses with a 2.56"–2.87" outer diameter. If you require even clamping pressure under vibration and in wet or corrosive environments — and you measure hose O.D. before purchase — this 2-pack offers a durable solution built to industry-standard materials and construction.
