ROADFORMER T-Bolt Hose Clamp 2.25 in (61–69mm) 2-Pack — 304 Stainless, 3/4 in Band, Nylon Locknut

This pair of ROADFORMER T-bolt clamps is built to deliver consistent clamping force for 2.25" nominal inside-diameter hoses, using a 3/4" 304 stainless band, a 300-series 1/4"-28 bolt, floating bridge and nylon-insert locknut for vibration resistance and repeatable performance. They suit a wide range of applications from automotive charge and coolant lines to industrial and marine hoses where a robust, corrosion-resistant clamp is required. Before ordering, confirm your hose inside diameter and wall thickness to ensure the clamp’s tightening range covers your hose O.D.

How do these T-bolt clamps secure a hose compared with worm gear clamps?

T-bolt clamps distribute compressive load over a wider band and use a bolt-and-bridge assembly that prevents channel cutting into thicker or reinforced hoses. They hold torque more reliably under pressure and thermal cycling, reducing the risk of leaks when properly sized.

• Wider 3/4" stainless band spreads clamping force evenly.
• Floating bridge prevents band deformation on high-pressure hoses.
• Nylon-insert locknut helps resist loosening from vibration.
• 304 stainless steel components for corrosion resistance.

What hose sizes and wall thicknesses work with this 61–69mm clamp?

ROADFORMER sizes these clamps for nominal 2.25" inside-diameter hoses; the effective tighten-up range is approximately 61mm to 69mm (2.40"–2.72") outer diameter when accounting for common hose wall thicknesses. The manufacturer recommends hose walls in the 3mm–6mm range for best sealing and fit.

• Designed for hose I.D. 2.25" nominal; check actual O.D. before purchase.
• Recommended hose wall thickness: 3–6mm (SAE standard guidance).
• Not suitable for hoses much thinner or thicker than recommended—inspect O.D.
• Range permits small adjustments to accommodate fittings or slight variation.

How easy is installation and reuse of these clamps?

Installation is straightforward with common hand tools: slide the clamp over the hose, position it over the barb or fitting, then tighten the 1/4"-28 bolt to the required torque. The assembly is serviceable and reusable, so you can remove and retighten clamps for maintenance without compromising the parts when handled properly.

• Install with a wrench or socket on the 1/4"-28 bolt.
• Floating bridge allows even tightening around irregular fittings.
• Nylon locknut reduces unintended back-off from vibration.
• Reusable stainless parts resist galling if lubricated lightly when reinstalled.

Which environments and systems are these clamps suited for?

These T-bolt clamps are intended for demanding settings where durability and steady clamping force matter. Typical uses include automotive intake and coolant systems, turbocharger plumbing, marine hoses, agricultural equipment, and industrial machinery lines where exposure to moisture, chemicals, and vibration occurs.

• Automotive: charge pipes, intercooler hoses, coolant lines.
• Marine and outdoor equipment: corrosion-resistant 304 stainless parts.
• Industrial and agricultural hoses exposed to vibration and pressure.
• Applications needing serviceable, heavy-duty clamping hardware.

Who is this for: Professionals and DIYers who need dependable, stainless-steel hose clamps sized for 2.25" nominal I.D. hoses and who value even clamp pressure, corrosion resistance, and reusability. Choose these ROADFORMER clamps if your hose outer diameter falls within the 61–69mm working range and your hose wall thickness meets the recommended 3–6mm guidance for reliable sealing under load.
