ROADFORMER T-Bolt Hose Clamp 2.5 in (2.31–2.64 in O.D.) 2-Pack — 304 Stainless, Nylon Locknut

ROADFORMER 2.5 inch T-bolt hose clamp (2-pack) is a heavy-duty, 304 stainless steel clamp sized for hoses with outer diameters from 2.31" to 2.64" and built for consistent, high-pressure connections.

These ROADFORMER clamps are made with a 304 stainless steel band, a 1/4"-28 stainless bolt, a floating bridge and a nylon-insert locknut to provide robust retention for turbo, intake, intercooler, radiator and coolant hose junctions. They are intended for applications that need even radial compression and corrosion resistance — from automotive and heavy trucks to off-road equipment and industrial uses. Before ordering, verify your hose outer diameter (O.D.) is within the specified 59mm–67mm range to ensure a proper fit.

How do these clamps deliver secure sealing on turbo and coolant hoses?

The T-bolt form produces uniform circumferential pressure, and the floating bridge spreads that force across the hose surface so clamp points aren’t concentrated in one spot. The 304 stainless band is smooth and rounded at the edges to reduce the risk of cutting or deforming rubber and silicone fittings. Combined, these design elements help maintain a steady mechanical hold under vibration and fluctuating pressure.

• Uniform compression via heavy-duty T-bolt mechanism
• Floating bridge reduces local stress and improves seal consistency
• Rounded 304 stainless band edges protect hose material
• Nylon-insert locknut reduces loosening under vibration

What size hose will this 2.5 inch clamp fit, and how should I measure?

The clamp’s working outside diameter (O.D.) range is 2.31"–2.64" (approximately 59mm–67mm). Measure the outer diameter of the hose where the clamp will sit, not the inside diameter (I.D.). If your measurement falls inside the stated range the clamp will close around the hose properly; if not, choose a different clamp size for correct tension and sealing.

• Working O.D. range: 2.31"–2.64" (59mm–67mm)
• Always measure hose outer diameter (O.D.), not I.D.
• Measure with hose installed on the fitting for accuracy
• Two clamps included — useful for opposing ends or spares

Are these clamps durable enough for heavy-duty and high-vibration environments?

ROADFORMER T-bolt clamps are engineered for long-term durability in demanding settings, featuring corrosion-resistant 304 stainless hardware and a locking nut to resist backlash. The combination of metal strength and vibration-resistant locknut makes them well suited to heavy trucks, industrial machinery and off-road use where loads and thermal cycles are common.

• 304 stainless steel band for corrosion resistance
• 1/4"-28 stainless bolt and nylon-lock nut to resist loosening
• Floating bridge minimizes localized fatigue on the hose
• Designed for repeated tightening and long service life

How easy is installation and what tools are required?

Installation is straightforward: slide the clamp over the hose, position it over the fitting, then tighten the bolt with a wrench or common hand tools until the desired clamp force is achieved. The product’s design accommodates easy placement and adjustment, and includes two identical clamps so you can install or keep a spare on hand.

• Slide clamp over hose, center on the connection, tighten bolt
• Wrench or socket for 1/4"-28 bolt is sufficient
• Two clamps in the package for dual connections or backup
• Rounded edges reduce risk of cutting while tightening

Who is this for: The ROADFORMER 2.5" T-bolt hose clamp (2-pack) is aimed at mechanics, fabricators and vehicle owners who install or service turbo, intercooler, radiator and coolant hoses and need a sturdy, corrosion-resistant clamp that holds under vibration and pressure. It suits professional fleets, off-road enthusiasts, agricultural and industrial equipment operators, and DIYers who require dependable clamping with easier installation and proven stainless-steel components. Remember to confirm your hose O.D. falls within 2.31"–2.64" (59mm–67mm) before purchase to ensure correct fitment.
