ROADFORMER 6-inch T-Bolt Hose Clamp 158–166mm (6.22–6.54") 2-Pack — 304 Stainless, Wide 3/4" Band

ROADFORMER 6-inch T-bolt hose clamp (158–166 mm) is a heavy-duty 304 stainless steel clamp sold in a 2-pack for secure, even sealing on 6" nominal I.D. hoses.

These ROADFORMER clamps are built to fasten hoses used in turbo systems, intercoolers, radiators, coolant lines and other demanding connections. The band width, T-bolt hardware, floating bridge, and nylon locknut combine to deliver strong, uniform compression while protecting hose material from cuts and abrasion. Before buying, measure the hose O.D. to ensure it falls within the clamp's working range of 6.22" to 6.54" (158 mm–166 mm).

Will these clamps fit my 6-inch hose and thick-walled silicone couplers?

Yes—these clamps are specified for 6" nominal I.D. hoses with an operating range of 6.22"–6.54" (158–166 mm). They are designed to accommodate hose wall thicknesses typically around 3–6 mm (SAE standard), but you should confirm your hose O.D. before ordering.

• Working range: 158 mm–166 mm (6.22"–6.54")
• Designed for hoses with ~3–6 mm wall thickness
• Measure your hose outside diameter (O.D.) for accurate fit

How durable is the construction and will it resist corrosion?

These clamps use 304 stainless steel for the band and 300-series stainless hardware on the T-bolt, delivering strong corrosion resistance for automotive, marine, and outdoor use. The robust build reduces the chance of rust, galling, or premature failure in typical service environments.

• 304 stainless steel band resists rust and oxidation
• 300-series stainless T-bolt and hardware for long service life
• Floating bridge spreads load to prevent hose deformation

How do these clamps protect hoses and ensure a leak-free connection?

The clamp features a 3/4" wide band with smooth, rounded edges to minimize cutting or pinching of silicone and rubber hoses. The heavy-duty T-bolt provides even torque, while the floating bridge distributes pressure across the hose end to improve sealing and reduce stress points.

• Smooth, rounded band edges help prevent hose damage
• Wide band (3/4") increases contact area for better sealing
• Nylon-insert locknut maintains tension and resists loosening

How simple is installation and what tools will I need?

Installation is straightforward: slide the clamp over the hose, position it over the connection, and tighten with a wrench or socket. The clamp’s T-bolt head accepts common hand tools and the locking nut helps retain the chosen torque during operation.

• Fits over hose, position, then tighten with wrench or socket
• T-bolt head compatible with common hand tools
• Sold as a 2-pack for spares or paired connections

Who this is for: These ROADFORMER T-bolt hose clamps are intended for mechanics, performance tuners, fleet technicians, and DIYers who need reliable, corrosion-resistant clamps for turbocharging, intercoolers, radiator and coolant systems, marine fittings, off-road equipment, and agricultural machinery. If you require even clamping pressure, hose protection, and durable stainless hardware for 6" nominal hoses, these clamps provide a practical, professional-grade solution.
