ROADFORMER 3.5" T-bolt hose clamp (95–103mm) is a heavy-duty 304 stainless steel clamp with a nylon-insert locknut designed to secure 3.5" nominal ID hoses with reliable, adjustable clamping force.

If you need a strong, corrosion-resistant clamp for automotive, marine, industrial or agricultural hoses, this 2-pack of ROADFORMER T-bolt clamps gives a wide tightening range (3.74"–4.06" / 95–103mm) and robust construction. Each clamp uses a 1/4"-28 300-series stainless bolt, a 3/4" 304 stainless band, a floating bridge, and a nylon insert locknut to maintain consistent torque and resist loosening under vibration.

How does this clamp handle different hose thicknesses and diameters?

The ROADFORMER clamp is sized for 3.5" nominal inside-diameter hoses and adjusts to fit outer diameters between 95mm and 103mm. Recommended hose wall thickness is about 3mm–6mm; very thin or very thick walls may fall outside the optimal gripping range. Always measure your hose outer diameter (O.D.) before buying to confirm fit.

  • Tightening range: 3.74"–4.06" (95mm–103mm)
  • Designed for hoses with 3mm–6mm wall thickness
  • Fits 3.5" nominal I.D. hose — check O.D. for accuracy

What materials and components give this clamp durability?

This clamp combines 304 stainless steel banding with a 300-series stainless bolt and a nylon-insert locknut to resist corrosion and retain torque. The floating bridge spreads compressive force evenly around the hose, reducing local deformation and improving long-term sealing performance in harsh environments.

  • 304 stainless steel 3/4" band for rust resistance
  • 1/4"-28 300-series stainless bolt for strength
  • Floating bridge to minimize hose pinching and concentrate clamping force evenly
  • Nylon-insert locknut to resist vibration loosening

How easy is it to install and reuse these T-bolt clamps?

Installation is straightforward: slide the clamp over the hose, position it where needed, and tighten the bolt with a wrench or hand tool until the desired compression is achieved. The robust construction allows these clamps to be removed and reinstalled when servicing lines, though re-tightening to proper torque is recommended each time.

  • Simple slide-on installation — no special tools required
  • Adjustable bolt and locknut allow re-tightening after maintenance
  • Designed for repeated service cycles with consistent clamp force

Who is this for? The ROADFORMER 3.5" T-bolt hose clamps suit mechanics, fleet operators, marine technicians, off-road enthusiasts, and maintenance crews who need durable, vibration-resistant clamps for coolant lines, intake systems, intercooler boots, fuel transfer lines, and assorted industrial hoses. They are a practical choice anytime a secure, stainless-steel clamp with a broad tightening range is required. Before ordering, confirm your hose O.D. and wall thickness to ensure a proper fit within the 95–103mm range.

FAQ

Q: Will this clamp fit a 3.5" hose?

A: Yes — it fits nominal 3.5" I.D. hoses with an outer diameter between 95mm and 103mm; confirm your hose O.D. before purchasing.

Q: Can I reuse the clamp after removal?

A: Yes — the stainless bolt and nylon locknut allow removal and reinstallation, but re-tighten to proper torque each time.
