Tnisesm 16Pcs 8 Sizes T-Bolt Hose Clamps

Tnisesm 16-piece T-bolt hose clamp assortment is a heavy-duty 304 stainless steel kit that secures hoses from 28 to 91mm (1–3") with rolled edges and polished finishes for lasting, damage-free connections.

Whether you’re tightening turbo intake couplers, replacing radiator clamps, or prepping an intercooler install, this kit gives you a range of T-bolt clamps engineered for strength and corrosion resistance. The set contains eight size ranges with two clamps each, so you have the right fit for common automotive and industrial hoses. The clamps are built from 304 stainless steel and finished to avoid sharp edges, helping protect softer hoses while delivering reliable clamping torque.

What sizes are included and how do they cover common hose IDs?

The set includes eight distinct diameter ranges sized to fit hose inner diameters from about 28mm to 91mm (roughly 1" to 3"). Each size comes with two clamps so you can handle multiple connections or keep a spare on hand. These ranges cover small vacuum and coolant hoses up through larger intercooler and turbo couplers.

• 0.75" (28–34mm)
• 1.00" (32–37mm)
• 1.25" (36–44mm)
• 1.5" (44–52mm)
• 1.75" (50–57mm)
• 2.00" (56–64mm)
• 2.5" (70–78mm)
• 3.00" (83–91mm)

How durable and corrosion-resistant are these clamps for under-hood use?

Each clamp is stamped and formed from 304 stainless steel, a commonly used grade for corrosion resistance in automotive environments. The metal resists rust and holds up under heat cycles typically found around radiators and turbo systems. A polished finish reduces surface imperfections that can accelerate corrosion or cut into hoses.

• 304 stainless construction for long-term rust resistance
• Polished finish that minimizes rough edges and wear
• Built to withstand high-temperature engine bay exposure

Will the clamps protect my hoses from being pinched or cut?

These T-bolt clamps use a rolled edge design that creates a smoother contact surface against the hose. That prevents the clamp band from digging into soft rubber or silicone, extending hose life and reducing leak risk. The assembly is also finished smoothly to avoid burrs or sharp spots.

• Rolled edge band guards hose material from abrasion
• Even clamping pressure from the T-bolt reduces localized stress
• Fine finishing process eliminates rough metal burrs

How easy are the clamps to install and reuse?

T-bolt clamps are designed for mechanical strength and straightforward installation: loosen the bolt to fit over the hose, then tighten uniformly for a secure seal. The robust bolt-and-nut fastener permits re-tightening and reuse when performing maintenance or swapping components. Their design provides a repeatable clamping force without deforming the band when used within the specified range.

• Simple bolt tightening with standard sockets or wrenches
• Reusable hardware for routine maintenance
• Consistent clamping torque across the band for reliable seals

Who this kit is for: mechanics, DIY tuners, fleet technicians, and anyone working on cooling systems, turbo intakes, intercoolers, or flexible hose connections will find this Tnisesm assortment useful. It’s suited for projects that require durable, corrosion-resistant clamps with hose-friendly edges and a range of sizes to cover common 1–3" hose IDs. Keep the kit in a garage toolbox or service van to ensure the right clamp is available when you need it.
