EVIL ENERGY 3-inch T-Bolt Hose Clamps 304 Stainless, 77–85mm Range, 4-Pack, Polished

EVIL ENERGY 3-inch T-bolt hose clamps are stainless steel, heavy-duty clamps sized to secure 3.03–3.35" (77–85 mm) silicone and coolant hoses with a strong, leak-resistant grip.

These T-bolt clamps are built from 304 stainless steel and polished for corrosion resistance, making them suitable for turbo intakes, intercooler pipes, radiator lines and other high-vibration hose connections. The band has rounded edges to protect hoses from abrasion while the M6 bolt provides consistent clamping torque. Sold as a set of four, they replace worn factory clamps and provide a professional, secure seal for both street and off-road applications.

How do these clamps hold up under heat, salt, and road conditions?

The clamps use 304 stainless steel for the band, bolt and housing, which offers broad resistance to rust, salt spray and mild chemical exposure. The polished finish reduces surface corrosion and helps the clamps retain strength over time in coastal or winter climates.

• Material: 304 stainless steel components resist rust and corrosion.
• Finish: Polished surface limits oxidation and eases cleaning.
• Durability: Designed for repeated tightening without losing grip.

Are these clamps the right size for my 3" silicone hose?

Measure your hose's outside diameter before buying — these clamps reliably fit hoses with an outside diameter from 3.03" to 3.35" (77–85 mm). Their 0.75" (19 mm) wide band spreads load to minimize hose distortion and improve sealing against air or fluid leaks.

• Working range: 3.03–3.35 in (77–85 mm) outside diameter.
• Band width: 0.75 in (19 mm) for even pressure distribution.
• Bolt size: M6×82 mm (3.23 in) for strong, adjustable torque.

How do these clamps protect the hose and prevent leaks?

The clamps feature a flap-style band with rounded edges so there are no sharp corners to cut into silicone or rubber hoses. The T-bolt design produces uniform compression along the band, making a more consistent seal than standard worm-drive clamps.

• Rounded band edges prevent abrasion and hose cutting.
• T-bolt assembly delivers even radial pressure for a tight seal.
• Sturdy bolt thread maintains clamping force under vibration.

What applications are these clamps best suited for?

These clamps are useful across automotive, industrial and marine settings wherever medium-diameter hoses need a secure connection. Typical uses include turbo intake couplers, intercooler and radiator hoses, coolant lines, and other oil or air hose joints.

• Automotive: turbo plumbing, intercoolers, radiator and coolant hoses.
• Industrial: fluid transfer lines and air hoses subject to vibration.
• Marine and outdoor: corrosion-resistant fit for coastal conditions.

Who this is for: If you maintain performance engines, retrofit intercooler or turbo piping, run heavy-duty HVAC or fluid systems, or need corrosion-resistant hose clamps for outdoor equipment, these EVIL ENERGY T-bolt clamps offer a strong, long-lasting fastening option. They suit mechanics, tuners, fleet technicians and DIY enthusiasts who want a reliable replacement for weak factory clamps. Before ordering, confirm your hose outside diameter is within the 77–85 mm range to ensure a proper fit.
