EVIL ENERGY T-Bolt Hose Clamps 71–78mm (2.75") 4-Pack — 304 Stainless, 19mm Wide Heavy-Duty

EVIL ENERGY 2.75" T-bolt hose clamps are heavy-duty stainless steel clamps sized for 71–78mm (2.8–3.07") hose outer diameters, delivering a secure, corrosion-resistant seal for turbo, intercooler, and coolant hose connections.

These T-bolt clamps are engineered for demanding automotive and industrial use where a reliable, vibration-resistant clamp is required. Made from 304 stainless steel and finished with polished edges, the clamps resist rust and chemical exposure while protecting hose material from cuts. Each clamp spans a 71–78mm adjustable range (2.8–3.07"), has a 19mm width and a 0.6mm thickness, and uses an M6×82mm bolt for strong, uniform tightening.

How do these clamps improve hose sealing compared with worm-drive clamps?

T-bolt clamps provide a broader, stiffer band that distributes clamping force evenly around the hose, reducing localized compression and the chance of leaks under boost or pressure. The integrated T-bolt and nut assembly yields higher clamp torque and less slippage.

• Wider 19mm band spreads load across hose for better sealing.
• Stainless 304 resists corrosion in wet or salty environments.
• M6 bolt enables higher torque without band deformation.

Will these fit my hose or pipe—what exact sizes do they cover?

Measure the outside diameter (OD) of the hose to confirm fit. These clamps cover hoses with a 71–78mm (2.8–3.07") OD; they are optimized for 2.75" (approximate) hose IDs when paired with typical silicone wall thicknesses.

• Adjustable working range: 71mm–78mm (2.8–3.07").
• Band width: 19mm; band thickness: 0.6mm for strength.
• Bolt thread: M6×82mm for deep, secure engagement.

What materials and design details help them last in harsh conditions?

Constructed from high-quality 304 stainless steel, the clamps resist salt spray, oil, coolant, and temperature swings. Rounded band edges reduce the risk of cutting hoses and improve long-term sealing by preventing abrasive wear.

• 304 stainless resists rust, corrosion, and chemical exposure.
• Polished, rounded edges protect hose integrity and lower abrasion.
• Robust T-bolt and nut resist vibration loosening under load.

Where are these clamps typically used and how do I choose quantity?

They’re ideal for turbo intake, intercooler piping, radiator and coolant hoses, and other pressurized or high-vibration hose joints in cars, trucks, and industrial equipment. A four-pack gives spare parts for multiple connections or quick replacement during maintenance.

• Common uses: turbo/charger piping, intercooler hoses, coolant lines.
• Four clamps per pack—enough for kits or to keep spares on hand.
• Great for professional shops and DIY maintenance alike.

Who is this for: These EVIL ENERGY T-bolt clamps suit mechanics, tuners, fleet maintenance teams, and experienced DIYers who need a durable, precise clamp for pressurized or high-heat hose connections. Choose them when corrosion resistance, high clamping torque, and hose protection are priorities—especially for turbo and intercooler plumbing where reliable seals under boost matter.
