EVIL ENERGY 2.5" T-Bolt Hose Clamps 304 Stainless Steel, 4-Pack — 63–71mm Heavy-Duty, Corrosion-Resistant

EVIL ENERGY 2.5 inch T-bolt hose clamps are heavy-duty 304 stainless steel clamps designed to secure 63–71 mm hoses with a durable, leak-resistant seal. These four T-bolt clamps combine robust materials and a flap design to give reliable, corrosion-resistant clamping for automotive, industrial, marine, and general-purpose hose connections. Finished in polished 304 stainless steel, each clamp balances strength with a smooth band edge to protect hoses while delivering high clamp force where you need it.

What size hoses do these clamps fit and how precise is the fit?

Each clamp is sized for an outside hose diameter range of 2.48–2.8 inches (63–71 mm), providing a tight fit across common silicone, rubber, and reinforced hoses. The extra band width helps distribute pressure evenly for a secure seal without cutting into the hose.

• Nominal clamp size: 2.5 in (63–71 mm working range)
• Band width: 0.75 in (19 mm) for even pressure distribution
• Band thickness: 0.6 mm (0.024 in) for strength and flexibility
• Bolt thread: M6 × 82 mm (3.23 in) for high clamp tension

How resistant are these clamps to corrosion and harsh conditions?

Made from 304 stainless steel, these T-bolt clamps resist rust and corrosion in wet, salty, and oily environments. The polished finish adds an extra layer of protection while helping the clamps maintain appearance and function over time under normal exposure.

• Material: 304 stainless steel for corrosion resistance
• Polished finish to reduce surface corrosion and wear
• Suitable for exposure to water, oil, and common industrial environments

How does the flap and band design protect hoses and improve sealing?

The clamps use a rounded-flap band design to prevent sharp edges from biting into hose material, lowering the risk of cuts and leaks. This design also helps the band conform to the hose surface, creating a more uniform compressive force for a reliable seal.

• Rounded edges reduce hose abrasion and tearing
• Flap design increases contact area for better sealing
• Sturdy T-bolt provides consistent, adjustable torque

What applications are these clamps best suited for?

These clamps are versatile for automotive coolant lines, turbo and intercooler hoses, marine plumbing, industrial equipment, and any application needing a high-strength hose connection. They perform well where vibration, pressure, or temperature swings require a more robust clamp than standard worm-gear types.

• Automotive: coolant, intake, and turbo hoses
• Marine: bilge, cooling, and fuel lines (with appropriate fittings)
• Industrial: pumps, compressors, and fluid transfer systems
• General repair: workshops, HVAC, and custom builds

Who is this for? If you need a dependable clamp that holds up to vibration, pressure, and corrosive environments, the EVIL ENERGY 2.5 inch T-bolt clamps are a practical choice. They suit mechanics, boat owners, fabricators, and maintenance professionals who want a durable stainless-steel solution with smooth edges to protect hose material. Before buying, confirm your hose outside diameter is between 63 and 71 mm to ensure a proper fit.

FAQ

Q: Will these clamps fit a 70 mm hose?

A: Yes. The working range is 63–71 mm, so a 70 mm outside diameter hose fits within the clamp range.

Q: Are these suitable for marine use?

A: Yes. Made from 304 stainless steel, they resist corrosion in marine environments under normal exposure.
