EVIL ENERGY 3.25" T-Bolt Hose Clamps for 3.27–3.58" OD Hoses — 304 Stainless, 19mm Band (4PCS)

These four EVIL ENERGY T-bolt clamps combine a wide 19 mm band, M6 hardware, and polished 304 stainless-steel construction to resist corrosion and maintain clamping force in demanding automotive and industrial environments. They are sized specifically for hoses with a 3.27–3.58 inch outer diameter and are designed for repeated use where a tight, even seal is essential—such as turbo intake boots, intercooler piping, radiator hoses, and large-diameter coolant lines.

How do these clamps create a strong seal on turbo or intercooler pipes?

The T-bolt design spreads pressure evenly across the hose band, producing a uniform squeeze that minimizes gaps or pinching. Rounded band edges reduce cut-through risk and preserve hose integrity under high boost or thermal cycling.

• Wide 0.75 in (19 mm) band for even clamping force
• M6×82 mm bolt for secure torque and repeatable tightening
• Rounded edges prevent hose damage and maintain seal

What materials and dimensions should I expect?

Each clamp is made from polished 304 stainless steel for corrosion resistance across salt, oil, water, and temperature extremes. The working range fits hose outer diameters from 83 mm to 91 mm (3.27–3.58 in), with band thickness of 0.6 mm.

• Material: 304 stainless steel, polished finish
• Working range: 83–91 mm (3.27–3.58 in)
• Band width: 19 mm (0.75 in); thickness: 0.6 mm
• Bolt size: M6×82 mm (3.23 in)

Are these clamps easy to install and reuse?

Yes—T-bolt clamps are straightforward to fit using a socket or wrench and can be retightened multiple times without losing clamping reliability. The simple hardware arrangement lets you set consistent torque values for repeatable performance during maintenance.

• Install with a 10 mm or appropriate socket/wrench on the M6 bolt
• Re-torqueable for service or hose replacement
• Rounded band edges simplify positioning and reduce slippage

Where are these most commonly used and what should I check before buying?

These clamps are ideal for turbo intake hoses, intercooler and radiator pipes, large coolant lines, and industrial hose couplings where a heavy-duty band clamp is required. Before ordering, measure the hose outer diameter to ensure it falls inside the 83–91 mm working range for a proper fit.

• Common uses: turbo boots, intercooler piping, coolant hoses, industrial lines
• Measure hose outer diameter, not inner diameter
• Order multiple clamps for long runs or paired connections

Who is this for? EVIL ENERGY 3.25" T-bolt clamps suit mechanics, performance enthusiasts, fleet maintenance teams, and fabricators who need durable, corrosion-resistant clamps for medium-large hoses. They are best when you want a reliable, serviceable clamp that resists rust and maintains even pressure across silicone or rubber connections in automotive, marine, and industrial settings.
