EVIL ENERGY 4.0" V-Band Clamp with Male/Female Flanges — 304 Stainless, M8 T-Bolt Fastening

EVIL ENERGY's 4.0-inch V-band clamp with male/female flanges is a stainless-steel exhaust and turbo connection that delivers a fast, leak-resistant join without gaskets. This precision-made V-band assembly is designed to connect a 4.0" ID male pipe to a 4.0" OD female pipe quickly and reliably, making it ideal for turbocharger systems, downpipes, mufflers and custom exhaust work. The kit combines 304 stainless-steel flanges and band with a mild-steel M8*1.25 T-bolt for a secure, repeatable seal that resists corrosion and holds up under high temperatures.

How does this V-band clamp save time during installation and maintenance?

The V-band clamp's single-bolt action and male/female flange fit mean you can attach or separate sections in seconds, compared with multi-bolt flange systems. Its clamp design centers the flanges for fast alignment, cutting down shop time on swaps or servicing.

• One T-bolt secures the entire joint for rapid removal and reassembly.
• Male/female flange geometry aligns parts automatically; no extra gaskets needed.
• Ideal for frequent disassembly like turbo swaps or exhaust tuning.

Will this clamp create a reliable seal at high exhaust temperatures?

Yes — the 304 stainless-steel band and flanges offer good heat tolerance and corrosion resistance compared with mild steel, and the V-profile squeezes flanges evenly to minimize leaks. While not a gasketed joint, the male/female fit and uniform clamping pressure produce a consistent, tight seal under typical exhaust and turboheat loads.

• 304 stainless construction resists rust and oxidation at elevated temps.
• V-profile ensures even pressure distribution around the circumference.
• Designed for exhaust and turbocharger environments without added sealants.

What sizes and hardware are included, and will it fit my pipes?

This assembly is sized to join a 4.0" internal-diameter male pipe to a 4.0" outer-diameter female pipe. The T-bolt uses M8*1.25 threading. Confirm your pipe IDs/ODs match 4.0" measurements before ordering to ensure a correct fit.

• Fits 4.0" ID male to 4.0" OD female pipe interfaces.
• T-bolt fastener: M8*1.25 thread size for secure torqueing.
• Includes stainless band and flanges; mild-steel T-bolt included.

Can this V-band withstand motorsport or daily-driving use?

The combination of 304 stainless components and robust T-bolt fastening makes this clamp suitable for both high-performance and everyday exhaust systems. It's commonly used on turbochargers, downpipes and mufflers, provided the operating temperatures remain within stainless steel's typical performance range.

• Commonly used on turbo outlets, downpipes and muffler connections.
• Durable for street and many track applications; repeated removal possible.
• Not a gasketed splice — consider application-specific heat cycles and tuning demands.

Who is this for? This EVIL ENERGY 4.0" V-band clamp with male/female flanges is aimed at mechanics, fabricators and hobbyists who need a fast, serviceable, and corrosion-resistant way to join 4.0" exhaust or turbo tubing. Choose it if you value quick disassembly, precise flange alignment, and stainless-steel durability for performance or custom exhaust projects.

FAQ

Q: Does this V-band require a gasket?

A: No — the male/female flange design creates a tight seal without gaskets in typical exhaust and turbo installations.

Q: What material are the clamp and flanges made from?

A: The band and flanges are 304 stainless steel; the T-bolt is mild steel with M8*1.25 threads.
