EVIL ENERGY 3.5" V-Band Clamp with Male/Female Flanges — 304 Stainless, T-Bolt for Exhaust/Turbo

EVIL ENERGY's 3.5-inch V-band clamp with male/female flanges is a stainless-steel coupling that quickly and securely joins 3.5" ID to 3.5" OD pipes for exhaust, turbo, and downpipe connections.

Designed for high-temperature automotive and industrial exhaust systems, this V-band assembly combines a 3.5" V-band clamp, matched male and female flanges, and a heavy-duty T-bolt to deliver even sealing pressure and fast serviceability. The kit uses 304 stainless steel for the clamping ring and flanges with a mild-steel M8*1.25 T-bolt, offering corrosion resistance and durability for repeated installations and removals where alignment and leak control matter.

How does this V-band clamp make installation faster?

The V-band design secures the flanges with a single-bolt action that compresses evenly around the joint, letting you connect or disconnect components in seconds versus multi-bolt flanges. Because the male and female flanges self-locate inside the band, alignment is simpler and you avoid fussy repositioning during assembly.

• Single T-bolt tightening for rapid connect/disconnect
• Self-aligning male/female flanges remove the need for gaskets
• Even circumferential pressure reduces retightening
• Ideal where frequent servicing or swaps are expected

What materials and sizes should I expect for longevity?

The clamp body and mating flanges are made of 304 stainless steel to resist oxidation and stand up to elevated exhaust temperatures. The included T-bolt uses mild steel with M8*1.25 threading to provide strong clamping force; this size matches the 3.5" ID-to-OD flange interface for a secure fit.

• 3.5" nominal inner diameter flange to 3.5" outer diameter pipe compatibility
• 304 stainless steel ring and flanges for corrosion and heat resistance
• M8*1.25 T-bolt for reliable torque and clamp hold
• Construction suitable for repeated assembly without gasket wear

Will this V-band clamp seal reliably without gaskets?

Yes — the male/female flange geometry is designed to produce a tight mechanical seal when compressed by the V-band, eliminating the need for a separate gasket in many applications. This reduces parts and simplifies fitment while maintaining alignment to prevent leaks from poor seating.

• Flange mating surfaces designed for dry-seal compression
• Even pressure distribution from the V-band minimizes leak paths
• Gasket-free setup reduces maintenance items and cost
• Suitable for exhaust, turbo and muffler joins where a metal-to-metal seal is acceptable

What sorts of systems and vehicles is this clamp compatible with?

The 3.5" V-band assembly is commonly used on performance and replacement exhaust systems, turbocharger outlets, downpipes, and muffler interfaces on cars, trucks, and custom builds. Its sizing and material set make it a versatile choice for both OEM-style repairs and aftermarket performance parts.

• Turbocharger outlets and compressor housing joins
• Downpipe and mid-pipe exhaust connections
• Muffler inlet/outlet couplings and removable sections
• Custom fabricated exhaust systems and motorsport applications

Who is this for? Installers, fabricators, and vehicle owners who need a fast, repeatable, and robust method to join 3.5" exhaust components will benefit most. If you want a corrosion-resistant clamp that simplifies alignment, reduces gasket dependency, and allows frequent disassembly for maintenance or tuning, the EVIL ENERGY 3.5" V-band with male/female flanges is built for that purpose.
