EVIL ENERGY 2.5" V-Band Clamp for 2.5 Inch Flanges — Stainless Steel, Cr-Mo M8 T-Bolt

EVIL ENERGY's 2.5 inch stainless steel V-band clamp is a heavy-duty, quick-release connector designed to join 2.5" flanges (flanges sold separately) with a reliable, even seal.

This V-band clamp is engineered for turbo, downpipe and exhaust applications where frequent disassembly, compact joints, and a tight seal are required. Built from corrosion-resistant stainless steel with a chromium-molybdenum M8 T-bolt, the clamp balances durability with straightforward installation. It does not include flanges; it is sized to fit EVIL ENERGY 2.5" flanges and other compatible 2.5" V-band flange sets.

How does this V-band clamp make exhaust and turbo connections easier?

The V-band design uses a single clamping point to compress a V-shaped bead on mating flanges, producing an even radial seal without multiple bolts. This simplifies removal and reassembly compared with multi-bolt flange joints and shortens service time during maintenance or upgrades.

• Single-bolt T-bolt operation for fast hand or tool tightening
• Even pressure distribution to reduce leaks
• Compact footprint ideal for tight engine bay locations

What materials and fastener specs ensure long-term performance?

The clamp body is stainless steel for corrosion resistance and high-temperature stability, while the T-bolt is chromium-molybdenum steel for strengthened clamping force. The fastener thread is M8 x 1.25 and the bolt length is 2.63 inches, giving sufficient engagement for reliable torque retention.

• Stainless steel clamp body resists rust and thermal cycling
• Cr-Mo T-bolt provides superior tensile strength
• M8*1.25 thread size and 2.63" bolt length for secure fitment

Which vehicle and exhaust parts work with this clamp?

This 2.5" V-band clamp is compatible with many aftermarket and performance systems that use 2.5" V-band flanges, including turbochargers, downpipes, mid-pipes and muffler interfaces. Because flanges are not included, you can pair the clamp with EVIL ENERGY or other 2.5" flange kits that share the same V-bead geometry.

• Commonly used on turbo housings and compressor outlets
• Suitable for downpipe, mid-pipe and muffler connections
• Works with aftermarket 2.5" V-band flanges (flanges not included)

How do I install and maintain the clamp for best results?

Installation requires placing the clamp over properly aligned flange halves with the V-bead seated in the clamp groove, then tightening the M8 T-bolt until the joint is snug and sealed. Inspect the clamp periodically for corrosion, bolt stretch or flange damage and re-torque after initial heat cycles.

• Hand-start the T-bolt, then torque incrementally for even compression
• Check after first heat cycle and re-tighten if necessary
• Replace clamp if bolt threads or band show wear or distortion

Who is this for: This EVIL ENERGY 2.5" V-band clamp suits DIY mechanics, professional tuners and fabricators who need a compact, serviceable coupling for turbo systems, exhaust assemblies and other 2.5" V-band flange joints. It's ideal when fast assembly/disassembly, strong clamping force, and corrosion resistance matter. Note: flanges are not included—purchase matching 2.5" V-band flanges if you don't already have them.
