LWNWPPER 2.5 inch V-Band Clamp Kit with Male & Female Flanges, 304 Stainless, Weld-On

The LWNWPPER 2.5 inch V-Band Clamp kit is a stainless-steel exhaust coupling that includes a 2.5" male flange, a 2.5" female flange, and a V-band clamp to create a sealed, removable join for 2.5" OD pipes.

This kit is built from 304 stainless steel for corrosion resistance and is designed to join 2.5" outer-diameter pipes in exhaust, turbo, intercooler and ducting systems. It provides a reusable, strong connection that can be welded into pipe ends and then clamped for a tight seal that’s serviceable without cutting or re-welding. The set includes the male and female flanges sized for 2.5" inner openings plus the V-band clamp and mounting hardware.

How does this V-band clamp kit fit my 2.5" exhaust pipes?

The male and female flanges have inner diameters sized to accept a 2.5" OD pipe when welded to the pipe ends; the V-band clamp then gathers the two flanges to form the mechanical joint. Because the kit uses a V-shaped profile, it centers and compresses the flanges evenly for a reliable seal.

• Inner flange diameter: 2.5" to match 2.5" OD tubing.
• V-band clamp designed to wrap both flanges securely.
• Weld-on installation for permanent flange attachment.
• Reusable clamp allows disassembly for service or modification.

What materials and durability can I expect from the LWNWPPER set?

All components are made from 304 stainless steel to resist rust and most corrosive environments common to vehicle exhaust and industrial ducting. The metal thickness and clamp hardware are intended for long-term mechanical reuse without significant deformation.

• 304 stainless construction resists corrosion and water exposure.
• Heat-tolerant for exhaust and turbocharger applications.
• Robust screw and nut fasteners for repeated cycles.
• Built to withstand vibration and thermal expansion in typical systems.

How do I install the male and female flanges and use the clamp?

Installation is straightforward for someone comfortable with basic welding and metal prep. You polish and prepare the pipe ends, weld each corresponding flange to its pipe, then position the flanges together and tighten the V-band clamp to complete the joint.

• Step 1: Polish and clean pipe incision edges for welding.
• Step 2: Insert and weld male and female flanges at pipe ends.
• Step 3: Place V-band clamp over flanges and torque screws evenly.
• Provides a removable connection for maintenance without cutting.

Will this kit work for turbo, muffler or intercooler plumbing?

The kit is commonly used in exhaust and forced-induction plumbing where a serviceable, sealed connection is required. It suits turbo outlets, downpipes, muffler inlets, and intercooler or duct joints when the pipe OD matches 2.5" and heat/corrosion resistance is needed.

• Compatible with turbochargers, downpipes, and mufflers.
• Useful for pumps, diesel engine exhausts, and air ducts.
• Ideal where periodic disassembly is expected for tuning or repair.
• Not intended as a clamp for non-matching tube sizes without adapters.

Who is this for: The LWNWPPER 2.5 inch V-band Clamp with Male and Female Flanges is aimed at DIY mechanics, fabricators, and professional installers who need a durable, reusable coupling for 2.5" OD pipes. Choose this kit if you require a stainless solution for exhaust, turbo plumbing, or ductwork that can be welded in place and unclamped for service or upgrades.
