Flange Kit for Heater Boxes, With Hardware, Pair

EMPI Flange Kit for Heater Boxes & Exhaust (Pair)

Product Overview and VW Fitment

The EMPI 00-3640-0 flange kit is a crucial upgrade for air-cooled Volkswagen enthusiasts looking to eliminate exhaust leaks and create a professional, bolt-on connection. This kit includes two heavy-duty steel flanges designed to be welded onto your muffler or header, along with the necessary gaskets and hardware. It is specifically engineered for VW Type 1 engines, making it a perfect fit for the Volkswagen Beetle, Karmann Ghia, and air-cooled Dune Buggies or Sandrails. By converting a slip-fit or worn connection into a flanged union, you ensure a secure seal between your J-tubes or heater boxes and the rest of the exhaust system.

3 Pro Tech Tips for a Leak-Free Installation

Prep for Penetration: Before welding the steel flanges to your exhaust components, use a flap disc or wire wheel to grind the mating surfaces down to bare, shiny metal. Removing all paint, rust, and carbon buildup is essential for achieving a high-quality weld that won't crack or leak under the high vibration of a VW engine.

Clocking and Alignment: Never weld the flanges "blind." Bolt the flange to your J-tube or heater box with the gasket in place before you perform your tack welds. This ensures the bolt holes are perfectly aligned and the flange is seated at the correct angle. Once tacked, remove the hardware and gaskets to finish the final bead to avoid heat damage to the hardware.

Use Copper Anti-Seize: Air-cooled exhaust systems endure extreme heat cycles that often lead to frozen or snapped hardware. Apply a generous amount of high-temperature copper anti-seize to the threads of the included bolts during final assembly. This small step will save you hours of frustration the next time you need to remove your exhaust for engine service.
