A universal 50mm (2 in) weld-on flange for mounting a 50mm blow-off valve to aluminum charge piping. The saddle-cut base sits on the pipe for welding.

Fitment

  • Universal: for 50mm blow-off valves with a matching flange design
  • Weld-on: the flange is welded to your charge pipe

Check your valve's flange against the dimensions below before ordering. Not sure? Message us and we'll help.

Material / Finish

  • Aluminum, anodized silver finish

Dimensions (from the listing drawing)

  • Height: 36.0 mm (1.4 in)
  • Flange outer diameter: 58.7 mm (2.3 in)
  • Body outer diameter: about 51.2-51.6 mm (2.0 in)
  • Inner diameter: 47.2 mm (1.8 in)

What's included

  • 1 x 50mm weld-on BOV flange (valve, clamp and pipe not included)

Installation

Professional fabrication is required. This flange has to be welded to your charge pipe by a qualified fabricator, and because it is aluminum it should be welded to aluminum piping. Pressure-test the piping for leaks after welding.

Shipping time

This part ships from an overseas warehouse. Please allow about 3-6 weeks for delivery. Tracking details are shared once the order ships.

Returns

Returns are handled under our Refund Policy (linked in the store footer). Please check fitment before welding, cutting, or installing the part. Contact us before ordering if you have any fitment questions.

Good to know

This is a universal aftermarket part. It is not made for a specific vehicle, so the pipe size, flange and routing need to be checked against your setup before ordering.
