PPE 4.0" V-Band Flange - Exhaust Side (Female) 304 Stainless Steel (Universal)

This PPE 4.0" V-band flange is the exhaust-side (female) half of a V-band connection, built to mate with a matching male flange. It welds into custom 4.0" exhaust plumbing.

The flange is 304 stainless steel, so it resists the corrosion and high heat of exhaust service. Paired with its mating flange and a V-band clamp, it forms a serviceable, leak-tight joint that can be separated for teardown or component swaps.

It is a universal part for fabricators building 4.0" exhaust or turbo plumbing. This is the flange only – the V-band clamp and the male mating flange are sold separately – so confirm you have the matching pieces for your build before ordering.
