Vibrant Performance Weld-On Fittings

Vibrant Performance weld-on fittings are for fabricators who build or modify exhaust, intake, fuel and boost plumbing. Nothing here is vehicle-specific, so you choose by thread, size and material instead of by truck.

The range includes thread-on sensor bung adapters for gauges and sensors, male AN titanium weld bungs, and tank weld bungs with a thread-on cap. Tank bungs are sold by outside diameter, so measure the hole you cut before you pick one.

Weld-on flange kits for blow-off valves are listed by valve style, with separate kits for Tial style, Greddy and HKS SSQ valves. Titles state whether the fitting is steel or mild steel and aluminum, which matters because the fitting must be weldable to the pipe it joins.

To choose, confirm three things: the fitting type you need, the pipe or tank size it will join, and the material. Titanium bungs suit titanium pipe, and steel suits steel.

Fitment is by dimension, so read each product page for sizes and thread. For other fittings and plumbing, see the full weld-on fittings range.
