FAQ
Is CPP 132681 compatible with all S400 variants?
It’s designed for standard S400 CHRA-to-turbine housing V-band interfaces (S400SX/SX3, common S46x/S47x/S48x builds). If you’re running a non-standard or custom housing, contact us.
Will this clamp fix an exhaust leak?
It will secure a proper seal, but leaks caused by warped flanges, damaged seats, or poor alignment require inspection and repair before clamping.
What torque should I use?
Tighten evenly in small increments around the band. Final torque depends on hardware and lubricant; avoid over-torquing. If unsure, reach out and we’ll advise for your setup.
Do I need a new gasket?
The S400 CHRA-to-turbine joint is a metal-to-metal V-band interface. Ensure clean, flat mating surfaces; gaskets are typically not used at this joint.
