TiAL Wastegate Valve Seats

These TiAL® replacement wastegate valve seats are CNC machined from Nitronic 60 Stainless Steel for high temperature operation and great resistance to galling. Replacement valve seats are available for the 35mm, 38mm, MVS, F38, F41, V44, MVR, F46, and V60. Please note that TiAL's two 38mm valves, F38 and MVS, utilize a different valve seat and diaphragm. The valve seat for the V44 and MVR is the same.
