PTP Wastegate Blanket for Tial MV-S 38mm Wastegate - Lava - FPRO35-159PTP Wastegate Blankets are designed to help minimize the heat soak transfer between the main body and actuator body of the wastegate. In doing so, we can help alleviate actuator diaphragm stress while in use, especially under extreme loads, due to extreme heat and dramatic temperature fluctuations. Results will be a more stable operation of the wastegate valve allowing consistent performance of the turbocharger. Another key benefit of the PTP
