🛠️ Compound Turbo Dual Seal Connector Kit – High-Pressure Flexible Connection for Compound Turbocharged Systems
Engineered alongside the performance diesel experts at Stainless Diesel, this Compound Turbo Dual Seal Connector Kit delivers unmatched reliability and flexibility for compound turbo setups. Designed to eliminate the need for traditional silicone couplers and V-band clamps, this innovative solution uses a dual-seal design that holds tight under extreme boost pressure while allowing for movement and deflection—ideal for race-ready builds and high-horsepower street trucks.
