Vortech Silicone Coupling 4.00" x 3.00" Straight Sleeve - Black 7PS400-300
4.00-Inch Straight Silicone Coupler for Vortech Intake & Charge Piping
The Vortech Silicone Coupling (PN 7PS400-300) is a premium straight silicone sleeve engineered for secure, leak-free connections in supercharger intake and charge piping systems. With a 4.00-inch inside diameter and a 3.00-inch overall length, this coupler provides increased sealing surface for improved clamp retention in higher-boost or higher-vibration applications.
Constructed from reinforced silicone and finished in black, this coupling is designed to withstand elevated temperatures, boost pressure, and engine bay vibration common to forced-induction environments. When paired with quality clamps, it delivers a durable, reliable seal suitable for both intake and pressurized charge pipe locations.
Design & Application
This straight silicone sleeve is ideal for applications requiring a 4.00-inch hose connection with additional engagement length. The 3.00-inch profile offers extra overlap compared to shorter couplers, making it well-suited for high-boost setups or areas where additional clamping surface is preferred.
As with all forced-induction hose connections, proper clamp selection and correct installation are essential to ensure consistent performance under boost.
Construction Features
- Reinforced silicone construction for strength and durability
- Designed for supercharger intake and charge piping applications
