Vibrant Performance 19741 Straight Silicone Reducer Coupler, 3-1/2 in to 4 in Inlet/Outlet

The Vibrant Performance 19741 Tubing Coupler is a straight reducer designed to connect tubing with different inside diameters in automotive intake, intercooler, turbocharger, and custom fabrication applications. Its 3-1/2-inch inlet and 4-inch outlet provide a secure transition between tubing sizes while maintaining a clean, streamlined installation. The coupler is supplied individually in black silicone for a professional appearance and dependable service.
Constructed from durable silicone with a 0.200-inch-thick wall, this Vibrant Performance reducer coupler is built to handle demanding under-hood environments. The flexible material helps accommodate minor alignment differences during assembly, while the reinforced wall supports reliable connections where resistance to heat, pressure, and vibration is required. Its straight configuration is well suited for custom piping systems and performance-oriented plumbing installations.
Installation is straightforward when paired with properly sized tubing and suitable clamps. Slide the coupler fully onto each tube, position the connection for even engagement, and tighten the clamps securely for a dependable seal. The 4-1/2-inch overall length offers ample overlap for a stable connection without adding unnecessary bulk to the system. Use the Vibrant Performance 19741 when a durable, accurately sized silicone reducer is needed for a clean and reliable tubing transition.
