Product Description

Custom intake and intercooler piping often needs a simple, reliable coupler to join two sections of same-diameter tubing - and a coupler that's too short, too thin-walled, or rated for lower temperatures than the application demands is a common point of failure. The Vibrant 27395 addresses that with a full 12" length at 3.75" ID, giving fabricators plenty of overlap for a secure clamped connection.

Built from hand-wrapped, 4-ply reinforced silicone rather than basic single-layer rubber, it's rated across an unusually wide -65°F to 500°F range and holds its shape under sustained pressure without swelling or cracking. It's a straightforward, high-durability building block for custom intake, intercooler, or coolant plumbing where a long, large-diameter straight connection is exactly what the layout calls for.
