5/32in (4mm) Male Straig ht One-Touch Fitting

The 5/32in (4mm) Male Straight One-Touch Fitting from Vibrant Performance is engineered for professionals and enthusiasts who demand reliability in pneumatic and fluid line connections. Whether you're building a custom air suspension system, routing compressed air for a turbo boost controller, or establishing a clean fuel line network in an engine bay, this fitting delivers the secure, leak-free performance that separates quality builds from amateur work. One-touch fittings have become the standard in modern vehicle modification because they eliminate guesswork and reduce installation time without sacrificing durability or safety.

This straight connector features a male thread design that accepts 5/32-inch (4mm) tubing with a simple push-and-lock mechanism—no tools, no wrenches, no stripped threads. The precision-engineered internal collet grips the tube securely under pressure while allowing quick disconnection when maintenance or reconfiguration becomes necessary. Vibrant Performance's manufacturing standards ensure consistent thread tolerances and seat geometry, critical for applications where vibration and temperature cycling would loosen inferior fittings. The compact 3.5 x 0.45 x 5.85-inch footprint makes this fitting ideal for tight engine compartments where space is precious and routing precision matters.

Mechanics and fabricators typically rely on this fitting for intake manifold vacuum systems, catch can breather lines, and secondary fuel line applications where flow rate doesn't demand larger diameter tubing. The straight configuration (as opposed to elbow or tee variants) works best in-line between components, offering minimal turbulence and easy splicing into existing pneumatic networks. At only 0.03 lbs, weight is negligible, making it suitable for weight-sensitive performance builds. This fitting pairs seamlessly with 1/4-inch and 5/32-inch tube stock and complements both stock and aftermarket engine management setups, making it an essential component for any serious automotive modification project.
