The Fitting 3/8in Tube to 3/8in Barb from DERALE is a precision hose adapter designed for automotive cooling and fluid transfer systems. This fitting is essential for those fabricating custom radiator bypass loops, upgrading coolant circulation, or integrating aftermarket transmission coolers. Mechanics and automotive enthusiasts depend on quality adapters like this to ensure secure and leak-free connections.
This adapter connects a 3/8-inch rigid tube to a 3/8-inch barbed hose inlet, facilitating seamless integration between hard plumbing and flexible hoses. The barb design provides a mechanical grip when the hose is fitted over the adapter, helping to prevent blowoff under pressure. This design minimizes the need for excessive hose clamps, which can restrict flow or damage tubing.
Ideal for modified cooling systems, custom water-cooling builds, and OEM component replacements, this fitting is suitable for street, racing, and off-road applications. Installation is straightforward—simply insert the barbed end into your 3/8-inch hose and secure it with a stainless steel hose clamp. This fitting is a must-have for anyone looking to custom-fabricate or modify engine cooling systems, transmission coolers, or oil cooler circuits.
