About this part

Product Details

Machined from 6061 aluminum alloy, this straight adapter fitting features a male 1/8" NPT thread on one end and a 3/16" barb on the other. The black anodized finish not only looks sharp but also helps protect the aluminum from corrosion. This fitting is designed to create a reliable, leak-free connection between components with NPT ports and flexible hoses.

You'll find these fittings commonly used when setting up fuel lines, oil lines, or vacuum systems. The barb end is sized to securely grip a 3/16" inner diameter hose, while the NPT threads are standard for many automotive components like oil pumps, fuel filters, and gauges. Its straightforward, straight design makes routing simple in tight engine bays.
