Fragola 3/16in x 1/8 NPT Brass Compression Fitting

Fragola is known for making solid plumbing and fitting components for performance vehicles. This brass compression fitting is a good example, designed to connect a 3/16-inch line to a 1/8 NPT threaded port. It’s a straightforward part, but using well-made fittings like this is key to preventing leaks in your fuel, oil, or vacuum lines.

The fitting is made from brass, which is a durable material that holds up well in most automotive environments and resists corrosion. The compression style means you simply slide your 3/16-inch tubing into one end and tighten the nut, creating a seal against the fitting body. The other end has the standard 1/8 NPT male threads, which are common for sensors, gauges, or adapters in many engine bay setups. It’s a simple, effective way to adapt different line sizes and thread types.
