Buying Guide: 1/4 NPT to 3/8 Barb

Understanding the Basics

When I first started looking for a 1/4 NPT to 3/8 barb fitting, I quickly realized the importance of understanding what these terms mean. The NPT (National Pipe Thread) refers to the standard for tapered threads used on pipes, while the barb is a fitting that allows for the connection of hoses.
