John Guest PI2586S - 1/4" O/D Tube x 3/16" I/D Hose Stem

The John Guest PI2586S is a fitting that allows a 1/4" outer diameter (O/D) tube to be connected to a 3/16" inner diameter (I/D) hose. The stem of the fitting is designed to be inserted into the hose, while the other end of the fitting is sized to accept a 1/4" O/D tube. This type of fitting is commonly used in applications where flexible tubing is required, such as in pneumatic and fluid control systems.

It's important to ensure that the fitting is the correct size for both the tube and the hose it will be connecting to, as using the wrong size fitting can result in leaks, poor performance, and even damage to the system. The John Guest brand is known for its quality and reliability, so this particular fitting should be a good choice for most applications.
