John Guest PI25810S - 1/4" O/D Tube x 5/16" I/D Hose Stem

The John Guest PI25810S is a fitting designed to connect a 1/4" outer diameter (O/D) tube to a 5/16" inner diameter (I/D) hose. The fitting is a stem type fitting, which means that it has a barbed end that is designed to securely hold onto the inside of the hose.

The fitting is made by John Guest, a manufacturer of high-quality fluid control products. It is commonly used in applications where a secure and reliable connection is required between a tube and a hose, such as in water filtration systems, refrigeration systems, and air conditioning systems.

To use the John Guest PI25810S fitting, simply insert the barbed end of the fitting into the end of the hose, making sure that the hose is securely attached to the fitting. Then, insert the other end of the fitting into the tube, again making sure that the tube is securely attached to the fitting. The result will be a tight and secure connection between the tube and the hose.
