John Guest PM21128E - 12mm O/D x 8mm O/D Reducing Elbow

The John Guest PM21128E is a reducing elbow fitting designed for use in fluid handling systems. The fitting has a 12mm outside diameter (O/D) on one end and an 8mm O/D on the other end, allowing for the connection of tubing or piping with different sizes. The elbow shape of the fitting helps to redirect fluid flow at a 90-degree angle, which can be useful for navigating around obstacles or fitting into tight spaces.

This particular reducing elbow is colored red, which is a common color-coding convention used in fluid handling systems to indicate the type of fluid being transported. However, it's worth noting that color-coding conventions can vary between different industries and regions, so it's important to double-check the specific application requirements to ensure the correct fittings are being used.
