## Overview

The Yoebor Pneumatic Push to Connect Reducer Union Coupler (8mm x 4mm, 10pcs) is a high-performance plumbing fitting made from durable PBT polymer. Designed for quick, tool-free installation, it connects pipes of different diameters with a secure push-to-connect mechanism. Rated for pressures up to 150 psi and operating temperatures from 32 to 140°F, this coupler offers reliable resistance to solvents, heat, shrinkage, and impact—making it a trusted choice for professional pneumatic and fluid systems.

## Description

This reducing coupler fitting is made of polybutylene terephthalate (PBT) and has tube connectors. This reducing coupler has one end smaller than the other for connecting two pipes with different diameters. It is a push-to-connect fitting that connects to pipes or tubing on both ends. The fitting is made of polybutylene terephthalate (PBT), which is a polymer resistant to solvents, shrinkage, heat, and impact, and it can be treated to increase resistance to UV and flammability. The working pressure for this fitting is up to 150 pounds per square inch (psi), and its operating temperature ranges from 32 to 140 degrees F. Pipe fittings are components used for connecting, terminating, controlling flow, and changing the direction of piping in many different industries. Push-to-connect compression fittings do not require tools or sealants, and are useful in installations where a heat source, such as a soldering torch, is prohibited. When purchasing pipe fittings, consider the application, as this will affect material type, shape, size, and required durability. Fittings are available threaded or unthreaded, in many shapes, styles, sizes, and schedules (pipe wall thickness).
