Designed for quick, tool-free connections between pipes of different diameters, it withstands pressures up to 150 psi and temperatures from 32 to 140°F. Ideal for professional and DIY use, this 10-piece set offers reliable, solvent- and impact-resistant performance in a compact, easy-to-install design. ## 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). ## Features - Reducing coupler for connecting two pipes with different diameters - Push-to-connect fitting connects to pipes or tubing on both ends - Made of polybutylene terephthalate (PBT) for resistance to solvents, shrinkage, heat, and impact - Working pressure of up to 150 psi - Operating temperature ranges from 32 to 140 degrees F ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07CG7GQBK | | Best Sellers Rank | #76,167 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #252 in Push-to-Connect Fittings | | Brand Name | Yoebor | | Color | Metric Tube | | Connector Type | Union | | Customer Reviews | 4.7 4.7 out of 5 stars (159) | | Exterior Finish | Brass | | Item Dimensions | 1.34 x 0.6 x 0.6 inches | | Manufacturer | Metalwork | | Material Type | Plastic | | Number of Pieces | 10 | | Set Name | Yoebor Pneumatic Push to Connect Reducer Union Coupler 8mm x 4mm OD 10pcs | | Size | 8mm x 4mm | | Thread Type | NPT | | Unit Count | 10 Count | ## Product Details - **Brand:** Yoebor - **Color:** Metric Tube - **Connector Type:** Union - **Exterior Finish:** Brass - **Item dimensions L x W x H:** 1.34 x 0.6 x 0.6 inches - **Manufacturer:** Metalwork - **Material:** Plastic - **Number of Pieces:** 10 - **Size:** 8mm x 4mm - **Thread Type:** NPT ## Images ![Yoebor Pneumatic Push to Connect Reducer Union Coupler 8mm x 4mm OD 10pcs - Image 1](https://m.media-amazon.com/images/I/61b8aWUsV5L.jpg) ![Yoebor Pneumatic Push to Connect Reducer Union Coupler 8mm x 4mm OD 10pcs - Image 2](https://m.media-amazon.com/images/I/51sy8lulV8L.jpg) ![Yoebor Pneumatic Push to Connect Reducer Union Coupler 8mm x 4mm OD 10pcs - Image 3](https://m.media-amazon.com/images/I/41mvtIwA5xL.jpg) ![Yoebor Pneumatic Push to Connect Reducer Union Coupler 8mm x 4mm OD 10pcs - Image 4](https://m.media-amazon.com/images/I/31H6sbpdqPL.jpg) ![Yoebor Pneumatic Push to Connect Reducer Union Coupler 8mm x 4mm OD 10pcs - Image 5](https://m.media-amazon.com/images/I/41uCIH19L5L.jpg) ## Available Options This product comes in different **Color, Size, Number Of Items** options. ## Questions & Answers **Q: what does the "OD" stand for?** A: "OD" stands for Outside Diameter of the tubing. **Q: Can this be used for water filtration system?** A: Yes.
