This union elbow fitting joins two tubes at an angle to change the direction of flow between the pipes. It is a push-to-connect fitting that accepts the insertion of nylon, soft nylon and polyurethane tube fittings. It is made of acetal copolymer plastic, which has low moisture absorption, high tensile and flexural strength, and is hard and fatigue resistant. The working pressure for this fitting is up to 150 pounds per square inch (psi). This fitting meets National Sanitation Foundation (NSF)/American National Standards Institute (ANSI) standards 14, 51, and 61 for plastic piping systems, food equipment materials, and use with drinking (potable) water.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).John Guest manufactures push-to-connect fittings and pipe and plastic plumbing systems. The company, founded in 1961, is headquartered in Great Britain and meets International Organization for Standardization (ISO) standard 9001. Review: good parts so far - The price is about average though I do like the free shipping. They work great for my RO. Review: Get the best with John Guest! - I have installed six reverse osmosis water filtration systems with numerous connections, and I have never had a leak with a John Guest product, so I'll keep buying them as long as they keep making them. Also, I use the red John Guest brand locking clips at every tubing connection, so that might be the secret to my "no leak" success record. Press-to-connect is the way to go! ## Features - Union elbow for joining two tubes at an angle - Accepts nylon and polyurethane tube fittings - Made of acetal copolymer plastic for low moisture absorption and high tensile and flexural strength - Working pressure of up to 150 psi - Meets NSF/ANSI standards 14, 51, and 61 for quality assurance ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B005XTQC1Y | | Best Sellers Rank | #67,750 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #247 in Push-to-Connect Fittings | | Brand | John Guest | | Brand Name | John Guest | | Color | White | | Connector Type | Elbow , Union | | Customer Reviews | 4.6 out of 5 stars 119 Reviews | | Global Trade Identification Number | 00665626060366 | | Item Dimensions | 5.2 x 3 x 0.6 inches | | Item Weight | 0.05 Pounds | | Item dimensions L x W x H | 5.2 x 3 x 0.6 inches | | Manufacturer | John Guest | | Manufacturer Part Number | PM0308S | | Material | Acetal | | Material Type | Acetal | | Model Number | PM0308S | | Number of Pieces | 10 | | Set Name | Pack of 10 | | Size | 5/16" Tube OD | | Thread Type | NPT | | UPC | 665626060366 | | Unit Count | 10 Count | ## Product Details - **Size:** 5/16" Tube OD - **Material:** Acetal - **Brand:** John Guest - **Color:** White - **Item dimensions L x W x H:** 5.2 x 3 x 0.6 inches - **Connector Type:** Elbow, Union - **Thread Type:** NPT - **Item Weight:** 0.05 Pounds - **Number of Pieces:** 10 - **Global Trade Identification Number:** 00665626060366 ## Images ![John Guest Acetal Copolymer Tube Fitting, Union Elbow, 5/16" Tube OD (Pack of 10) - Image 1](https://m.media-amazon.com/images/I/71g9Lp3MlJL.jpg) ![John Guest Acetal Copolymer Tube Fitting, Union Elbow, 5/16" Tube OD (Pack of 10) - Image 2](https://m.media-amazon.com/images/I/610s7RQkseL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ good parts so far *by M***S on July 8, 2025* The price is about average though I do like the free shipping.
