Engineered from durable acetal plastic, it withstands pressures up to 150 psi and meets rigorous NSF/ANSI standards, making it ideal for potable water and industrial plumbing systems. ## Description This John Guest straight adapter fitting is made of acetal copolymer and has tube and NPTF male connectors. This straight adapter fitting is for connecting pipes or fittings with different end types, diameters, or materials in a straight line. It is a push-to-connect fitting that connects to pipes or tubing on one end and has a National Pipe Taper Fuel (NPTF) male connector on the other. The fitting 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. ## Features - Straight adapter connects pipes or fittings of different types in a straight line - Push-to-connect fitting connects to pipes or tubing on one end and has an NPTF male connector on the other - 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 | B005XTZJE0 | | Best Sellers Rank | #95,494 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #5 in Straight Tube Fittings | | Brand | John Guest | | Brand Name | John Guest | | Color | Gray | | Connector Type | Adapter | | Customer Reviews | 4.5 out of 5 stars 172 Reviews | | Exterior Finish | Brass | | Global Trade Identification Number | 00665626046414 | | Item Weight | 4.16 ounces | | Manufacturer | John Guest | | Manufacturer Part Number | PI011224S | | Material | Acetal | | Material Type | Acetal | | Model Number | PI011224S | | Number of Pieces | 10 | | Set Name | 10 | | Size | 3/8" Tube OD x 1/2" NPTF Male | | Thread Type | NPTF | | UPC | 665626046414 | | Unit Count | 10 Count | ## Images ![John Guest Acetal Copolymer Tube Fitting, Straight Adaptor, 3/8" Tube OD x 1/2" NPTF Male (Pack of 10) - Image 1](https://m.media-amazon.com/images/I/61embsf6ctL.jpg) ![John Guest Acetal Copolymer Tube Fitting, Straight Adaptor, 3/8" Tube OD x 1/2" NPTF Male (Pack of 10) - Image 2](https://m.media-amazon.com/images/I/61UDqbhuW-L.jpg) ## Available Options This product comes in different **Size** options. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/10543038-john-guest-acetal-copolymer-tube-fitting-straight-adaptor-3-8](https://www.desertcart.hr/products/10543038-john-guest-acetal-copolymer-tube-fitting-straight-adaptor-3-8) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-10-07*
