COMPATIBILITY & APPLICATIONS
Where to Use This Fitting
This John Guest acetal fixed elbow fitting is approved for potable water systems, reverse osmosis installations, refrigerator lines, and tap or toilet connections. The food-grade construction also makes it suitable for beverage dispensing, CO2 lines, pneumatic air systems, and vacuum applications. To disconnect, simply unlock the nut, push the collet toward the fitting body, and pull the tubing to release. The acetal material provides enhanced strength and heat resistance compared to standard polypropylene fittings, making it ideal for both residential and light commercial water filtration projects.
💧 Pro Tip: NPT thread sizes do not correspond to ruler measurements. A 1/4" NPT fitting actually measures 0.540 inches in diameter. Always verify your existing thread size with the reference chart above before ordering to ensure a proper fit.
