Molded from white nylon, this fitting accepts tubing with a 3\/4 inch inside diameter and a 0.8 inch outside diameter on each end. It handles working pressures up to 125 psi and operates across a temperature range of -40 degrees F to 200 degrees F. At 2.97 inches in overall length and weighing just 0.01 pounds, it is a compact, lightweight component suited for tight installation spaces. It meets FDA compliance and NSF\/ANSI 51 standards, making it appropriate for food-equipment and potable-water adjacent applications.\u003c\/p\u003e\n\u003cp\u003eThis union connector is used in plumbing, HVAC, and food-service equipment applications where a secure, leak-resistant barbed connection is required between two runs of compatible flexible tubing. The single-barb design provides a straightforward push-on installation and is commonly found in water treatment systems, ice machines, beverage dispensing equipment, and light-duty fluid transfer lines. Installation is typically performed by licensed plumbers or qualified equipment service technicians working on low-pressure fluid systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSingle-barb union design joins two 3\/4 inch ID flexible tube sections end to end\u003c\/li\u003e\n  \u003cli\u003eNylon construction resists corrosion and is compatible with a range of low-pressure fluids\u003c\/li\u003e\n  \u003cli\u003eRated to 125 psi maximum working pressure\u003c\/li\u003e\n  \u003cli\u003eWide temperature range: -40 degrees F to 200 degrees F (-40 degrees C to 93.3 degrees C)\u003c\/li\u003e\n  \u003cli\u003eFDA compliant and NSF\/ANSI 51 certified for food-equipment fluid contact applications\u003c\/li\u003e\n  \u003cli\u003eCompact at 2.97 inches overall length and weighing 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service fitting for flexible tubing systems with a 3\/4 inch inside diameter and 0.8 inch outside diameter.
