Molded from black polypropylene, this straight union fitting accepts tubing with a 1\/4 inch inside diameter and a 0.31 inch outside diameter on each end. It is rated for a maximum working pressure of 125 psi and a temperature range of 0 degrees F to 212 degrees F, making it suitable for a broad range of liquid transfer applications. The fitting meets FDA Compliant and NSF\/ANSI 51 standards, qualifying it for use in food-equipment and potable-water-adjacent systems.\u003c\/p\u003e\u003cp\u003eThis connector is used in residential and light commercial plumbing, HVAC condensate drain lines, water filtration systems, ice makers, and food-service equipment where a secure barb-to-barb union is needed without tools or fittings hardware. Polypropylene construction resists common cleaning chemicals and mild acids encountered in these environments. Licensed plumbers, HVAC technicians, and equipment service pros install this fitting wherever a quick, reliable tube splice is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSingle-barb design on both ends creates a secure push-to-connect tube union without additional hardware\u003c\/li\u003e\n\u003cli\u003ePolypropylene body resists corrosion, moisture, and common chemicals\u003c\/li\u003e\n\u003cli\u003eFDA Compliant and NSF\/ANSI 51 certified for food-equipment and potable-water-contact applications\u003c\/li\u003e\n\u003cli\u003eRated to 125 psi maximum working pressure\u003c\/li\u003e\n\u003cli\u003eWide temperature range: 0 degrees F to 212 degrees F (-12.2 degrees C to 100 degrees C)\u003c\/li\u003e\n\u003cli\u003eCompact overall length of 1.61 inches suits tight installation spaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for flexible tubing with a 1\/4 inch inside diameter and approximately 0.31 inch outside diameter.
