Molded from polypropylene, this fitting is rated for pressures up to 125 psi and a maximum working temperature of 212 degrees F, making it suitable for a wide range of fluid transfer applications. The single-barb design provides a secure grip on tubing without requiring additional tools, and the fitting meets FDA and NSF\/ANSI 51 standards for food-zone and potable-water-adjacent service. Plumbers, HVAC technicians, and pool service professionals install this fitting where a barbed-to-threaded transition is needed in low-pressure fluid lines.\u003c\/p\u003e\n\u003cp\u003eThis connector is commonly used in residential and light commercial plumbing, HVAC condensate drainage, water treatment, beverage dispensing, and pool and spa equipment where 1\/4-inch flexible tubing terminates at an NPT-threaded port. Its polypropylene construction resists corrosion and many common chemicals encountered in these trade applications. The black color provides easy visual identification during installation and inspection.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSingle-barb design secures 1\/4-inch ID tubing with 0.31-inch OD without clamps in low-pressure service\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch NPT male thread provides a standard threaded connection to ports and fittings\u003c\/li\u003e\n  \u003cli\u003ePolypropylene construction offers corrosion resistance and chemical compatibility for fluid transfer lines\u003c\/li\u003e\n  \u003cli\u003eRated to 125 psi maximum working pressure\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range of 0 degrees F to 212 degrees F\u003c\/li\u003e\n  \u003cli\u003eFDA Compliant and NSF\/ANSI 51 certified for food equipment and potable water contact applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with flexible tubing having a 1\/4-inch inside diameter and a 0.31-inch outside diameter, connecting to any standard 1\/4-inch NPT female-threaded port.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis fitting is installed by licensed plumbers, HVAC technicians, or qualified service professionals working on fluid transfer systems. Shut off fluid supply and depressurize the line before installation. Hand-thread the NPT connection until snug, then use a wrench for final tightening — avoid over-tightening polypropylene threads, as the material can crack under excessive torque. Push tubing firmly onto the barb until it seats fully against the fitting body, and confirm a leak-free connection before returning the system to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Male Connector\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Polypropylene\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Barbs\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBarb Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Inside Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 0.31 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4 inch NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 125 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Working Temperature\u003c\/strong\u003e: 0 degrees F (-12.20 degrees C)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 212 degrees F (100 degrees C)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.60 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: FDA Compliant, NSF\/ANSI 51\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PARKER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 325HB-4-4PP\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51539476316466,"sku":"325HB-4-4PP","price":18.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/507017cfe29a02e60845a4add06ee92d_bf8e260d-d558-477e-a4d5-20e2c2296d06.jpg?v=1785841068","url":"https:\/\/voomisupply.com\/products\/parker-325hb-4-4pp-barbed-tube-male-connector-1-4-in-npt","provider":"Voomi Supply","version":"1.0","type":"link"}
