Made from plastic construction, this plug installs without tools by inserting the tube end directly into the fitting body, which grips and seals in a single motion. Rated at 150 psi, it suits low-to-medium pressure lines where a secure, leak-free termination is required. HVAC technicians, plumbers, and industrial maintenance professionals use this fitting to terminate open tube ends during system modifications, testing, or equipment isolation.\u003c\/p\u003e\n\u003cp\u003eThis plug fitting is suited for residential and light commercial applications involving pneumatic controls, instrumentation tubing, or fluid distribution lines. Its push-to-connect design makes it a practical choice in tight spaces or during quick service calls where threading or soldering is not practical. The 1\/4-inch OD size is common in control-line and sensing-tube applications found in HVAC equipment, compressed air circuits, and water treatment systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePush-to-connect installation requires no tools or additional fittings\u003c\/li\u003e\n  \u003cli\u003eCaps 1\/4-inch OD tubing with a single insertion motion\u003c\/li\u003e\n  \u003cli\u003ePlastic construction suitable for low-to-medium pressure service\u003c\/li\u003e\n  \u003cli\u003eRated to 150 psi for reliable tube termination\u003c\/li\u003e\n  \u003cli\u003eCompact plug profile fits into confined plumbing and control-line spaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style push-to-connect plug for 1\/4-inch OD tubing in pneumatic, instrumentation, and fluid-handling systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eDepressurize and isolate the line fully before installing or removing any push-to-connect fitting. Confirm tubing OD measures exactly 1\/4 inch and that the tube end is cut cleanly and squarely with no burrs before insertion. Push-to-connect fittings rely on undamaged tubing surfaces for a proper seal — scored or oval tube ends will not seat correctly. Follow applicable system codes and the equipment manufacturer's service procedures when terminating active control or process lines.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Plastic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Pressure\u003c\/strong\u003e: 150 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27121707\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePSC Code\u003c\/strong\u003e: 4720\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: 639PLP-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51540980597042,"sku":"639PLP-4","price":27.36,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/886f62a1d1d1273608217676d7a42b0c.jpg?v=1785866918","url":"https:\/\/voomisupply.com\/products\/parker-639plp-4-push-to-connect-plug-1-4-inch-od","provider":"Voomi Supply","version":"1.0","type":"link"}
