It accepts 1\/4 inch outside-diameter tubing and is constructed from Perfluoroalkoxy (PFA) and Polytetrafluoroethylene (PTFE) materials, making it chemically resistant and suitable for aggressive fluid and gas service environments. The plastic grip-type compression mechanism provides a secure, leak-resistant seal when properly seated. Plumbers, HVAC technicians, and industrial service technicians install this fitting in systems where chemical compatibility and corrosion resistance are required.\u003c\/p\u003e\n\u003cp\u003eThis compression union is well-suited for use in residential and light commercial plumbing, HVAC refrigerant or chemical feed lines, laboratory tubing systems, and any application where PFA or PTFE tubing is routed through a straight union connection. The fitting is sold individually and is sized for 1\/4 inch OD tubing, a common dimension in instrumentation, chemical dosing, and fluid transfer applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAccepts 1\/4 inch outside-diameter tubing for a precise compression fit\u003c\/li\u003e\n  \u003cli\u003ePFA and PTFE construction provides broad chemical resistance and low friction\u003c\/li\u003e\n  \u003cli\u003ePlastic grip-type compression mechanism — no soldering or threading required\u003c\/li\u003e\n  \u003cli\u003eStraight union configuration for in-line tubing connections\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.1 pounds, suitable for tight or weight-sensitive installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style compression union fitting compatible with 1\/4 inch OD PFA and PTFE tubing in fluid and gas transfer applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by plumbers, HVAC technicians, or instrumentation technicians. Before installing, shut off fluid or gas flow and relieve any system pressure. Insert tubing fully into both ends of the union and hand-tighten the compression nuts until snug, then verify a leak-free connection before returning the system to service. Follow all applicable IPC and local plumbing codes for the specific application.\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\u003eConnection Type\u003c\/strong\u003e: Compression\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Union\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Perfluoroalkoxy (PFA) and Polytetrafluoroethylene (PTFE)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrip Type\u003c\/strong\u003e: Plastic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: GTC-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51539555746098,"sku":"GTC-4","price":93.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5d23f649d32caee608af8f402be537ea_5b5e35d7-aa1c-42b5-a0b9-800fa94c9df9.jpg?v=1785843005","url":"https:\/\/voomisupply.com\/products\/parker-gtc-4-compression-tube-union-1-4-in-tube-od","provider":"Voomi Supply","version":"1.0","type":"link"}
