Constructed from polyoxymethylene (POM), a rigid engineering thermoplastic, this fitting handles working pressures up to 300 psi and delivers reliable seals in pneumatic and fluid-handling lines. It accepts 1\/4 inch OD tubing on both ends. The single-piece union design allows fast field assembly and is well suited for tight spaces where wrench clearance is limited. HVAC technicians, plumbers, and industrial maintenance techs use this fitting in low-pressure pneumatic controls and fluid distribution systems.\u003c\/p\u003e\n\u003cp\u003eThis fitting is commonly installed in residential and light commercial HVAC control tubing, pneumatic signal lines, condensate management systems, and general-purpose fluid distribution runs. Its push-to-connect mechanism allows tubing to lock in on insertion and release with a simple collar press, reducing labor time on multi-connection assemblies. The tan POM body resists many common chemicals and lubricants encountered in trade service environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePush-to-connect design requires no tools, thread sealant, or soldering for assembly\u003c\/li\u003e\n  \u003cli\u003eRated to 300 psi working pressure\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch OD tube connection on both ends for inline union applications\u003c\/li\u003e\n  \u003cli\u003ePolyoxymethylene (POM) body offers high rigidity and chemical resistance\u003c\/li\u003e\n  \u003cli\u003eTan color for easy visual identification in multi-line installations\u003c\/li\u003e\n  \u003cli\u003eCompact, lightweight construction at 0.02 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style push-to-connect fitting for 1\/4 inch OD tubing in pneumatic control and fluid distribution applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by trade professionals including HVAC technicians and plumbers. Before servicing any pneumatic or fluid line, depressurize the system completely and isolate the supply. Ensure tubing ends are cut cleanly and squarely with a tubing cutter to achieve a proper seal on insertion. To disconnect, depress the release collar fully before pulling the tubing free to avoid damage to the internal collet.\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\u003eMaximum Working Pressure\u003c\/strong\u003e: 300 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Polyoxymethylene (POM)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Tan\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27121707\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: A4EU4-MG\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51540999864626,"sku":"A4EU4-MG","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/05acf79af2a188ccfe54dbe95b70f4c4_81c868be-49fb-43d2-8793-c41a83bd55c4.jpg?v=1785867179","url":"https:\/\/voomisupply.com\/products\/parker-a4eu4-mg-push-to-connect-union-1-4-in-od","provider":"Voomi Supply","version":"1.0","type":"link"}
