It accommodates a 1\/8 inch OD tube on one port and a 1\/4 inch OD tube on the other, making it suitable for reducing or transitioning between two tube sizes in a single inline connection. Constructed from nylon, the fitting is rated for up to 290 psi and is well suited for pneumatic control lines, instrumentation tubing, and low-pressure fluid transfer applications. HVAC technicians, plumbers, and controls technicians routinely use push-to-connect fittings of this type where quick, reliable tube connections are required in tight spaces.\u003c\/p\u003e\n\u003cp\u003eThis fitting is used in residential and light commercial pneumatic and fluid control systems where different tube sizes must be joined inline. Common install scenarios include control line runs on HVAC equipment, compressed air distribution, and instrumentation circuits. The push-to-connect design allows the tube to be inserted and locked in a single motion, reducing assembly time compared to compression or barbed alternatives. The nylon body resists common chemicals and moisture encountered in mechanical room and equipment cabinet environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePush-to-connect design allows tool-free tube insertion and secure locking\u003c\/li\u003e\n  \u003cli\u003eReduces or transitions between 1\/8 inch OD and 1\/4 inch OD tube sizes in a single fitting\u003c\/li\u003e\n  \u003cli\u003eNylon construction provides chemical and moisture resistance\u003c\/li\u003e\n  \u003cli\u003eRated to 290 psi for use in pneumatic and low-pressure fluid applications\u003c\/li\u003e\n  \u003cli\u003eCompact inline profile fits tight equipment cabinets and control panels\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style push-to-connect replacement for pneumatic and fluid control tubing applications using 1\/8 inch OD and 1\/4 inch OD tubing.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by HVAC technicians or controls technicians. Before servicing any pneumatic or fluid line, depressurize the circuit completely and confirm zero pressure with a gauge before disconnecting existing fittings. Ensure tube ends are cut cleanly and squarely with a tubing cutter for a proper seal. Do not exceed the 290 psi pressure rating of the fitting.\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\/8 x 1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Nylon\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 290 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Push-To-Connect\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConfiguration\u003c\/strong\u003e: Union (Tube x Tube)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: LEGRIS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3104 56 53\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LEGRIS","offers":[{"title":"Default Title","offer_id":51747527196978,"sku":"3104 56 53","price":22.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/88afd5aa25b0427094b3137de171d2c3.jpg?v=1788881938","url":"https:\/\/voomisupply.com\/products\/legris-3104-56-53-push-to-connect-union-tube-fitting","provider":"Voomi Supply","version":"1.0","type":"link"}
