With a 1\/4 inch outside diameter tube size and a maximum working pressure of 225 psi, this black fitting handles the demands of compressed air distribution in industrial and shop environments. The push-to-connect design allows a technician to seat tubing with a single push and release it by depressing the collet ring, reducing connection time and eliminating the need for thread sealing compounds on the tube joint. It is a compact, inline union used to join two runs of same-size tubing end to end.\u003c\/p\u003e\n\u003cp\u003eThis fitting is suited for use in compressed air systems where fast, reliable inline connections are needed. Typical applications include pneumatic control lines, tool-drop hose assemblies, and branch distribution plumbing in manufacturing, maintenance, and assembly environments. The rated temperature range of -40 degrees F to 170 degrees F makes it appropriate for most indoor compressed air installations as well as unheated shop or outdoor enclosure environments. The black color coding is consistent with standard push-to-connect pneumatic fittings used in air-line plumbing.\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 collet-release removal\u003c\/li\u003e\n  \u003cli\u003eRated to 225 psi maximum working pressure for standard compressed air service\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch OD tube size — inline union configuration joins two tube ends\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range of -40 degrees F to 170 degrees F\u003c\/li\u003e\n  \u003cli\u003eBlack color finish consistent with standard pneumatic fitting identification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style push-to-connect union fitting for 1\/4 inch OD tubing used in compressed air and pneumatic control systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by pneumatic or mechanical maintenance technicians. Before servicing any pneumatic line, depressurize the system and verify zero line pressure. Ensure tubing ends are cut cleanly and squarely with no burrs before seating into the fitting. Confirm tubing OD matches the fitting size before final installation to prevent leaks or fitting damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Push-to-Connect\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConfiguration\u003c\/strong\u003e: Union (inline, same-size tube to tube)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 225 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Working Temperature\u003c\/strong\u003e: -40 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 170 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27121700\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: COILHOSE PNEUMATICS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: CL620404\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"COILHOSE PNEUMATICS","offers":[{"title":"Default Title","offer_id":51558618399026,"sku":"CL620404","price":55.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f5dc73bba832e9aab3d56c1a14193ee5.jpg?v=1786416030","url":"https:\/\/voomisupply.com\/products\/coilhose-pneumatics-cl620404-push-to-connect-union-1-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
