It accepts 3\/8-inch OD tubing and threads into a 1\/4-inch NPT port, creating a secure, tool-free tube connection. The body combines glass-reinforced nylon with nickel-plated brass internal components, giving the fitting the structural strength and corrosion resistance required for industrial and shop pneumatic lines. Rated to 225 psi maximum working pressure, it handles the demands of typical compressed air service without modification. HVAC techs, plumbers, and industrial maintenance technicians use fittings like this to route pneumatic control tubing in both new installations and retrofit work.\u003c\/p\u003e\n\u003cp\u003eThis connector is suited for pneumatic control and fluid transfer lines in commercial and light industrial environments. It is appropriate for applications where quick tube insertion and positive retention are needed without the use of ferrules or compression sleeves. The -40 degrees F minimum working temperature and 170 degrees F maximum working temperature rating make it compatible with most indoor compressed air and pneumatic control circuits found in HVAC, manufacturing, and facility maintenance settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePush-to-connect design allows tool-free tube insertion for fast assembly and servicing\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 NPT male thread for direct connection to standard pneumatic ports and manifolds\u003c\/li\u003e\n  \u003cli\u003eAccepts 3\/8-inch OD tubing without additional ferrules or fittings\u003c\/li\u003e\n  \u003cli\u003eGlass-reinforced nylon and nickel-plated brass construction resists corrosion and mechanical wear\u003c\/li\u003e\n  \u003cli\u003eWide operating temperature range of -40 degrees F to 170 degrees F\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style push-to-connect replacement connector for pneumatic tubing systems using 3\/8-inch OD tubing and 1\/4-inch NPT ported components.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eDepressurize and lock out the compressed air supply before removing or installing pneumatic fittings. Verify the receiving port thread type is NPT before installation, as BSPT threads require a different fitting. Insert tubing fully until it seats against the internal stop before pressurizing the line. Inspect the tubing end for squareness and burrs prior to insertion to ensure a leak-free seal.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: NPT\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\u003eMaterial\u003c\/strong\u003e: Glass-Reinforced Nylon, Nickel-Plated Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.005 pounds\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: CL680604\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"COILHOSE PNEUMATICS","offers":[{"title":"Default Title","offer_id":51563746427186,"sku":"CL680604","price":16.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/402b77ec8fc666da75326ffd3ed64767.jpg?v=1786502419","url":"https:\/\/voomisupply.com\/products\/coilhose-pneumatics-cl680604-push-to-connect-fitting","provider":"Voomi Supply","version":"1.0","type":"link"}
