Constructed from brass, Buna-N, and nylon, it transitions between a 5\/8 inch and 1\/2 inch outside diameter tube and is rated to 250 psi maximum working pressure. The push-to-connect design allows a technician to seat the tube with a single push and release it with a collar retract, reducing installation time on service calls. This fitting is installed by HVAC technicians, plumbers, and mechanical contractors working on refrigeration lines, compressed air distribution, and water supply systems.\u003c\/p\u003e\n\u003cp\u003eThe 37PTCSP-10-8 is suited for residential and light commercial applications where a reliable stem-to-tube transition is needed without threading or soldering. Typical installations include compressed air lines, HVAC condensate or fluid circuits, and inline plumbing connections requiring a 5\/8 inch to 1\/2 inch OD reduction. The combination of brass body with Buna-N seals makes it compatible with water, air, and many common refrigerants or light hydraulic fluids encountered in trade work.\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 release\u003c\/li\u003e\n  \u003cli\u003e250 psi maximum working pressure rating\u003c\/li\u003e\n  \u003cli\u003eTransitions 5\/8 inch OD tube to 1\/2 inch OD stem connection\u003c\/li\u003e\n  \u003cli\u003eBrass body construction for corrosion resistance and durability\u003c\/li\u003e\n  \u003cli\u003eBuna-N seals provide reliable performance with water, air, and light fluids\u003c\/li\u003e\n  \u003cli\u003eNylon collar component for secure tube retention and smooth release\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style push-to-connect stem adapter for use in fluid and pneumatic tubing systems requiring a 5\/8 inch by 1\/2 inch OD connection point.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed plumbers, HVAC technicians, or mechanical contractors. Before servicing any line, depressurize the system completely and verify zero pressure before inserting or removing the fitting. Ensure tube ends are cut cleanly and squarely with a proper tube cutter and that all burrs are removed before insertion to ensure a leak-free seal. Follow applicable IPC and IFGC guidelines for pressure testing after installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass, Buna-N, Nylon\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 5\/8 x 1\/2 inches OD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 250 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 2.44 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.05 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2.44 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.062 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: PARKER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 37PTCSP-10-8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51540540096818,"sku":"37PTCSP-10-8","price":16.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/948f1ce45112d7e513dd4cc7e9f0b8ec.jpg?v=1785857924","url":"https:\/\/voomisupply.com\/products\/parker-37ptcsp-10-8-stem-adapter-fitting-5-8x1-2-in-250-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
