It features a 3\/8-18 NPTF threaded connection and is rated to 150 psi maximum working pressure. The brass body provides corrosion resistance and durability across a wide service temperature range, down to -65 degrees F. Licensed plumbers and pipefitters install this valve in compressed air lines, water distribution systems, and other low-to-medium pressure fluid circuits where a reliable drain or bleed point is required.\u003c\/p\u003e\n\u003cp\u003eThis drain cock is suited for residential and light commercial plumbing applications. Typical uses include tank drain ports, boiler drain points, compressed air system low points, and inline shutoff service in copper or threaded pipe assemblies. The NPTF thread form creates a pressure-tight seal on metal-to-metal contact, reducing reliance on thread sealants in many installations. The compact size and lightweight construction make it easy to fit in tight equipment bays or mechanical spaces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e150 psi maximum working pressure rating\u003c\/li\u003e\n  \u003cli\u003e3\/8-18 NPTF male pipe thread for pressure-tight metal-to-metal seating\u003c\/li\u003e\n  \u003cli\u003eBrass body construction for corrosion resistance in water and air service\u003c\/li\u003e\n  \u003cli\u003eWide temperature range with minimum working temperature of -65 degrees F\u003c\/li\u003e\n  \u003cli\u003eCompact, lightweight design at approximately 0.13 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation drain cock for threaded pipe systems using 3\/8-18 NPTF connections in plumbing, compressed air, and fluid-handling applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed plumber or qualified pipefitter. Shut off system pressure and drain the line before removing any existing fitting or installing this valve. Apply thread sealant or PTFE tape as required by local plumbing codes, though NPTF threads are designed for dry sealing on metal seats. Verify the system working pressure does not exceed the 150 psi rating before returning the line to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: NPTF Male Pipe\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-18 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 150 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Working Temperature\u003c\/strong\u003e: -65 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.13 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: PARKER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: DC603-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51539064783154,"sku":"DC603-6","price":24.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/01202c9d30f7bba09cd2736372a6bb87.jpg?v=1785834134","url":"https:\/\/voomisupply.com\/products\/parker-dc603-6-brass-drain-cock-shutoff-valve-3-8-in-nptf","provider":"Voomi Supply","version":"1.0","type":"link"}
