It features an external seal design with a 1\/4-18 NPTF threaded connection and is rated for a maximum working pressure of 150 psi. The valve body is machined from brass, providing reliable corrosion resistance in typical hydraulic, pneumatic, and plumbing service. Licensed plumbers, HVAC technicians, and fluid power mechanics install this type of drain cock when a compact, low-profile shutoff and drain point is required in a pressurized line or equipment port.\u003c\/p\u003e\u003cp\u003eThis drain cock is suited for residential and light commercial applications where a reliable drain or bleed point is needed on water lines, compressed air systems, boiler drain ports, or HVAC equipment. Its NPTF thread form provides a pressure-tight mechanical seal on connection, making it appropriate for systems where leak-free performance is critical without relying solely on thread sealant. The compact form factor fits in tight equipment bays and panel installations common in HVAC and plumbing rough-in work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eExternal seal design provides a reliable shutoff and drain function in a single compact valve\u003c\/li\u003e\n\u003cli\u003e1\/4-18 NPTF thread ensures a pressure-tight connection on both male and female fittings\u003c\/li\u003e\n\u003cli\u003eBrass body construction offers corrosion resistance for water, air, and compatible fluid service\u003c\/li\u003e\n\u003cli\u003eRated to 150 psi maximum working pressure\u003c\/li\u003e\n\u003cli\u003eMinimum working temperature of -65 degrees F supports cold-environment installations\u003c\/li\u003e\n\u003cli\u003eLightweight construction at approximately 0.046 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or service fitting for systems using 1\/4-18 NPTF drain cock connections in plumbing, HVAC, and compressed air applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or qualified HVAC technician in accordance with applicable IPC or IFGC requirements. Shut off system pressure and relieve any residual pressure before removing or installing a drain cock. Apply thread sealant or PTFE tape as appropriate for the service fluid, noting that NPTF threads are designed for metal-to-metal sealing but sealant is commonly used in practice. Do not overtighten brass fittings, as the material is susceptible to thread damage under excessive torque.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: NPTF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-18 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: 0.046 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: DC606-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51542378348850,"sku":"DC606-4","price":16.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/747d0a77761681126b92df73856c277e.jpg?v=1785899059","url":"https:\/\/voomisupply.com\/products\/parker-dc606-4-drain-cock-shutoff-valve-1-4-18-nptf-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
