Featuring an external seal design and a 1\/8-27 NPTF threaded connection, this valve provides a reliable, leak-resistant seal without relying solely on thread engagement. The brass body resists corrosion and holds up to 150 psi maximum working pressure. Its compact form factor makes it well-suited for tight installations on tanks, manifolds, air receivers, and line equipment. Installation is performed by licensed plumbers, pipefitters, or HVAC technicians depending on the application.\u003c\/p\u003e\n\u003cp\u003eThe DC604-2 is used in residential and light commercial applications where a small-bore shutoff or drain point is needed on pressurized systems. Typical installations include air compressor tanks, pneumatic control lines, condensate drain points on HVAC equipment, and low-pressure hydraulic circuits. The 1\/8-27 NPTF thread is a standard pipe thread size compatible with a wide range of fittings and manifold ports commonly found in trade plumbing and mechanical systems. The external seal design helps maintain a positive shutoff even under system vibration or thermal cycling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eExternal seal design provides reliable shutoff independent of thread-only sealing\u003c\/li\u003e\n  \u003cli\u003e1\/8-27 NPTF thread for standard pipe compatibility\u003c\/li\u003e\n  \u003cli\u003eBrass body construction for corrosion resistance in air and fluid service\u003c\/li\u003e\n  \u003cli\u003e150 psi maximum working pressure rating\u003c\/li\u003e\n  \u003cli\u003eRated for minimum working temperature of -65 degrees F\u003c\/li\u003e\n  \u003cli\u003eCompact size suitable for tight-clearance drain and blowdown locations\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 systems with 1\/8-27 NPTF threaded ports in compressed air, pneumatic, HVAC, and light fluid-handling applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eDepressurize and isolate the system completely before removing or installing this valve. Apply thread sealant or PTFE tape appropriate for the service fluid to the NPTF threads before installation. Hand-tighten first, then use a wrench to bring the fitting to proper engagement without overtightening, which can crack brass fittings. Work should follow applicable plumbing and mechanical codes including IPC and IFGC guidelines where relevant.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\/8-27 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Brass\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\u003eWeight\u003c\/strong\u003e: 0.028 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: DC604-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51544046764338,"sku":"DC604-2","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/def6d7e3f32ddc7cd473f2f1433d033b.jpg?v=1785923242","url":"https:\/\/voomisupply.com\/products\/parker-dc604-2-drain-cock-shutoff-valve-1-8-inch-nptf","provider":"Voomi Supply","version":"1.0","type":"link"}
