It features a 4ORB (OR B) male inlet on one end and a female outlet on the other, making it the perfect companion for DeatschWerks DW810 male inlet fittings or similar AN-style fuel system components. This check valve ensures fuel flows in one direction only, protecting pumps, regulators, and injectors from reverse flow during shutdown or pressure changes. Built to DeatschWerks’ rigorous standards, it offers minimal restriction, reliable sealing, and durable construction for high-performance and racing applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e4ORB Male to Female Design\u003c\/strong\u003e – Direct compatibility with DW810 male inlet fittings and standard AN plumbing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOne-Way Check Valve\u003c\/strong\u003e – Prevents harmful backflow in fuel systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Flow Construction\u003c\/strong\u003e – Minimal pressure drop for maximum fuel delivery\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable Materials\u003c\/strong\u003e – Engineered for reliability in high-pressure performance environments\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlug-and-Play Fit\u003c\/strong\u003e – Simple integration into existing DeatschWerks or AN fuel systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ctable width=\"100%\" cellspacing=\"0\" cellpadding=\"8\" border=\"1\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eSpec\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003e6-02-0450-B\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eDeatschWerks\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003e4ORB Male to Female Check Valve\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatibility\u003c\/td\u003e\n\u003ctd\u003eUse with DW810 Male Inlet or standard 4ORB\/AN fuel systems\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eThread Size\u003c\/td\u003e\n\u003ctd\u003e4ORB (OR B) Male to Female\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCountry of Origin\u003c\/td\u003e\n\u003ctd\u003eUnited States\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003eDeatschWerks Limited Warranty\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch4\u003eWhats Included\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eDeatschWerks 4ORB Male to Female Check Valve\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eProduct Notes\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eDesigned to prevent backflow in fuel systems when used with DW810 male inlet fittings\u003c\/li\u003e\n\u003cli\u003eHigh-flow design minimizes restriction for maximum performance\u003c\/li\u003e\n\u003cli\u003eIdeal for custom fuel systems, return-style setups, or high-pressure applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eThread into compatible 4ORB female port or DW810 male inlet\u003c\/li\u003e\n\u003cli\u003eUse appropriate thread sealant (anaerobic recommended for fuel systems)\u003c\/li\u003e\n\u003cli\u003eEstimated time: 10–20 minutes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eWhy Choose DeatschWerks Check Valves?\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003ePrecision-machined for reliable one-way flow in high-performance fuel systems\u003c\/li\u003e\n\u003cli\u003eMinimal pressure drop for maximum fuel delivery\u003c\/li\u003e\n\u003cli\u003eTrusted by enthusiasts and professional builders for quality and durability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003e\u003cstrong\u003eFrequently Asked Questions\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eQ:\u003c\/strong\u003e What is this check valve used for?
