Built from aluminum, this coupler serves as a double-female adapter used in fluid transfer systems where two cam and groove male adapters must be joined. Rated to a maximum operating pressure of 150 psi, it is engineered for demanding industrial and agricultural hose applications. The included NBR gasket handles temperatures from -40 to 212 degrees F, while the aluminum casting is rated from -150 to 250 degrees F, giving installers a broad service range across common process fluids.\u003c\/p\u003e\n\u003cp\u003eThis spool coupler is used in industrial hose assemblies, agricultural irrigation lines, tank truck fluid transfer, and general industrial piping systems requiring quick-connect cam and groove fittings. Both connection points are 3-inch female coupler ends, making it a direct inline adapter between two male adapters in a hose or pipe run. It is a standard component in petroleum, water, and chemical transfer setups where fast connect and disconnect cycles are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType DD cam and groove spool coupler joins two female coupler ends inline\u003c\/li\u003e\n  \u003cli\u003e3-inch female coupler on both ends for symmetric connection\u003c\/li\u003e\n  \u003cli\u003eAluminum construction offers lightweight corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eRated to 150 psi maximum operating pressure\u003c\/li\u003e\n  \u003cli\u003eNBR gasket rated -40 to 212 degrees F for broad fluid compatibility\u003c\/li\u003e\n  \u003cli\u003eCasting rated from -150 to 250 degrees F for wide temperature service\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Type DD cam and groove spool coupler compatible with 3-inch male cam and groove adapters following MIL-C-27487 and ANSI\/ASME B1.20.1 cam and groove coupling standards commonly used in industrial and agricultural hose systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a plumber, pipefitter, or industrial maintenance technician. Verify that the mating male adapters are free of debris and that the gasket is properly seated before engaging the cam arms. Relieve all system pressure before connecting or disconnecting cam and groove couplings. Inspect the NBR gasket regularly and replace it if cracking, swelling, or deformation is observed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size 1\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type 1\u003c\/strong\u003e: Female Coupler\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size 2\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type 2\u003c\/strong\u003e: Female Coupler\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Operating Pressure\u003c\/strong\u003e: 150 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGasket Temperature Range\u003c\/strong\u003e: -40 to 212 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCasting Temperature Range\u003c\/strong\u003e: -150 to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGasket Material\u003c\/strong\u003e: NBR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoupling Type\u003c\/strong\u003e: Type DD\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: MIDLAND INDUSTRIES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: DD-3030-A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MIDLAND INDUSTRIES","offers":[{"title":"Default Title","offer_id":67951561179442,"sku":"DD-3030-A","price":98.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a0cb5b1d2495c12a3db488557c08898f_9c17badc-e4a7-4f39-8a26-f9b0f8811c12.jpg?v=1791730163","url":"https:\/\/voomisupply.com\/products\/midland-industries-dd-3030-a-cam-groove-spool-coupler-3in","provider":"Voomi Supply","version":"1.0","type":"link"}
