It features a 3\/8-inch SAE 45-degree male flared inlet on one end and a 1\/4-inch male NPTF connection on the other. Built from brass, this connector is rated for temperatures from -65 to 250 degrees F and measures 1.35 inches in length. Plumbers, HVAC technicians, and refrigeration service pros install this fitting in fuel, refrigerant, and gas line assemblies where backflow prevention at the connection point is required.\u003c\/p\u003e\n\u003cp\u003eThe 10133 is suited for use in residential and light commercial applications involving SAE 45-degree flare systems. Common installation scenarios include refrigeration line sets, LP and natural gas appliance connections, and pneumatic or hydraulic circuits where a compact inline check valve at a threaded-to-flare transition is needed. Its male NPTF thread provides a dry-seal connection that resists leakage without relying solely on thread sealant.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSAE 45-degree male flared inlet (3\/8-inch) for leak-resistant flare connections\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch male NPTF dry-seal thread on outlet end\u003c\/li\u003e\n  \u003cli\u003eBrass construction for corrosion resistance and durability in fuel, gas, and refrigerant service\u003c\/li\u003e\n  \u003cli\u003eWide operating temperature range: -65 to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eCompact body: 1.35 inches long, 0.65 inches wide, 0.6 inches tall\u003c\/li\u003e\n  \u003cli\u003eBall check mechanism prevents backflow without an external valve\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for SAE 45-degree flare systems requiring a 3\/8-inch male flared to 1\/4-inch male NPTF transition with integrated backflow prevention.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed plumber, HVAC technician, or refrigeration mechanic. Shut off and depressurize the line before making or breaking any flare or threaded connection. Apply thread sealant or PTFE tape to the NPTF threads as appropriate for the service fluid, and use a backup wrench on the fitting body to avoid twisting the line. Verify flow direction before tightening; the ball check allows flow in one direction only.\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\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type 1\u003c\/strong\u003e: Male Flared (SAE 45 degrees)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size 2\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type 2\u003c\/strong\u003e: Male NPTF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTemperature Range\u003c\/strong\u003e: -65 to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.35 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.65 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.085 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: MIDLAND INDUSTRIES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 10133\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MIDLAND INDUSTRIES","offers":[{"title":"Default Title","offer_id":67950305739058,"sku":"10133","price":32.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9b93ff600e42b980ba7fb8b6a1ba702b_46dd2b6e-c131-4b6f-88ca-2e904756f090.jpg?v=1791712579","url":"https:\/\/voomisupply.com\/products\/midland-industries-10133-ball-check-connector-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
