Built from brass, it provides a reliable mechanical grip on tubing without requiring a flared end. The assembly measures 0.37 inches in length with a 0.56-inch hex profile and carries a 1\/2-24 thread size. It is rated for pressures up to 300 psi and a temperature range of -65 degrees F to 250 degrees F, making it suitable for a broad range of service conditions. Plumbers, pipefitters, and HVAC technicians working with compression-style fittings install this component as part of flareless tube assemblies.\u003c\/p\u003e\n\u003cp\u003eThis assembly is suited for residential and light commercial plumbing, refrigeration, and instrumentation tubing applications where flareless compression connections are specified. It is compatible with aluminum tubing, copper tubing, and hard plastic tubing when used with a brass sleeve. The minimum tube wall thickness required is 0.049 inches. Typical install scenarios include hydraulic lines, control tubing, and low-pressure pneumatic circuits where a clean, vibration-resistant connection is needed without flaring equipment on site.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFlareless design eliminates the need for a tube flaring tool during assembly\u003c\/li\u003e\n  \u003cli\u003eBrass construction resists corrosion in both liquid and gas service\u003c\/li\u003e\n  \u003cli\u003eRated to 300 psi for reliable performance in low-to-medium pressure systems\u003c\/li\u003e\n  \u003cli\u003eWide temperature range of -65 degrees F to 250 degrees F covers most HVAC and plumbing environments\u003c\/li\u003e\n  \u003cli\u003eCompatible with aluminum, copper, and hard plastic tubing when paired with a brass sleeve\u003c\/li\u003e\n  \u003cli\u003e1\/2-24 thread size with 0.56-inch hex for standard wrench engagement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with aluminum tubing, copper tubing, and hard plastic tubing with a brass sleeve.

Depressurize and isolate the line before disassembly or installation. Use a properly sized open-end or adjustable wrench on the 0.56-inch hex; do not overtighten, as brass threads can be damaged by excessive torque. Verify tubing wall thickness meets the 0.049-inch minimum before assembly to ensure a leak-free connection.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Flareless\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Pressure\u003c\/strong\u003e: 300 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTemperature Range\u003c\/strong\u003e: -65 degrees F to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.37 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 0.56 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Tube Wall Thickness\u003c\/strong\u003e: 0.049 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 20231\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MIDLAND INDUSTRIES","offers":[{"title":"Default Title","offer_id":67948929220914,"sku":"20231","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/983caaad31f3650214d6f872b5b9ef5a.jpg?v=1791677039","url":"https:\/\/voomisupply.com\/products\/midland-industries-20231-3-8-in-flareless-brass-nut-sleeve-assembly","provider":"Voomi Supply","version":"1.0","type":"link"}
