Machined from brass and finished with a nickel plating for added corrosion resistance, this coupling handles pressures up to 1200 psi and operates across a temperature range of -65 to 250 degrees F. Both connection ports are 1\/4 in Female NPTF with a 1\/4-18 thread pitch. The compact body measures approximately 0.88 inches in length with a 0.63-inch hex for wrench engagement. Licensed plumbers and pipefitters install this fitting in fuel, hydraulic, and general fluid-transfer lines.\u003c\/p\u003e\n\u003cp\u003eThis coupling is suited for residential and light commercial plumbing, pneumatic, and fluid-system applications where a reliable inline NPTF connection is required. The NPTF thread form creates a pressure-tight mechanical seal without relying solely on thread sealant, making it appropriate for gas, oil, air, and water service lines. Compatible pipe materials include brass, bronze, copper, steel, aluminum, and iron pipe, giving it broad utility across mixed-material installations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBrass body with nickel-plated finish for corrosion resistance in demanding service environments\u003c\/li\u003e\n  \u003cli\u003e1200 psi maximum working pressure for high-demand fluid and pneumatic lines\u003c\/li\u003e\n  \u003cli\u003e1\/4 in Female NPTF x 1\/4 in Female NPTF with 1\/4-18 thread pitch for a mechanical pressure-tight seal\u003c\/li\u003e\n  \u003cli\u003eWide temperature rating of -65 to 250 degrees F covers both cold and moderate-heat applications\u003c\/li\u003e\n  \u003cli\u003e0.63-inch hex flat allows standard open-end or adjustable wrench engagement\u003c\/li\u003e\n  \u003cli\u003eCompact 0.88-inch body length suits tight-clearance installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with brass, bronze, copper, steel, aluminum, and iron pipe in fuel, air, water, and general fluid-transfer systems requiring a 1\/4 in Female NPTF straight coupling connection.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed plumber or pipefitter. Shut off and depressurize the line completely before removing or installing any fitting. Apply an appropriate thread sealant or PTFE tape in accordance with the system fluid type and local code requirements, even though the NPTF thread form is designed to seal on contact. Do not overtighten  -  use the hex flats and a properly sized wrench; avoid pipe wrenches on the hex body that could deform the fitting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size 1\u003c\/strong\u003e: 1\/4 in\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type 1\u003c\/strong\u003e: Female NPTF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size 2\u003c\/strong\u003e: 1\/4 in\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type 2\u003c\/strong\u003e: Female NPTF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Pitch\u003c\/strong\u003e: 1\/4-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Pressure\u003c\/strong\u003e: 1200 psi\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\u003eBody Length\u003c\/strong\u003e: 0.88 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 0.63 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass, Nickel-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 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: 06103-04-003\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MIDLAND INDUSTRIES","offers":[{"title":"Default Title","offer_id":67948362268978,"sku":"06103-04-003","price":15.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/464ed06563a3a25d8bb9c19db236bf1a_e13116b7-e662-417b-9197-ea06879b492b.jpg?v=1791662851","url":"https:\/\/voomisupply.com\/products\/midland-industries-06103-04-003-brass-pipe-coupling-1-4in-nptf","provider":"Voomi Supply","version":"1.0","type":"link"}
