Constructed from brass with a threaded female NPSF connection, this coupler features a 1\/8-27 thread size and a body diameter of 0.125 inches. It is rated for a maximum working pressure of 250 psi and operates across a temperature range of -4 degrees F to 212 degrees F. The 21KAIN10MPN is a single-unit component installed by maintenance technicians, pipefitters, and pneumatic system specialists in both light industrial and commercial applications.\u003c\/p\u003e\u003cp\u003eThis coupler is suited for pneumatic hose assemblies and quick-connect systems where high-flow performance is required. Its brass construction makes it appropriate for dry compressed air lines in workshop, manufacturing, and maintenance environments. The threaded female NPSF interface ensures a secure, leak-resistant connection to compatible male fittings. It is typically used where a reliable coupler-to-tool or coupler-to-hose connection is needed at the 1\/8 inch port size.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHigh-flow interchange type for improved air volume delivery\u003c\/li\u003e\n\u003cli\u003eFemale NPSF threaded connection, 1\/8-27 thread size\u003c\/li\u003e\n\u003cli\u003eBrass body construction for corrosion resistance in air service\u003c\/li\u003e\n\u003cli\u003eRated to 250 psi maximum working pressure\u003c\/li\u003e\n\u003cli\u003eWide operating temperature range: -4 degrees F to 212 degrees F\u003c\/li\u003e\n\u003cli\u003eCompact 0.55 inch hex size for easy wrench installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement coupler for pneumatic hose and quick-connect systems using the Parker 21 Series high-flow interchange standard with 1\/8-27 female NPSF threaded ports.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified technician or pipefitter familiar with pneumatic system assembly. Depressurize and isolate the air supply before servicing any fittings or couplers. Use an appropriate wrench on the hex to achieve a snug, leak-free connection; do not overtighten brass fittings. Apply thread sealant or PTFE tape as required by the applicable piping code for the installation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 21 Series\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoupling Type\u003c\/strong\u003e: Coupler\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterchange Type\u003c\/strong\u003e: High Flow\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Female NPSF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/8-27\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 0.55 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 250 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Temperature\u003c\/strong\u003e: 212 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Temperature\u003c\/strong\u003e: -4 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0652 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 40141734\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PARKER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 21KAIN10MPN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51544515510578,"sku":"21KAIN10MPN","price":35.91,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/55096ce75e310aa3336978c934b3d4c5.jpg?v=1785928566","url":"https:\/\/voomisupply.com\/products\/parker-21kain10mpn-pneumatic-coupler-1-8-27-female-npsf-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
