Built from brass, it features a 1\/4 inch body diameter and a 3\/8-18 Female NPSF threaded connection. The high flow interchange design allows maximum airflow with minimal pressure drop, making it well suited for demanding pneumatic circuits. It carries a maximum working pressure of 300 psi and handles temperatures from -4 degrees F to 212 degrees F. Licensed HVAC technicians, pipefitters, and maintenance mechanics install this type of coupler in compressed air distribution systems, pneumatic tool setups, and fluid transfer lines.\u003c\/p\u003e\u003cp\u003eThis coupler is intended for threaded pneumatic connections where a high flow, 25 Series interchange coupler is required. Typical installations include compressed air systems in commercial and light industrial facilities, service shop pneumatic tool stations, and maintenance operations where consistent airflow and reliable quick-disconnect performance are critical. The brass construction makes it suitable for general-purpose compressed air, as well as some non-corrosive fluid transfer applications within its rated temperature and pressure range.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHigh flow interchange design minimizes pressure drop across the connection\u003c\/li\u003e\n\u003cli\u003eBrass body construction for durability in general-purpose pneumatic and fluid service\u003c\/li\u003e\n\u003cli\u003e3\/8-18 Female NPSF threaded inlet for secure, leak-resistant connection\u003c\/li\u003e\n\u003cli\u003e1\/4 inch body diameter, part of the Parker 25 Series coupler family\u003c\/li\u003e\n\u003cli\u003eRated to 300 psi maximum working pressure\u003c\/li\u003e\n\u003cli\u003eOperating temperature range: -4 degrees F to 212 degrees F\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or service coupler for pneumatic systems requiring a 25 Series high flow interchange coupler with a 3\/8-18 Female NPSF threaded connection and 1\/4 inch body diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified mechanic or pipefitter familiar with pneumatic system service. Depressurize the air line completely before removing or installing any coupler. Apply thread sealant appropriate for the service medium to the NPSF threads and tighten to the fitting manufacturer's standard recommendation without over-torquing brass fittings. Verify all connections are leak-free before returning the system to service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 25 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\u003eBody Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Female NPSF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 300 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\u003eOverall Length\u003c\/strong\u003e: 2.34 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 0.81 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: 0.27 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: 25KAIN17MPN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51544058691890,"sku":"25KAIN17MPN","price":76.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0ed6cca870e3d177f5fa40570460119d.jpg?v=1785923401","url":"https:\/\/voomisupply.com\/products\/parker-25kain17mpn-pneumatic-coupler-1-4-in-brass-300-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
