It accepts supply pressures up to 150 psi and delivers a regulated output range of 0 to 25 psi, making it well suited for low-pressure pneumatic control applications. The port size is 3\/8 inches NPT, and the compact body measures 2.06 inches wide by 3.43 inches high. Constructed with a plastic body, the unit is lightweight at 0.38 pounds and handles operating temperatures from 40 degrees F to 125 degrees F. Licensed HVAC technicians, plumbers, and industrial maintenance technicians install this type of regulator in compressed air lines requiring stable, reduced outlet pressure.\u003c\/p\u003e\n\u003cp\u003eThis regulator is intended for use in miniature pneumatic circuits where space is limited and precise low-pressure regulation is required. It is rated for water as a fluid type in addition to compressed air, broadening its potential application in light industrial and process control settings. The unit does not include an integral pressure gauge, though a 1\/4 inches gauge port is provided for field installation of a gauge if monitoring is needed. No relief function is incorporated, so downstream pressure relief must be addressed separately in the system design. Typical installations include instrument air panels, small pneumatic actuators, and light-duty compressed air tools requiring output pressures within the 0 to 25 psi range.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMiniature form factor: 2.06 inches wide by 3.43 inches high for space-constrained installations\u003c\/li\u003e\n  \u003cli\u003e150 psi maximum supply pressure with 0 to 25 psi regulated output range\u003c\/li\u003e\n  \u003cli\u003e3\/8 inches NPT port size for standard compressed air line connections\u003c\/li\u003e\n  \u003cli\u003e1\/4 inches gauge port thread for optional downstream pressure monitoring\u003c\/li\u003e\n  \u003cli\u003eRated for both compressed air and water service\u003c\/li\u003e\n  \u003cli\u003eLightweight plastic body at 0.38 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style miniature air regulator for compressed air and water service lines utilizing 3\/8 inches NPT connections and requiring regulated output pressures of 0 to 25 psi at supply pressures up to 150 psi.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified technician familiar with compressed air system safety practices. Depressurize and lock out the air supply before installing or servicing the regulator. Apply thread sealant appropriate for pneumatic service to all NPT connections and verify there are no leaks before returning the system to service. If a pressure gauge is required, install it at the 1\/4 inches gauge port using a compatible fitting rated for the system pressure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRegulator Type\u003c\/strong\u003e: Miniature\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePort Size\u003c\/strong\u003e: 3\/8 inches NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutput Pressure Range\u003c\/strong\u003e: 0 to 25 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Supply Pressure\u003c\/strong\u003e: 150 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGauge Port Thread Size\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFluid Type\u003c\/strong\u003e: Compressed Air, Water\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Function\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Gauge Included\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperating Temperature Range\u003c\/strong\u003e: 40 degrees F to 125 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Plastic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2.06 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 3.43 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.38 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: PARKER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: R46-03AK\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51540688208178,"sku":"R46-03AK","price":107.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c3a7940950ffe01c3ea76f5ea3776812.jpg?v=1785861979","url":"https:\/\/voomisupply.com\/products\/parker-r46-03ak-miniature-air-regulator-3-8-npt-150-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
