Part of the R45 series, this regulator accepts a maximum supply pressure of 150 psi and delivers a maximum flow rate of 35 CFM through a 3\/8 inch NPT port. It includes a built-in relief function to vent excess downstream pressure when the set point is exceeded. The plastic body keeps weight low at 0.38 pounds, making it well suited for space-constrained panel or inline installations. Licensed pneumatic system technicians, maintenance mechanics, and industrial service professionals are the typical installers.\u003c\/p\u003e\u003cp\u003eThe R45-03B is used in light-duty and space-sensitive compressed air applications where a compact footprint is required. Its 3\/8 inch NPT end connections and miniature form factor fit well in pneumatic control panels, automation equipment, and point-of-use air lines. The regulator handles compressed air only and is rated for fluid temperatures starting at 40 degrees F minimum. The adjustable pressure range runs from 0 to 60 psi output, making it appropriate for tools, actuators, and instruments that require regulated low-to-medium pressure air supply. No pressure gauge is included, though a 1\/4 inch gauge port is provided for an optional field-installed gauge.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMiniature R45 series body fits tight panel and inline installations\u003c\/li\u003e\n\u003cli\u003e3\/8 inch NPT end connections for direct pipe or fitting assembly\u003c\/li\u003e\n\u003cli\u003e0 to 60 psi adjustable output range from up to 150 psi supply\u003c\/li\u003e\n\u003cli\u003eMaximum flow rate of 35 CFM supports most light industrial pneumatic tools and actuators\u003c\/li\u003e\n\u003cli\u003eIntegral relief function vents excess downstream pressure automatically\u003c\/li\u003e\n\u003cli\u003e1\/4 inch gauge port accepts optional pressure gauge without additional fittings\u003c\/li\u003e\n\u003cli\u003ePlastic construction reduces overall assembly weight to 0.38 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct installation miniature air regulator for compressed air systems using 3\/8 inch NPT porting and requiring a 0 to 60 psi regulated output.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified pneumatic or mechanical technician. Depressurize and lock out the air supply line before removing any existing regulator or fitting the R45-03B into the system. Apply thread sealant appropriate for compressed air service to NPT threads per standard practice. Verify downstream pressure setting with a calibrated gauge 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: R45\u003c\/li\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 inch NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Connections\u003c\/strong\u003e: NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput Pressure Range\u003c\/strong\u003e: 0 to 60 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\u003eMaximum Air Flow\u003c\/strong\u003e: 35 CFM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Function\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGauge Port Thread Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Gauge Included\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFluid Type\u003c\/strong\u003e: Compressed Air\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Temperature\u003c\/strong\u003e: 40 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.38 pounds\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: R45-03B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51540327039282,"sku":"R45-03B","price":118.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/318ec52348f80d453cdc15e2f3b0ff47.jpg?v=1785852293","url":"https:\/\/voomisupply.com\/products\/parker-r45-03b-miniature-air-regulator-3-8-npt-150-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
