It delivers up to 65 ft\/lb of torque at 90 psi operating pressure, running at 350 RPM with an air consumption rate of 3.7 CFM. The inline handle design keeps the tool low-profile and easy to maneuver in confined areas such as engine bays, mechanical rooms, and equipment panels. A 1\/4 inch NPT inlet connects to standard shop air lines. At 2.9 pounds and 12.4 inches in overall length, it balances reach with handling comfort during extended use.\u003c\/p\u003e\n\u003cp\u003eThis air ratchet is suited for automotive, heavy equipment, and industrial maintenance applications where pneumatic tools are standard. It fits into typical shop setups running a 3\/8 inch minimum hose size and a 90 psi compressed air supply. The inline handle makes it a common choice for under-hood work, assembly lines, and service bays where a pistol-grip ratchet would be too bulky. Licensed mechanics, fleet technicians, and industrial maintenance professionals are the primary users.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8 inch drive size compatible with standard 3\/8 inch drive sockets\u003c\/li\u003e\n  \u003cli\u003e65 ft\/lb maximum torque output at 90 psi\u003c\/li\u003e\n  \u003cli\u003eInline handle profile for access in tight and confined spaces\u003c\/li\u003e\n  \u003cli\u003e350 RPM free speed for efficient fastener cycling\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch NPT inlet fits standard shop air fittings\u003c\/li\u003e\n  \u003cli\u003e3.7 CFM air consumption suits most shop compressor setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 3\/8 inch drive sockets and accessories.

Before attaching or removing the tool from an air line, depressurize the line and verify the quick-connect fitting is fully seated. Use thread sealant on NPT fittings to prevent air leaks. Always inspect the air hose and fittings for wear or damage before each use, and operate within the rated 90 psi maximum pressure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandle Type\u003c\/strong\u003e: Inline\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Torque\u003c\/strong\u003e: 65 ft\/lb\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Speed\u003c\/strong\u003e: 350 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAir Pressure\u003c\/strong\u003e: 90 psi (6.20 bar)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAir Consumption\u003c\/strong\u003e: 3.7 CFM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Size\u003c\/strong\u003e: 1\/4 inch NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Hose Size\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 12.4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2.2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.9 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDecibel Rating\u003c\/strong\u003e: 89 dB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112700\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: PROTO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: J138RSH\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROTO","offers":[{"title":"Default Title","offer_id":51542792143154,"sku":"J138RSH","price":558.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7ab9090e78b482822d9e81c5919c9140.jpg?v=1785907572","url":"https:\/\/voomisupply.com\/products\/proto-j138rsh-air-ratchet-3-8-inch-drive-65-ft-lb","provider":"Voomi Supply","version":"1.0","type":"link"}
