It threads directly into a reservoir vent port using a standard MNPT connection, filtering incoming air as fluid levels rise and fall during normal system operation. The plastic housing measures 3-7\/8 inches in diameter and stands 10.7 inches tall, making it a practical fit for a range of industrial and mobile hydraulic applications. Rated for operation down to -40 degrees F, it remains functional in cold-weather field conditions. Licensed maintenance technicians and fluid power specialists are the primary installers.\u003c\/p\u003e\u003cp\u003eThis breather is suited for use on hydraulic power units, industrial gear drives, and fluid storage tanks where airborne moisture and dust ingestion are primary concerns. It is commonly installed in both indoor and outdoor environments where temperature swings cause reservoirs to breathe repeatedly over the course of a shift. The MNPT thread standard makes installation straightforward on any reservoir vent port machined or adapted to accept a male NPT fitting. The single-unit package quantity supports direct one-for-one replacement on existing equipment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDesiccant media removes moisture from air entering the reservoir during fluid level changes\u003c\/li\u003e\n\u003cli\u003eMNPT thread connection for direct installation into standard reservoir vent ports\u003c\/li\u003e\n\u003cli\u003e3-7\/8 inch diameter plastic housing is lightweight and corrosion-resistant\u003c\/li\u003e\n\u003cli\u003eRated to -40 degrees F for cold-climate and outdoor service\u003c\/li\u003e\n\u003cli\u003e10.7 inch height provides adequate desiccant capacity for extended service intervals\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement desiccant breather for hydraulic reservoirs, gearboxes, and fluid storage vessels equipped with a standard MNPT vent port fitting.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified fluid power technician or maintenance professional. Depressurize and isolate the reservoir before removing the existing breather to prevent fluid spillage or pressure release. Use appropriate thread sealant rated for the fluid type and verify the MNPT port size matches before torquing the fitting by hand and then snugging with a wrench. Inspect the desiccant color indicator regularly and replace the breather when the media is fully saturated.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: MNPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 3-7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 10.7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3.87 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3.87 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Operating Temperature\u003c\/strong\u003e: -40 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.7 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: 934332\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51541380890930,"sku":"934332","price":259.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/293bb3841e2505ac87633950f7e4dc7f.jpg?v=1785874203","url":"https:\/\/voomisupply.com\/products\/parker-934332-desiccant-breather-3-7-8-in-mnpt","provider":"Voomi Supply","version":"1.0","type":"link"}
