The unit holds 1.75 ounces (52 mL) of grease in its reservoir and uses a variable-pressure spring mechanism to maintain consistent lubricant delivery without manual intervention. The 1\/4 NPTF shank thread provides a leak-resistant tapered connection to standard grease fittings and ports. It is installed by maintenance technicians and millwrights servicing rotating equipment, conveyor systems, and general plant machinery.\u003c\/p\u003e\n\u003cp\u003eThis lubricator is suited for continuous-duty lubrication applications where periodic manual greasing is impractical. It performs across an operating temperature range of -40 to 65.56 degrees C and at operating pressures between 0.21 and 0.46 bar. Typical installations include electric motor bearings, fan shaft housings, conveyor head pulleys, and other equipment requiring steady low-volume grease supply. The spring-loaded design eliminates the need for external pressure sources, making it practical in remote or hard-to-access mounting locations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1.75 oz (52 mL) reservoir capacity for extended service intervals\u003c\/li\u003e\n  \u003cli\u003eSpring-loaded operation delivers consistent grease pressure without an external supply\u003c\/li\u003e\n  \u003cli\u003eIncludes 3 variable pressure springs to allow adjustment of lubricant feed rate\u003c\/li\u003e\n  \u003cli\u003e1\/4 NPTF tapered thread provides a secure, leak-resistant connection\u003c\/li\u003e\n  \u003cli\u003eRated for operating temperatures from -40 to 65.56 degrees C\u003c\/li\u003e\n  \u003cli\u003eCompact design suited for tight or hard-to-reach mounting points\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-install grease cup lubricator for equipment with 1\/4 NPTF lubrication ports requiring a spring-loaded, manual-reservoir greasing solution.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall by a qualified maintenance technician or millwright following applicable equipment lockout\/tagout procedures before servicing any rotating or pressurized components. Thread the 1\/4 NPTF shank into the lubrication port by hand until snug, then tighten with the appropriate wrench — do not overtighten tapered pipe threads. Select the appropriate variable pressure spring from the three included options based on the equipment manufacturer's recommended grease feed rate. Inspect the reservoir seal and spring assembly at each refill to confirm proper seating and prevent lubricant bypass.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReservoir Capacity\u003c\/strong\u003e: 1.75 oz (52 mL)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperation Type\u003c\/strong\u003e: Spring-Loaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Thread Size\u003c\/strong\u003e: 1\/4 NPTF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperating Temperature Range\u003c\/strong\u003e: -40 to 65.56 degrees C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperating Pressure Range\u003c\/strong\u003e: 0.21 to 0.46 bar\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: 3 Variable Pressure Springs\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.6 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: ALEMITE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 43570-A2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALEMITE","offers":[{"title":"Default Title","offer_id":51542066823474,"sku":"43570-A2","price":425.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3b37f5114d744000fb0fbfa41a4742d0.jpg?v=1785891071","url":"https:\/\/voomisupply.com\/products\/alemite-43570-a2-grease-cup-lubricator-1-75-oz-1-4-nptf","provider":"Voomi Supply","version":"1.0","type":"link"}
