POE oils are the standard lubricant choice for systems operating with HFC and HCFC refrigerants, where mineral oil is not compatible with the refrigerant or system design requirements. The 68H viscosity grade is suited to applications that demand a heavier-weight oil for proper film strength and compressor protection. This product ships in a 1-gallon container, making it appropriate for shop stock or multiple service calls. Licensed HVAC-R technicians are the primary users of this lubricant during compressor replacements, system retrofits, and oil top-off procedures.\u003c\/p\u003e\u003cp\u003eEmkarate RL 68H lubricant is used in refrigeration and air conditioning systems where a POE oil of ISO viscosity grade 68 is specified. This includes commercial refrigeration compressors and certain residential and light-commercial HVAC equipment running HFC refrigerants such as R-410A, R-404A, and R-134a, where the OEM or compressor manufacturer specifies a POE oil at this viscosity grade. Always verify the compressor manufacturer's oil specification before adding lubricant to any system.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eEmkarate RL 68H designation — ISO viscosity grade 68, heavier-weight POE formulation for demanding refrigeration applications\u003c\/li\u003e\n\u003cli\u003ePolyolester (POE) base oil — fully miscible with HFC and HCFC refrigerants\u003c\/li\u003e\n\u003cli\u003e1-gallon container suitable for shop stock and multi-unit service work\u003c\/li\u003e\n\u003cli\u003eDesigned for use in hermetic and semi-hermetic compressor systems where POE lubricant is required\u003c\/li\u003e\n\u003cli\u003eFormulated to resist hydrolysis and maintain lubricity under refrigeration operating conditions\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eIntended for refrigeration and air conditioning systems that specify a POE lubricant at ISO viscosity grade 68.

Recover all refrigerant before opening the system for oil service. POE oils are hygroscopic and absorb moisture rapidly when exposed to air — keep the container sealed until point of use and minimize exposure time. Do not mix POE oil with mineral oil or alkylbenzene oil in a system without verifying compatibility with the compressor manufacturer.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Line\u003c\/strong\u003e: Emkarate RL 68H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOil Type\u003c\/strong\u003e: Polyolester (POE)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Viscosity Grade\u003c\/strong\u003e: 68\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContainer Size\u003c\/strong\u003e: 1 gallon\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: NU-CALGON\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4316-46\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NU-CALGON","offers":[{"title":"Default Title","offer_id":51467438096690,"sku":"4316-46","price":97.37,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9d4eba5d26943d38ccd758aa64c68bdd.jpg?v=1783904450","url":"https:\/\/voomisupply.com\/products\/nu-calgon-4316-46-emkarate-rl-68h-lubricant-1-gallon","provider":"Voomi Supply","version":"1.0","type":"link"}
