Cheap mineral oil ruins expensive pumps. Your $200 vacuum pump deserves better than $5 oil from the auto-parts aisle.\u003c\/p\u003e\u003cp\u003eHCPRO Performance VPO-46 is a \u003cstrong\u003epremium synthetic vacuum pump lubricant\u003c\/strong\u003e with viscosity index 118, ~46 cSt at 40°C, and ultra-low vapor pressure. The additive package combines \u003cstrong\u003eanti-foam, anti-corrosion, anti-oxidation, and anti-wear chemistry\u003c\/strong\u003e specifically formulated for rotary-vane vacuum service. Compatible with \u003cstrong\u003eRobinair, Yellow Jacket, JB Industries, Fieldpiece, HCPRO HCBK-12DC, HCEC-6S, and other rotary vane, scroll, piston, and diaphragm vacuum pumps\u003c\/strong\u003e.\u003c\/p\u003e\u003ch3\u003eWho this oil is for\u003c\/h3\u003e\u003cp\u003eHVAC service techs pulling refrigerant evacuations below 500 microns. Refrigeration contractors servicing commercial cold rooms and walk-ins. Mobile auto A\/C technicians doing recharges. Lab technicians running rotary-vane vacuum equipment. Anyone whose pump cost more than $100 and whose customer expects a clean install.\u003c\/p\u003e\u003ch3\u003eWhen to use it\u003c\/h3\u003e\u003cp\u003eChange after every \u003cstrong\u003e1–3 evacuations\u003c\/strong\u003e or whenever the sight glass shows cloudy, dark, or contaminated oil. Always change before a deep-vacuum job (compressor burnout, large refrigeration system, A2L line set). Use at every \u003cstrong\u003evacuum pump oil change interval\u003c\/strong\u003e the OEM specifies — typically every 20–30 hours of run time for HVAC service pumps. ISO VG 46 is the industry-standard viscosity; verify your pump's spec sheet, but most HVAC vacuum pumps call for this exact grade.\u003c\/p\u003e\u003ch3\u003eWhy synthetic instead of mineral pump oil\u003c\/h3\u003e\u003cp\u003eSynthetic oil resists oxidation, holds viscosity at high pump temperatures, and absorbs significantly less moisture than mineral. The result: \u003cstrong\u003edeeper vacuum, 3–5× longer oil life, and reduced pump wear\u003c\/strong\u003e. Mineral oil starts breaking down within a few hours of operation — synthetic holds for dozens. Mineral foams during deep pulls and caps your achievable vacuum at ~1,000 microns; synthetic with low vapor pressure goes below 100 microns on a clean system.\u003c\/p\u003e\u003cp\u003eAvailable in \u003cstrong\u003equart (32 oz)\u003c\/strong\u003e and \u003cstrong\u003egallon (128 oz)\u003c\/strong\u003e sizes, plus 2-pack, 4-pack, and 12-pack quart presentations for shops and high-volume service techs. \u003cem\u003eManufactured in the USA to OEM vacuum pump lubricant performance standards.\u003c\/em\u003e\u003c\/p\u003e","brand":"HCPRO","offers":[{"title":"Each 32 oz","offer_id":50844554854701,"sku":"02-0028","price":19.15,"currency_code":"USD","in_stock":false},{"title":"32 oz (Pack 2)","offer_id":50844554887469,"sku":"02-0028-2","price":33.5,"currency_code":"USD","in_stock":false},{"title":"32 oz (Pack 4)","offer_id":50844554920237,"sku":"02-0028-4","price":66.25,"currency_code":"USD","in_stock":false},{"title":"32 oz (Pack 12)","offer_id":50844554985773,"sku":"02-0028-12","price":186.99,"currency_code":"USD","in_stock":false},{"title":"Each Gallon 128 oz","offer_id":50844555018541,"sku":"02-0039","price":49.8,"currency_code":"USD","in_stock":false},{"title":"Gallon 128 oz (Pack 4)","offer_id":50844555051309,"sku":"02-0039-4","price":128.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/3799\/5053\/files\/HCPRO_Products__0337_PROD_IMG_B2C_VACUUMPUMPLUB_32_FRONT.jpg?v=1750447324","url":"https:\/\/www.hcproproducts.com\/products\/vacuum-pump-oil-iso-vg46","provider":"HCPRO","version":"1.0","type":"link"}
