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":47712937869484,"sku":"02-0028","price":19.15,"currency_code":"USD","in_stock":true},{"title":"32 oz (Pack 2)","offer_id":47712937902252,"sku":"02-0028-2","price":33.5,"currency_code":"USD","in_stock":true},{"title":"32 oz (Pack 4)","offer_id":47712937935020,"sku":"02-0028-4","price":66.25,"currency_code":"USD","in_stock":true},{"title":"32 oz (Pack 12)","offer_id":47712937967788,"sku":"02-0028-12","price":186.99,"currency_code":"USD","in_stock":true},{"title":"Each Gallon 128 oz","offer_id":47712938000556,"sku":"02-0039","price":49.8,"currency_code":"USD","in_stock":false},{"title":"Gallon 128 oz (Pack 4)","offer_id":47712938033324,"sku":"02-0039-4","price":128.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0697\/1293\/7132\/files\/HCPRO_Products__0337_PROD_IMG_B2C_VACUUMPUMPLUB_32_FRONT_622f13ca-850d-4d5e-9308-17a7915cbd4d.jpg?v=1793019810","url":"https:\/\/splypro.com\/products\/hcpro-vpo-46-synthetic-vacuum-pump-oil","provider":"SPLYPRO","version":"1.0","type":"link"}
