BRADLEY Universal Vacuum Pump Oil is a mineral-based, ISO VG 46 vacuum pump oil made for the rotary vane pumps used in air conditioning and refrigeration work. Fresh oil in the sump gives the vanes a clean seal, so the pump can pull down properly instead of fighting moisture left behind by the last job.\u003c\/p\u003e\n\u003cp\u003eIt suits split system installs, heat pump commissioning and commercial service work, where a pump might see several evacuations a week. Keep a bottle in the van and you can change the oil on site instead of limping through the next job on tired oil.\u003c\/p\u003e\n\u003cp\u003eBest for: HVAC installers, refrigeration mechanics, service technicians, and apprentices looking after their first pump.\u003c\/p\u003e\n\u003cp\u003eCompatible with: most rotary vane vacuum pumps used in HVAC\/R service. Check your pump manual for its oil grade and sump capacity before ordering.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0316\/7787\/4235\/files\/ChatGPT-Image-Jun-12-2026-01_02_47-PM-png.webp?v=1791413808\" alt=\"Vacuum Pump Oil ISO VG 46 – 1L \u0026amp; 4L |\" style=\"float: none;\"\u003e\u003c\/p\u003e\n\u003ch2\u003eBRADLEY Universal Vacuum Pump Oil – ISO VG 46\u003c\/h2\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eLow moisture content, so the oil adds as little water as possible to the pump when you start a pull-down.\u003c\/li\u003e\n\u003cli\u003eISO VG 46 viscosity holds up as the pump heats during long evacuations.\u003c\/li\u003e\n\u003cli\u003eThermal and oxidation stability slows breakdown, so the oil lasts longer between changes.\u003c\/li\u003e\n\u003cli\u003eA film that protects the vanes and bearings, reducing wear and extending pump life.\u003c\/li\u003e\n\u003cli\u003eMineral base that suits most rotary vane pumps, so one bottle covers several pumps in a workshop.\u003c\/li\u003e\n\u003cli\u003e1L and 4L sizes, so you can match the bottle to one pump or a whole fleet.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eOil type: mineral-based vacuum pump oil\u003c\/li\u003e\n\u003cli\u003eISO viscosity grade: ISO VG 46\u003c\/li\u003e\n\u003cli\u003eViscosity: approx. 46 cSt at 40°C\u003c\/li\u003e\n\u003cli\u003eRelative density: approx. 0.86\u003c\/li\u003e\n\u003cli\u003eFlash point: 200°C or higher\u003c\/li\u003e\n\u003cli\u003ePour point: -12°C or lower\u003c\/li\u003e\n\u003cli\u003eAppearance: clear oily liquid\u003c\/li\u003e\n\u003cli\u003eSizes: BRA-VPO-1L (1 litre), BRA-VPO-4L (4 litres)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWhat's in the Box\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1 x BRADLEY Universal Vacuum Pump Oil (1 litre or 4 litres, depending on the option selected)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWhy \"Low Moisture\"\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eWater in the oil boils off under vacuum and holds the pump at a higher reading.
