Review: It does suck, vaccum wise... - This thing sure sucks and allowed a vaccum to be pulled for my A/C system repair and charge. Work well. Review: Great vacuum pump - I have been using these pumps for many years, they work great to get down to a deep vacuum. I use multiple of these vacuums with 1/2 vacuum hoses on one system. Pulls down to 500 microns before you know it. I use mine for a year and then retire them with a new one, and at the price point it is worth it. The pumps still work after a year and you can flip the apex seals in the pump to get longer life out of them. ## Features - 6 CFM free air displacement with ultimate vacuum of 80 microns - Refined cartridge machining process creates an improved surface finish extending the longevity of the pump life - Upgraded seals insure maximum vacuum - Easily removable vapor discharge/oil fill port - Large oil level sight glass with max/min level indicator ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01H5O66QA | | Best Sellers Rank | #198,423 in Automotive ( See Top 100 in Automotive ) #85 in Air Conditioning Vacuum Pumps | | Brand | Mastercool | | Brand Name | Mastercool | | Color | Silver | | Customer Reviews | 4.3 out of 5 stars 237 Reviews | | EU Spare Part Availability Duration | 1 years | | Flow Rate | 6 cfm | | Global Trade Identification Number | 00700376113594 | | Included Components | VACUUM PUMP | | Item Type Name | 6 CFM VACUUM PUMP | | Item Weight | 21 pounds | | Manufacturer | Mastercool | | Manufacturer Part Number | 90066-B | | Manufacturer Warranty Description | MANUFACTURERS WARRANTY | | Material | Aluminum | | Material Type | Aluminum | | Model Number | 90066-B | | Number of Items | 1 | | Power Source | Corded Electric | | Product Style | 6 CFM, Single Stage | | Specific Uses For Product | Automotive repair, HVAC service, Construction, Cold weather | | Style | 6 CFM, Single Stage | | UPC | 700376113594 791511182889 | | Unit Count | 1 Count | | Voltage | 12 volts | ## Product Details - **Brand:** Mastercool - **Color:** Silver - **EU Spare Part Availability Duration:** 1 Years - **Global Trade Identification Number:** 00700376113594 - **Item Weight:** 21 Pounds - **Material:** Aluminum - **Maximum Flow Rate:** 6 Cubic Feet Per Minute - **Power Source:** Corded Electric - **Style:** 6 CFM, Single Stage - **Voltage:** 12 Volts ## Images ![MASTERCOOL 90066-B Vacuum Pump - Image 1](https://m.media-amazon.com/images/I/61JZHP9b10L.jpg) ## Available Options This product comes in different **Color, Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ It does suck, vaccum wise... *by P***Y on October 5, 2025* This thing sure sucks and allowed a vaccum to be pulled for my A/C system repair and charge. Work well. ### ⭐⭐⭐⭐⭐ Great vacuum pump *by A***G on June 4, 2021* I have been using these pumps for many years, they work great to get down to a deep vacuum. I use multiple of these vacuums with 1/2 vacuum hoses on one system. Pulls down to 500 microns before you know it. I use mine for a year and then retire them with a new one, and at the price point it is worth it. The pumps still work after a year and you can flip the apex seals in the pump to get longer life out of them. ### ⭐⭐⭐⭐ This is huge! *by J***Y on May 8, 2025* It works but this thing is huge and heavy. Wish I bought the little Robbin Air one. Inexpensive but massive in size. Probably better than harbor freight, maybe not. ## Frequently Bought Together - Mastercool 6 CFM Single Stage Vacuum Pump 90066-B - Mastercool 98210-A Electronic Refrigerant Scale, Black - Mastercool 69110 Automotive A/C Recovery System – SAE J2810 Certified, 30 lb DOT Tank, 1/2 HP Oil-Less Compressor, Automatic Shut-Off, Compatible with R134a, R12, R22, R410A --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.sa/products/42972353-mastercool-90066-b-vacuum-pump](https://www.desertcart.com.sa/products/42972353-mastercool-90066-b-vacuum-pump) --- *Product available on Desertcart Saudi Arabia* *Store origin: SA* *Last updated: 2026-08-19*
