MalcoEdge® Turboflow™ Vacuum Kit – Dual – HHK2
The MalcoEdge® HHK2 Turboflow™ Vacuum Kit – Dual is built for maximum evacuation performance on larger residential and light commercial HVAC and refrigeration systems. Designed for Trade Pros who need faster draw-down and efficient system setup, this kit expands on standard evacuation configurations by enabling high-flow access from both the high and low sides simultaneously.
At the core of the system are two TurboFlow™ refrigerant hoses, each featuring a 3/8 in. inner diameter to maximize flow and reduce evacuation time. At 60 inches in length, the hoses provide flexibility on the job while maintaining manageable handling. Built to SAE J2196 standards, each hose delivers durability in demanding conditions with an 800 psi working pressure and 4000 psi burst rating. Integrated 3/8 in. x 1/4 in. SAE fittings ensure compatibility with standard service ports and manifold connections.
The included high-flow Y branch (3/8 in. x 3/8 in. x 3/8 in.) allows technicians to connect both hoses in parallel to the vacuum pump, increasing available flow and improving evacuation efficiency. Its Y-shaped design creates a smoother flow path compared to traditional T-style fittings, supporting faster system evacuation.
For system access and control, the kit includes both a High-Flow Core Removal Tool with Sight Glass (CRT27Y) and a Compact Core Removal Tool (CRT1). The CRT2Y features a Y-style design for improved flow, an integrated sight glass for verifying refrigerant condition and core capture, and dual valves for isolating and protecting connected vacuum gauges. The CRT1 provides a more compact solution for tighter access points, with a single valve design and the same 20-micron vacuum rating, allowing it to be used in parallel setups where additional valve control is not required.
Both tools support 1/4 in. and 5/16 in. systems with included adapters, offering flexibility across common HVAC applications. Durable construction in both the CRTY27Y and CRT1 includes anodized aluminum bodies with brass valves and fittings for long-term reliability and a magnetic end knob for convenient storage of the core removal rod after removal from the tool body.
All components are organized in a Veto Pro Pac® Hose Hauler bag, designed for durability and efficient transport. The bag features a water- and oil-resistant tarpaulin interior for easy cleanup, multiple storage pockets, removable dividers, and a removable interior pouch for flexible organization. Exterior MOLLE straps and D-rings provide additional attachment points, while a rugged base protects against wear in tough environments.
With dual-hose capability, high-flow Y configuration, and flexible core removal tool options, the HHK2 kit is designed to support faster evacuation, improved system access, and more efficient workflows on larger systems.

FAQs
1 – Turbo Flow 60” 1/4 SAE x 3/8 SAE hose
1 – Dual-valve CRT with sight glass” Q: Where do I connect the CRT and hose to evacuate a system? A: The 3/8″ connector connects to the vacuum pump while the CRT and 1/4″ connector would attach to the high side (liquid line). This allows for air and non condensables to be removed from the system. A vacuum gauge should be connected to the accessory port on the CRT. Q: Is there a magnet to store the core removal stem after it is removed from the CRT? A: Yes, there is a magnet on the CRT core remover. Q: Is the core removal tools vacuum-rated? If so, what is the vacuum rating? A: The core removal tool is rated to 20 microns. Q: Are the core removal tools & high flow Y’s vacuum-rated? If so, what is the vacuum rating? A: The core removal tool and the high flow Y’s are rated to 20 microns. Q: Should I clean or flush my CRT between uses? If so, how do I clean it? A: We recommend using an ACE powerflush product to clean out if the tool has been exposed to lubricants or other contaminants such after servicing a system with a compressor has burned out. Refer to the instructions for the ACE powerflush product for guidance on how to flush these components. Q: Where can I get replacement parts for my CRT? (Core removal rod, spare gaskets, replacement valves, etc.) A: Please contact customer service. Q: I suspect my CRT is leaking, how can I test for this? A: To test a CRT: For this test you will need a vacuum pump, a digital vacuum gauge such as the DVG1, a vacuum hose such as the Turbo flow hoses, and an empty recovery tank. You may also need adapters to size the fittings and recovery tank ports appropriately. Always use known good test equipment to ensure you are testing the CRT, not your test equipment. 1. Close the valves on the evacuated, known-good recovery cylinder.
2. Attach the CRT to the vapor port of the recovery cylinder.
3. Attach the vacuum gauge to the accessory port on the CRT.
4. Connect the vacuum hose to the inline port of the CRT. Connect the other end of the vacuum hose to the vacuum pump.
5. Open the vapor port of the recovery cylinder.
6. Turn on the vacuum pump to start the test.
7. Draw down the system to 200 microns.
8. Close the inline and accessory valves half way. Allow the vacuum pump to draw the system back down to 200 microns. Fully open the accessory valve and inline valve on the CRT and wait 10-15 seconds. close the valves 1/2 way again and check that the vacuum pressure does not rise.
Note: If the vacuum pressure rises, repeat opening and partially closing the valves until the pressure does not rise.
9. Fully open the accessory valve and fully close the inline valve.
10. Turn off the vacuum pump and remove the vacuum hose.
11. Allow the system to rest for 15-20 minutes. The digital vacuum gauge should not rise above 500 microns.
