MalcoEdge™ M2VKMG Multi-Gas 2 Valve Manifold Kit – Compatible with R22, R134A, R404A, R407C Refrigerants
The MalcoEdge™ M2VKMG Multi-Gas 2 Valve Manifold Kit is engineered for HVAC/R professionals who demand performance and reliability. Compatible with R22, R134A, R404A, and R407C refrigerants, this manifold kit is ideal for servicing a wide range of refrigeration and air conditioning systems.
It includes three 72” Safe Seal hoses: red, blue and yellow indicators with 1/4 SAE connections, ensuring tight, leak-proof connections. The sight glass allows for accurate monitoring of refrigerant flow, while quarter-turn anodized knobs offer smooth operation and corrosion resistance. Valve spring technology increases reliability and extends tool life under frequent use.
With a built-in hook and magnetic strap, the manifold can be easily mounted for hands-free use, helping technicians work more efficiently in tight spaces.

FAQs
Q1: Should I dedicate a gauge set to a specific refrigerant or clean them between service calls?
A1: We recommend using a dedicated manifold per refrigerant for efficiency. Alternatively, clean and flush your manifolds when switching between refrigerants.
Q2: Do you offer manifold recalibration?
A2: No, manifold calibration is not available. Malco recommends replacing the gauges if recalibration is needed.
Q3: What is unique about MalcoEdge manifolds?
A3: MalcoEdge valves are spring loaded, which helps the seals last longer.
Q4: What refrigerants do MalcoEdge multi-gas manifolds work with?
A4: MalcoEdge multi-gas manifolds are compatible with R22, R134A, R404A, and R407C.
Q5: Does hose length matter when pulling a vacuum?
A5: Yes. The shorter the hose and the larger the diameter, the more efficiently the vacuum will be pulled.
Q6: Can I use the same hoses with a variety of refrigerants?
A6: MalcoEdge hoses are compatible with popular refrigerants. However, we do not recommend using multiple refrigerants in the same hoses unless you flush them first using a product like ACE Powerflush. To prevent cross-contamination from oils left in the hoses, we recommend dedicating separate hoses to specific refrigerants.
Q7: Do I need to flush and clean my equipment when switching between refrigerants?
A7: Yes. Some refrigerants use different lubricants and cannot be mixed. As a best practice, flush pumps, hoses, manifolds, and other components between services to prevent cross-contamination. We recommend using ACE Powerflush when switching refrigerants.
