Mastercool 94661 - Black Series Mini-Fold Compact 2-Way Digital HVAC Manifold with Hoses

Big Digital Power. Palm-Sized Portability.

Ditch the heavy manifold for small jobs. The Mastercool Black Series Mini-Fold is the ultimate "grab-and-go" solution for the modern HVAC engineer. Whether you are working on a domestic fridge (R600a), a heat pump (R290/R32), or a commercial VRF (R410A/R454B), this compact unit puts precise digital calculations in the palm of your hand. Machined from a solid block of black anodised aluminium, it is tough enough for the van but light enough to carry up a ladder without thinking twice. This 94661 kit includes 3 x 60" (150cm) high pressure hoses and zippered carry case.
