Mastercool 94261-JT - Black Series Mini-Fold Compact 2-Way Digital HVAC Manifold with In-Line Ball Valve 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 94261-JT kit includes 3 x 60" (150cm) hoses with in-line ball valves, specifically configured for R410A/R32 systems with 5/16" fittings on red/blue hoses.
