JB Industries DV-29 Leak Proof Hook Up Kit, For Use With DV-22N and SH-35N, Manifold Gauge Set and Charging Hose, 4 Pieces, Domestic

Used in conjunction with our digital micron gauges DV-40 or DV-22N and our superheat/sub cooling gauge SH-35N, the DV-29 ensures a leak proof setup. The DV-29 eliminates other problems when attaching the micron gauge into the system. If the micron gauge is attached directly to the vacuum pump or with a 3' (91.4 cm) dedicated hose, you will get a lower reading as the gauge is sensing what the pump is doing and not what the pump is doing to the system.
