Used in conjunction with our DV-22N and DV-29, the SH-35N ensures a leak proof setup. The DV-29 consists of one each of the following:
10" (25.4 cm) metal hose with O-Ring quick couplers
Ball valve with O-Ring quick coupler with depressor
90degree Male flare with 1/4" O-ring quick coupler
Valve assembly with 1/4" male flare connections
JB's DV-29 works with all micron gauges and creates a closed system, eliminating any leakage under deep vacuum. 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 3' (91.4 cm) dedicated hose, you will get a lowerreading as the gauge is sensing what the pump is doing and not what the pump is doing to the system.
