DVA-1 Adapter

I plan to buy a kit (can with gague bundle)

Kits include a DVA-1 if needed

I bought a kit with a universal gauge and need to buy a refill

Universal gauges never require a DVA-1.

I already own a piercing valve gauge and plan to buy a can of R-134a

You will need a DVA-1 when using these R-134 products:
