Adaptor R410A (5/16"Flare, also known as 1/2"-20 UNF) to R134A (1/4"Flare) Male or Female Version.

With so many dedicated R410A Manifold & Gauges sets available these days, these adaptors are useful for converting flare sizes in male or female versions to the traditional 1/4" flare. The same principle applies when using standard 1/4" flare equipment with 5/16" fittings, bearing in mind that traditional 1/4" flare equipment may not be safety pressure rated to the higher pressures used by R410A equipment.  Useful for using your manifold set for alternative applications and access to gas bottles. Please advise which version you require.
