DSZH straight male/female SAE unions 5/8-3/4" are used in HVAC and refrigeration systems to connect copper tubing or hoses with SAE flare fittings.

The unions feature SAE 45-degree flare connections and are rated for use with R410A and other common refrigerants. Maximum working pressure is 600 psi.
