Serviced last year. Will include a new tank neck O-ring. $25 a piece that includes shipping to CONUS.

Are these threaded 3/4-inch NPSM or 7/8-inch UNF?

They appear (to me) to be 3/4npsm due to the flats for applying a wrench to tighten. Pretty much every 7/8unf valve I've handled does not have the flats for a wrench where the valve meets the neck.

I can't tell 100% from this picture but it seems this 7/8" UNF threaded valve has a flat area for a wrench, but it could just be an illusion from the angle the photo was taken:

The XS 300 BAR DIN valve with 7/8 UNF neck thread is for Air Service Only. This unique valve is designed for use with smaller neck diameter High Pressure cylinders. The valve is rated for 4350 PSI service pressure.
