Two counters covering the I-66 and I-95 corridors
Both Capital Pressure Supply stores — 11900 Livingston Rd Ste 139 in Manassas and 10817 Courthouse Rd in Fredericksburg — carry fresh 12.5% SH with bulk fill while you wait, plus 5-gallon carboys and 55-gallon drums.
We sell 10,000+ gallons a month, so inventory turns constantly. Every delivery is tested at 12.5% and the batch date is posted at the fill station — ask and we'll show you.
