Vee Packing Set, 2.50 Inch OD, 2.00 Inch ID, 0.88 Inch Height

Six vees puts this set at the top of the pressure range, rated from 0 to 10,000 PSI. Sets with fewer vees are rated lower, four vees tops out at 3,000 PSI and five vees handles up to 5,000 PSI. So yes, the six-vee configuration is what gets you to that full 10,000 PSI rating.

It can handle pressure from 0 to 3000 PSI when using 4 vees, 0 to 5000 PSI with 5 vees, and 0 to 10,000 PSI when using 6 vees.

Fit comes down to the dimensions. This set is 2.00 inch ID and 2.50 inch OD, with about 0.88 inch height, so it matches a 2 inch inside diameter requirement and a 2.50 inch outside diameter housing.
