What's the pressure rating on this set, and does the number of vee rings actually change it?
Answer by: Customer Support on Dec 20, 2025, 1:59 PM
Yeah, the number of vees makes a real difference. Four vees gets you up to 3,000 PSI, five vees bumps that to 5,000, and if you go with six vees you're looking at a 10,000 PSI ceiling. The set itself runs a 4.00 inch ID and 4.50 inch OD, so as long as those dimensions match your bore and rod, you just pick the vee count based on what your system's pushing.

got a cylinder that takes a 4 inch rod, are these sizes the rod size or the groove size?
Answer by: Customer Support on Oct 5, 2025, 6:59 AM
For this vee packing set, the key fit numbers are the 4.00 inch ID and 4.50 inch OD. The ID is the inside diameter of the packing stack and the OD is the outside diameter once it is assembled.

What's the deal with the pressure these can handle? I'm running some pretty high pressure stuff.
Answer by: Customer Support on Feb 27, 2026, 11:11 AM
The pressure rating depends on how many vees you stack in the set. You're looking at anywhere from 0 to 3000 PSI with four vees, up to 0 to 5000 PSI with five vees, and even 0 to 10,000 PSI if you go with six.
