Rated for pressures up to 10,000 PSI depending on configuration, this Vee Packing Set from Hercules Sealing Products is suited for hydraulic cylinder and rod sealing applications across a wide range of industrial equipment. The set measures 4.25 inches OD, 3.75 inches ID, and 1.00 inch in height, with construction consisting of fabric-reinforced rubber and urethane vee rings paired with nylon top and bottom adaptors.
The Vee Packing Set is designed to accommodate varying pressure requirements based on the number of vee rings used, four vees cover 0–3,000 PSI, five vees up to 5,000 PSI, and six vees up to 10,000 PSI. The temperature range spans -65°F to 220°F, making it suitable for both cold-start and elevated-temperature service conditions. Ordering codes indicate the quantity of each component type: top nylon adaptor, urethane vee rings, fabric vee rings, and bottom nylon adaptor, in that sequence.

What kinda pressure can I get outta this packin' set?

It depends on how many vee rings you stack in there. Four of 'em will handle up to 3,000 PSI, five will get you to 5,000 PSI, and if you use six, you're good for up to 10,000 PSI.

got a cylinder gland that measures 3.75 on the bore and about 4.25 on the outside. is this packing set the right size or am i readin it wrong

Fit is based on the set dimensions. This one is 3.75 inch ID, 4.25 inch OD, and 1.00 inch tall, so it matches those measurements if that is what your gland is set up for.

ordering code on this one got me a little turned around. if i need it rated for 5,000 PSI, how many vee rings am i looking at and how do i read that part number to make sure i order it right?

Five vees gets you up to 5,000 PSI with this set. The ordering code breaks down into four positions: the first number tells you how many top nylon adaptors are included (almost always 1), the second is the quantity of urethane vee rings, the third is fabric vee rings, and the fourth is the bottom nylon adaptor count (also usually 1). So if you're building a five-vee stack, your code would reflect one top adaptor, your split of urethane and fabric rings adding up to five total, and one bottom adaptor. Count the vee rings in the code and match that to your pressure requirement before you finalize the order.
