You can replace them with any type of seal given the same dimensions.

The cylinders gland seals now weep at low psi only and will hold 4000 psi for two (2) days before any leakdown. But I would like to be able to upgrade.

You may find that the replacement seals do the same thing. Certain style seals only come in certain dimensions. If you can get a U-style urethane seal with a loader ring, you can solve your low pressure weeping. Loaded seals have a type of o-ring inside the U that holds the seal against the sealing surfaces at low pressure eliminating weeping or cylinder drift. Some cylinders need this, others do not. There are many variables that determine this. If they are the Vee style seals, you could mix in a urethane seal with your Vee pack to improve low pressure sealing. I like to use 1 urethane and 3 fabric. In a set of 5, you can use 2 urethane.
Personally, if this is all that's wrong with your 1950 cylinders, and this is just an inconvenience, I would not touch them. After resealing, you may not see an improvement. If someone brought these cylinders to my shop with your circumstances, I could not guarantee an improvement.
This catalog should help.
- Hercules. Look up VR style seals. I think that's what you have. Believe it or not, this style seal is still used in new equipment. Measuring is easy. They are very inexpensive so do yourself a favor and order extra.
Need any help, just ask.
