Simple Set Screw Solution- Shrink Seal

Today’s suggestion: Shrink Seal the set screws on your cryogenic liquid cylinder pressure building and economizer regulators.

There has been a lot of emphasis in this post on the difference between flow and pressure. The primary focus of discussion has been to try and clarify the fact that higher pressure does not equate to higher flow. Point: Cranking up the pressure builder setting on your liquid oxygen, nitrogen or argon 4L-DOT liquid cylinders does little or nothing to provide higher flow and can cause a number of negatives……..

- Out of Balance Economizers,
- Broken PB Regulators,
- Excessive Venting and more.

Solution- Leave the set screw alone. The odds of this happening- It depends.

Make it harder to mess with the screw and you might find an ounce of prevention to be worth a pound of cure. Where necessary- Create consequences for tampering with pressure builders and you might deter even more tinkering.

Oh, and yes- West Cryogenics has been doing this for years and sells both shrink seal material and heat guns.
