O-Rings for the HP/Agilent can be purcased directly from Agilent but they can be rather expensive. Now that the HP 5972 and HP 5971 is so old, finding the right o-rings can be problematic.
Here is a list of compatible orings.
We put together a kit but if you want to buy the o-rings individually here is a list of common O-rings found in the HP 5971 and 5972 GCMS system. Go to http://www.mcmaster.com/#o-rings click on brown viton fluoroelastomer o-Rings.
Through out the system you will find the KF-25 flange connection. This for the 5971 transfer line, the calibration valve and the rough pump connections. Buy the V320.
The large o-ring for the HP 5971 diff pump to manifold seal is the KF-50 seal. Buy the V330.
The small o-ring for the "tee" that attaches the rough pump hose to the diff pump is the KF-10. Buy the V312.
The small o-ring to attach to the small vacuum pump (typically the Edwards 1.5) is the KF-16. Buy the V314.
The oring that seals the 3/4" Ion gauge tube in most of the mass spec systems is the same. Buy the V116.
For the HP 5972 manifold o-ring, contact us directly. We have them in stock.
Hope this helps.
