Hi Jason:

Looking through the DELTAplus XL service manual with a picture of the
Analyzer System the small turbo pump would be the differential pumping
system pump.  On the Analyzer System diagram the seal is identified as item
no. 10 (same as the flight tube connection to the source)edge seal DN63,
aluminum p/n 0693220.

I hope this information helps.  My understanding is that in a pinch the seal
can be used more than once as long as it hasn't been tightened too tight the
last time.

Subject: DeltaPlus XL turbo question

Hi All
Can anyone confirm the seal between a DeltaPlus XL and the smaller 
turbo pump (Pheiffer TMH064) is the viton seal as written in my 
Pheiffer manual?    I have no information in any of the Thermo manuals. 
  The pump just died and I have not taken it off and don't want to until 
the exchange one arrives and don't want to be caught without the 
correct gasket.  Thanks Jason
