Hydrapak Basic Of Measuring a Seal 

Alot to learn about seals and your capability - thank you.

At 2:38 you say the ID is 3.00" but earlier in the sample you show it is 2.5". I'm probably not understanding it correctly. Thank you for the concise info without head banging 'music'.

Thank you.

Thanks a lot

It is simple because I am a Wa agent in this field

Where's the future videos at?

Then you measure the cylindrical section of the catalog, not the lips, am I right? I have a seal just like that, it has the code 250-1.75-375 and it should be installed in a 1.75in Rod, how can I calculate the cavity diameter amd width where it will be installed?

Do you have a branch in California?, please advise

Hard to measure a bad seal.
