Due to descript of tube length are not same by different customer,

In order to avoid the make a mistake and exactly descript the customer message turn to our company message, we make a unify form for test.

Visual tube length: outside of tube length 

Total tube length: Mean net tube length, need to pull out measurement the tube length

FBOG tube length: mean the tube length is from the gasket 

 

For example

If get the message of total tube length, Visual tube length=net tube length-9mm

If get the message of FBOG, Visual tube length=FBOG-63mm-9mm+2mm

If get the message of bottle length, Visual tube length=Bottle length -63mm-9mm+2mm
