Fit tungsten carbide seat to main body so that tungsten carbide ball can be fitted on tapered
side. Do not forget to fit packing.
Wrong assembling can cause wrong movement of pointer of pressure gauge due to leakage
from seat, failing performance.
Pay attention to tightening torque when fitting joint (ref.1).
Too much tightening can damage main body.
Tightening torque of joint 14.7 N-m
When fitting joint, pay attention that tungsten carbide ball does not slip out of the seat.
