Handling of Barb Fittings and Nut Fittings
Caution
1. When using a nut fitting, insert the hose all the way to the
end and securely tighten it with the nut. When the inser-
tion of the hose or the tightening of the nut are not
sufficient, the hose may slip out.
2. Disconnection may occur depending on the material or
the O.D. accuracy of the hose; therefore be sure to
confirm the applicability of the hose.
3. Prepare a hose band separately when using a barb fitting.
If the hose band is not used, the hose may come off.
1. Tightening of the fittings with a sealant
Tighten fittings with sealant using the proper tightening
torques in the table below. As a rule, they should be
tightened 2 to 3 turns with a tool after first tightening by
hand.
