Piping for Air Pressure Supply and Vacuum Pressure Supply
(1) Preparation before piping
Before piping, perform air blow (flushing) or cleaning to remove any cutting chips, cutting oil,
dust, etc. from the piping.
(2) Wrapping of pipe tape
When installing piping or a tube fitting into a port, prevent cutting
chips and sealant material from getting inside the product.
If a sealant tape is used, leave 1 thread exposed at the end of threads.
(3) When connecting tubing, consider factors such as changes in the tubing length due to
pressure, and allow a sufficient margin.
Otherwise, it can damage the fitting and cause the tube to come off. Refer to Fittings & Tubing
Precautions from 1 to 4 shown in Best Pneumatics 6 on SMC’s website (URL
) for the recommended piping conditions.

Piping to the Exhaust Port, Vacuum Port Adapter
Piping to the Exhaust Port
When mounting or removing
the piping to or from
the exhaust
port, hold the exhaust
block with
a wrench (across
the flats 36).
Recommended tightening torque:20 to 25 N·m
The product may break, if it is held
by hand.
Piping to the Vacuum Port Adapter
When mounting or removing
the fitting,
etc. to or from the
vacuum port adapter,
hold the
vacuum port adapter with a wrench
(across the flats 19).
Recommended tightening torque:3 to 5 N·m
The product may break, if it is held
by hand.
When piping is connected to the exhaust port block and vacuum port adapter, pay attention
that no twisting, tensile, moment loads, vibration or impact should be applied to the piping.
This can cause displacement or damage of the port.
