Model
Specifi cations
Flow-rate and Sonic Conductance
New-stand male threads for piping that reduces the screw-in time by 1/3.
Shape of Uni thread ridge
Use of the chamfered surface of the female
thread as the seat surface and adoption of
gaskets made by laminating NBR on both
surfaces of stainless steel plates achieve
secure sealing regardless of the difference
of diameters due to the female thread type,
deviations due to the tolerance, or the size
of the chamfered corner.
(Any standard chamfered female thread
can be used.)
A ridge shape has been
created as a Uni thread
for common applications
for Rc, G, NPT and NPTF.
The male thread for piping
drastically cuts piping
man-hours.
Caution
Be sure to read this before handling.
Refer to the back cover for Safety In-
structions. For Flow Control Equip-
ment Precautions, refer to “Handling
Precautions for SMC Products” and
