Face seal adopted for threading.
Original thread construction which allows for the use of piping taper female threads (Rc, NPT)
Allows for neat and
compact piping
without protruding
threads
<Application example>
Mounted to a blow gun
(VMG11W-02-01)
After hand-tightening After hand-tighteningAfter tool-tightening After tool-tightening
Re-piping is possible.
Sealant tape is necessary because sealant be-
comes separated with repeated installation.
Repeated re-piping of up to 6 to 10 times is possi-
ble due to use of elastic sealant on seating.
Prevention of sealant residue/protrusion
The current sealant type leaves residue and protrudes out
from the threading when installing, making it necessary to
clear away the residue using an air blower or similar.
However, no residue is created when using a face seal.

1 The surge pressure must be under the maximum operating pressure.
2 Deionized water is not recommended for use as it may affect the material used in the fittings. In addition,
it is known to degrade the water quality.
3 Do not use the fittings with a leak tester or for vacuum retention because they are not guaranteed for zero
leakage.

Suitable for use with nylon and
urethane. Large retaining force.
The chuck provides secure retention and
the collet increases the holding force on
the tube.
Can be used for a wide range of
pressures from a low vacuum
up to a pressure of 1 MPa.
The use of a special profile ensures
sealing and reduces resistance when
the tube is inserted.
Requires little force for
removal.
Releases the chuck collet to remove
the tube as well as to prevent the
chuck from biting too deeply into the
tubing.
Effective when piping in a
confined space.
Body part rotates allowing for
positioning.

For Pneumatic Piping/Fittings & Tubing
Prior to Use
Fittings with Sealant
Seal material (fluororesin) is coated on the thread part with the proper thickness and range, that reduces the piping work, such as coating the seal
on the thread.
Female Thread Conditions Applicable to Face Seal
1. Surface roughness of bearing surface: Rz 25 or less
2. Chamfer dimension: øD1, Seal bearing surface diameter: øD2 (Refer to the table below.)
3. Female thread inclination angle: 1 or less
4. Counterbore diameter when the female thread is counterbored.: øD3
· Models with width across flats: Body width across flats x 1.1 or more
· Models other than hexagon (Hexagon socket head male connector etc.): Body dimensions + 0.2 mm or more
The width across flats and the body dimensions differ depending on the model even when the same thread size is used.
Refer to the dimensions in the catalog.
5. If oil content or sealant is sticking to the female thread, this may cause damage of the product. Remove it before piping.
Table 1
Precautions
For products that do not satisfy the female thread conditions shown above and the piping with a piping pitch narrower than the product dimension,
use the current sealant type.
The rubber parts of the face seal cannot be replaced.
The rubber parts of the face seal may fall off by the air blow and they cannot be mounted again. Be careful not to perform the air blow.
