Clean One-Touch Fitting For Drive System Air Piping, KPQ/KPG Series Common Specifications (Reference)

Applicable Tube

Tube material	PFA, polyurethane
Tube outer diameter	ø4, ø6, ø8, ø10, ø12

FEP, nylon, soft nylon and other non-clean specification tubes can be used, but performance in terms of cleanliness will be reduced.

Specifications

Cleanliness class (ISO class)	Class 3 ^{Note 1:}
Usable fluids	Air
Maximum operating pressure (20°C)	1 MPa ^{Note 2:}
Operating vacuum pressure	-100 kPa
Guaranteed proof pressure (20°C)	3 MPa
Ambient temperature and working fluid temperature	-5°C to 60°C
Thread	JIS B0203 (tapered pipe thread)
Oil or grease used	Fluorinated grease

Note 1: See the "Particle emissions classifications" below. The internal sealing parts are coated in fluorine grease and so are outside the scope of the grading.
Note 2: The maximum operating pressure is the value at 20°C. For other temperatures, see "Relationship between operating temperature and maximum operating pressure."
Note 3: Do not use with a leak tester or for other forms of vacuum retention as they are not guaranteed for zero leakage.
