Clean One-Touch Fitting For Blowing KP Series Common Specifications

Applicable Tube

Tube materials	PFA, polyolefin soft polyolefin, polyurethane
Tube outer diameter	ø4, ø6, ø8, ø10, ø12

Note 1: FEP, nylon, soft nylon and other non-clean specification tubes can be used, but performance in terms of cleanliness will be reduced.
Note 2: Because polyurethane is a soft material, the tube may break when inserting. Hold the tube at its base and insert securely so that it reaches the back.

Specifications

Cleanliness class (ISO class)	Class 3 ^{Note 1:}
Usable fluids	Air, nitrogen gas, water, deionized water (pure water) ^{Note 2:}
Maximum operating pressure (20°C)	1 MPa ^{Note 3:}
Operating vacuum pressure	-100 kPa {10 Torr}
Guaranteed proof pressure (20°C)	3 MPa
Ambient temperature and working fluid temperature	-20°C to 80°C
Thread	JIS B0203 (tapered thread for pipes/tubes)

Note 1: See the "Particle emissions grade classifications" below.
Note 2: Make sure the surge pressure stays below the maximum operating pressure.
Note 3: The maximum operating pressure is the value at 20°C. For other temperatures, see "Relationship between operating temperature and maximum operating pressure" below.
Note 4: It is not completely airtight, so please avoid use in leak testers, etc., where a vacuum is maintained.
