Clean One-Touch Fitting For Blowing KP Series Common Specifications (Reference)

Applicable Tube

Tube material	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 pipe thread)

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: Do not use with a leak tester or for other forms of vacuum retention as they are not guaranteed for zero leakage.

Usage Precautions

The KP Series is composed of dedicated one-touch fittings for clean blow and cleaning lines.
Seal material used: Since the durability of EPDM degrades when exposed to mineral oils, it is not suitable for general pneumatic equipment piping.
