Note 1: øD indicates the maximum diameter.
| 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.
| 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.
