Specifications
- Usable fluids: Air
- Operating pressure range (Note 1): -100 kPa to +1 MPa
- Proof pressure: 3 MPa
- Ambient and fluid temperature: -5 to +60°C (no freezing)
- Threads: JIS B0203 (taper thread for piping), JIS B0205 (metric coarse thread), ANSI/ASMEB1.20.1 (NPT thread), JIS B0212 (Unified Fine Thread [UNF])
(Note 1) Do not use the fittings with a leak tester or for vacuum retention because they are not guaranteed for zero leakage. Also, when using in a vacuum, grease may enter the inside due to the nature of its construction.

Notes
- *1Ball bearings are used in the rotating parts, so please implement the tube piping in such a way as to avoid lateral load. If there is lateral load applied to ball bearings, then their life expectancy may be affected adversely. Using a flexible polyurethane tube is recommended when lateral load is applied.
- *2Do not use in an environment where it will be exposed to water. Contact with water will cause outflow of the lubricating oil used in the ball bearings, affecting rotating performance and equipment life-span.
- *3Fluorine grease is used on the rotating parts.
