*Note 1) Options B, G, H, M are not assembled and are supplied loose at the time of shipment.
*Note 2) Set nuts are included with the bracket.
*Note 3) Products AR20-B to AR40-B are not interchangeably mountable with previous products AR20 to AR40.
*Note 4) When the pressure gauge is attached, a 1.0 MPa will be fitted for standard (0.7‑MPa setting) type; 0.4 MPa for the 0.2‑MPa type (1.0‑MPa pressure gauge only for the AR10-A).
*Note 5) Pressure can be set higher than the specification pressure in some cases, but use with the pressure within the specified range.
*Note 6) Thread type: NPT. Under new Japanese measurement laws, this product is only available for sale outside of Japan (SI units are used in Japan). Round-type pressure gauge (with color zone): cannot be used in combination with M.
*Note 7) ○ is for thread types M5 and NPT only.
