For new IR-A series regulators, select option “H” (With hexagon panel nut (for panel mount)).
(e.g., IR1000-01H-A) The hexagon panel nut is shipped together with the product but does not come assembled.

This is a legacy product, and replaced byAW20-01H-C-B

If option “H” is selected, a set nut will be included with the product (e.g., AR20-01GH-A).
The set nut can also be purchased as an individual part. Refer to the “Option/Part Nos.” section in the AR series catalog.
Note that the type with a bracket always includes a set nut.

Refer to the AR-A/AR-B/AR-D series catalog excerpt, which has been reproduced below.
The part number of the standard AR20 to AR60 round type pressure gauge is “G36-10-01,” or “G46-10-01”(for the R thread type).
For example, the part number of the AR30-03BG-A pressure gauge is “G36-10-01.”

Refer to the AR-A/AR-B/AR-D series catalog excerpt, which has been reproduced below.
The part numbers of standard AR20 to AR60 round type pressure gauges are “G36-10-01” and “G46-10-01”(for the R thread type).
For example, the part number of the AR30-03BG-A pressure gauge is “G36-10-01.”

Do not use the spacer (with a bracket) of the AC series unit for high-pressure specification (special order part number suffix “-X425”) products.
When assembling high-pressure special order products, AF20 to 60-*-A-X425 and AR20 to 60-*-B-X425, prepare a nipple for installation.
