＊ 1 We will select a proper material for your application.
＊ 2 SUS304 is the standard material for the following specifications:

Note: An R3/8×Rc1/2 adapter is attached for Rc1/2 or larger connection.

• When the connection standard is flange.
• W hen the flow direction is Bottom to Top and the processconnection is Rc or NPT1/2" or larger.
SUS316 may be used instead of SUS304 due to production
reasons.
ASTM or AISI materials equivalent to JIS materials may be used dueto production reasons.

* Specification is subject to change without notice.
