How to Order

Select the tube size from the table and specify the part number shown for the desired material (C30 or C98), replacing the (L) and (X) with the required length in inches. If a fitting other than the standard thread is required, specify by adding the “option code” from the optional fitting table as a suffix to the part number.

Examples:
C98 716F-18-8S
C30 916F-18-8C
