Tubing Ordering Suggestions
Tubing for use with Parker instrument fittings must be carefully ordered to insure adequate quality for good performance. Each
purchase order must specify the material nominal outside diameter, and wall thickness. Ordering to ASTM specifications
insures that the tubing will be dimensionally, physically, and chemically within strict limits. Also, more stringent requirements
may be added by the user. All tubing should be ordered free of scratches and suitable for bending.
A purchase order meeting the above criteria would read as follows:
“1/2 x .049 316 stainless steel, seamless, or welded and redrawn per ASTM A-249. Fully annealed, 80 Rb or less.
Must be suitable for bending; surface scratches, and imperfections (incomplete weld seams) are not permissible.”
Table 9 lists specific ordering information for each material.
