Dimensions are in inches. Weights are in pounds.


rf.. In Pressure Classes 150 and 300, the height of raised face is approximately 1/16 inch. In Pressure Classes above, the height of rf is approximately 1/4 inch.


Material.. Studding Outlets are most commonly provided in SA-105. They can also be made from a full range of stainless and alloy materials.

Thickness.. The standard thickness shown above for all studding outlets is the minimum required per ASME Section VIII Division I Paragraph UG-43(d) for thread engagement and an ID mount. It is important to note that each individual application should be analyzed for proper thickness.
