The charts outline the system of Part Numbers. Each position in the Part Number provides information on the product's specifications or properties. Spaces designated "N" in this list are filled with a number or letter code explained at below. We can supply customers with configurations other than those listed (e.g., multiple feedthroughs mounted on the same flange). Please call for price and delivery on custom configurations.
