Query Is Excluding Needed Information

I have created a query showing locations of a company's facilities, and product groups associated with that facility. Unfortunately the the products groups are located in one column and, if the facility produces more than one product, the product group is divided by a |, as shown below:
CABLE TRAY SECTION [05CT]|STEEL CONDUIT AND ELECTRICAL METALLIC TUBING SECTION [05RN]
In my query, I only want to show the product code, which I resolved by creating another table and associating the code with the product group. However, this query will exclude those plants that produce multiple products. How can I show just the product codes for all the facilities, including those with multiple product groups?

In otherwords, I would like the above example to look like this: 05CT|05RN (or something similar to this).
