The Spa Depot customer service people were to identify the parts I needed and had them in stock.
Same as the old pump gasket. Perfect fit.
I made the wrong choice in Gasket size. I end up trimming it and it is working for what I need. The items were shipped quickly.
After going around town looking for this piece, I found Spa Depot had just what I needed. I ordered it and received the part within days. They are definitely going to be the first place I go for any spa products.
