Ralph Paoli about FSS:
"FSS is a provider of services and engineered sealing solutions to the international infrastructure, manufacturing and process industries. The way we see ourselves is creating value for clients through the application of our sealing technology. More and more we are working in an alliance and partnership basis with our clients, moving away from the traditional relationship and traditional forms of contract. We are very much a design-led business."


A NOTE ABOUT OUR PRICING - We have included current pricing on as many products as possible, some are subject to change without notice. Our pricing is competitively aggressive, we have 2 price levels. You can choose from our complete plant standardization pricing program or our web site pricing.
Some companies do not purchase our products but use our prices to negotiate better deals from their current suppliers. When this happens, almost every supplier will drop their prices to match ours.
Hmmmm, did these companies ever ask their suppliers why they were gouging them in the first place?  Or maybe ask them for a credit for past purchases? Or ask them, "why didn't you give us your best price right away?"
You can imagine how I feel about this - all we ask is - throw us a bone once in a while and see what price and service is really about.
