We have been using DME expansion joints for many years in our O.E.M. applications and find them to be very reliable. Some of our customers needed to replace their old expansion joints in a timely manner and DME has fulfilled their needs with their "expedited service" option. This has been very helpful over the years. It's very hard these days to find a vendor that you can depend on and I am happy to say that DME is a dependable vendor.
