About Us

We started Sandem Industries in 1970 in Midland Park, NJ and moved to our present location in Butler, NJ in 1980.

From the very beginning our goal was to provide premier quality seals and customer service to the Aerospace Industry.

Over the last 48 years we have evolved into one of the major seal suppliers to the semicon, valve, pump and fluid power industries just to name a few.

We have gathered numerous awards such as "Supplier of the Year" for Curtiss Wright Corp and Seal Technology Center for Parker Seal Company.

Since the year 2000 we have been fully certified to both AS9120 and ISO 9001:2015.

As a stocking distributor for Parker EMG Group we pride ourself on our large inventory of seals for all industries available for delivery the day you call.

Our premier engineering staff have over 100 years seal design experience between them.
