Petrochemical, Railcar and Transport Truck

Hendee Enterprises is a leader in the manufacture of seal and filter products.  We developed our seals and filters with the petrochemical, railcar and transport truck industries in mind.  Our seals are a barrier against moisture and contaminants.  We manufacture seals for the top and bottom of railcars and transport trucks.  The products are easy to use and install.  

The filters made by Hendee protect against contaminants by filtering incoming air as the products are vacuum unloaded.  Using these filters during transport and unloading will extend control over product purity.  Our filters are for the top and bottom of the railcar and transport truck.  

The majority of products manufactured by Hendee are meant to be a single use item to avoid any cross contamination or equipment damage.  The products are easy to use and install.
