Rubber Tank Strips with Punched Holes

EPDM, CR, NBR fuel tank seal strips are produced using microwave curing process. The strips feature strong plasticity, good elasticity, and resistance to compression, chemicals, aging, and ozone.


Fuel tank strap rubber seal gaskets come in 1.77″ width rubber strips with punched holes at regular intervals. The rubber tank strips are used as liquid tank gas sealants for prevention of metal-to-metal wear between the straps and gas tank due to vibrations. They are used in various industries, including food, chemical, and oil storage.


Product Features | Thickness, Hole Shape, Spacing, Materials 

Punching thickness is between 1/16~1/14”. This process can be applied to thinner and thicker materials depending on client’s requirements.


Standard and custom oval, square, or alternate hole shapes are available. Slit-to-width rubber rolls without any holes are available as well and vary between 25 and 300 foot lengths.


Dimensional tolerances run around +/-.015 inches for key dimensions: width and hole diameter.
