Selecting the right drum plug gasket is important to maintain the product integrity of your drum and to keep everything leak tight. CFDPLAS offers a full line of gaskets in a variety of material and sizes.
Gaskets come in 2", 1 1/2" and 3/4" NPS sizes. "NPS" is the thread type and it stands for "National Pipe Straight". They are straight with a 60° included angle.
There are 2 types of rubber constructions for gaskets:
Sponge rubber gaskets - Made from rubber compounds that contain ingredients that "blow" the spongy cellular structure as the rubber cures into either an open cell or closed cell
Dense rubber gaskets - Made from solid rubber with no cellular structure
There are various types of rubber gaskets out in the market and right here at CFDPLAS and each are more compatible with certain products:
Styrene Butadiene (SBR) gaskets: The oldest type of gasket rubber with good aging, abrasion, and heat resistance and the highest volume general purpose, common synthetic rubber. Best for general purpose storage of drums.
Ethylene-Propylene (EPDM) gaskets: The newest generation of gasket rubber that has become quite so common due to its extreme versatility in applications. Best for when storing drums in either hot or cold environments or if working with hydraulic fluids that are corrosive and dangerous when exposed to human skin.
Viton gaskets: Excellent resistance to oils, acids, fungal growth, ozone, flammables, high temperatures, petroleum, chemicals, and weather. Best for when storing aggressive products like fuels in your drums.
