O-Ring: 20" ID x 20-3/8" OD, 3/16" Thick, Dash 389, Viton MPN:ZMSCV70389

A packing seal is designed to prevent leakage and absorb changes in dimensions during movement, which can be essential components of pumps for ensuring the durability of this product's construction using graphite which possesses superior corrosion resistance properties allowing it to work within harsh environments and remains strong under pressures exerted hence suitable for industries handling chemicals, acids or high temperatures. Additionally, being able to compress makes them ideal as a means of sealing where clearance between mating surfaces isn't completely matched up or changes while providing an environmentally sound solution due to its recyclability without damaging the environment; and most importantly it has easy installation allowing pump operators save on time hence efficient. Finally, due to graphite nature this product can be easily fitted within various seals providing an excellent repair solution for seals which wear out during pump operation in diverse industries like construction water treatment among others where pumps are commonplace.
