SULFANILIC ACID Resistant O-Rings and Seals

Sulfanilic acid, also known as 4-aminobenzenesulfonic acid, is an organic compound used as a dye intermediate, a reagent, and a precursor in the synthesis of dyes, pharmaceuticals, and other organic compounds. It is also used as a corrosion inhibitor, a cleanser, and in the manufacture of photographic emulsions.

When rubber is exposed to sulfanilic acid, the acid can cause the rubber to become brittle and break apart. Additionally, the acid can corrode the metal components found in rubber seals, leading to further failures. Furthermore, sulfanilic acid can cause rubber to swell and soften, leading to decreased flexibility and seal integrity. Additionally, sulfanilic acid can cause the rubber to discolor or fade over time.


Fluorosilicone (FVMQ, FSIL)

Fluorosilicone o-rings are a hybrid of silicone and FKM resulting in great jet fuel resistance with high and low temperature performance. Also widely used in semiconductor Ashing equipment with strong resistance to oxygen plasma, FVMQ fluorosilicone o-rings also feature excellent flexibility, compression resistance, aging and sunlight resistance, and overall wide range of basic chemical resistance.
