When it comes to selecting seal materials for stainless push in fittings, it’s important to consider factors such as chemical compatibility, temperature resistance, and overall performance. The seal materials play a critical role in ensuring a reliable and leak-free connection between the fittings and the tubing.
Our stainless steel push to connect fittings are fitted with Viton seals. Viton is a brand of synthetic rubber known for its excellent resistance to a wide range of chemicals, high temperatures, and extreme environments. It is a type of fluoroelastomer, which means it contains fluorine atoms in its molecular structure.
Some of the advantages and characteristics of Viton are:
Chemical Resistance: Viton exhibits exceptional resistance to a wide variety of chemicals, including acids, fuels, oils, solvents, and many corrosive substances. This makes it an ideal material for applications where exposure to aggressive chemicals is common.
Temperature Resistance: Viton can withstand high temperatures, typically ranging from -25°C to 200°C or even higher, depending on the specific grade and formulation. It retains its flexibility and sealing properties at both low and high temperatures.
Excellent Compression Set Resistance: Viton maintains its shape and elasticity over time, even when subjected to repeated compression and decompression. This characteristic is crucial for gaskets and seals that need to maintain a reliable seal over extended periods.
Weather and UV Resistance: Viton is resistant to weathering, ozone, and ultraviolet (UV) radiation. This makes it suitable for outdoor applications where exposure to sunlight and environmental conditions is a concern.
Low Gas Permeability: Viton has low gas permeability, making it an excellent choice for sealing applications where preventing the escape or ingress of gases or fluids is critical.
Flexibility: Viton remains flexible over a wide temperature range, allowing it to adapt to various sealing and gasketing applications.
Longevity: Viton seals and gaskets are known for their durability and long service life, reducing maintenance and replacement costs.
