Manufactured from Viton® Fluoroelastomer with a 75-durometer hardness, these face seal O-rings offer superior resistance to heat, oils, fuels, hydraulic fluids, and a wide range of chemicals. Viton® is well-known for maintaining elasticity and sealing integrity even when exposed to sustained high temperatures, making these O-rings an excellent choice for applications where standard Buna-N materials may prematurely degrade.
The ORFS sealing method isolates the sealing surface from thread distortion and vibration, ensuring consistent compression across the O-ring face. When paired with Viton® material properties, the FS4000-V series delivers exceptional sealing reliability in systems subject to thermal cycling, pressure fluctuations, and chemical exposure.
