    Why Choose YOSON PTFE O-RING

    Corrosion Resistance
    Corrosion Resistance

    PTFE is the best possible material to choose in applications where caustic or corrosive chemicals are present. PTFE O-ring is resistant to nearly all chemical agents. Thus, it is ideal for most demanding utilization.

    Longevity

    Extensive service durations in hazardous situations have occurred in a variety of applications. In this scenario, PTFE can be of great help. The PTFE chemical resistance feature tops that of typical elastomers.

    Wide Temperature Range
    Wide Temperature Range

    Among other elastomer options on the market, PTFE can be suitable for applications with temperatures ranging from -325°F to +500°F. As a result, PTFE is an excellent option for cryogenics treatments and more.

    Chemical Resistance
    Chemical Resistance

    Carbon-fluorine bonds are the main component of PTFE, which is the strongest single bond in organic chemistry. Hence, it is chemically stable and highly weatherable and has resistance to water and abrasion.

    How PTFE O-Ring Works

    Like typical O-rings, PTFE-made ones seal the mating surface of two components. They are applicable for pipes, hoses, and more fluid-carrying passages. Because the O-rings are ring-shaped, they can slip on cylindrical flows easily. Various usages, specifically the hoses, feature a groove designed for PTFE O-rings application. This groove ensures the O-rings position.

    Moreover, the PTFE O-rings are designed with gas, heat, and water resistance, making them withstand pressure. They also characterized flexibility that expands to prevent media leakages. YOSON customizes precise O-ring measurements to suit your particular usages.

    PTFE O-Ring Benefits

    Compared to other O-rings, the Teflon-made ones provide more extreme heat resistance. They can handle a maximum of 350 degrees Fahrenheit without losing their performance. Also, the PTFE-made O-rings create minimal friction. Because PTFE materials feature softness and elasticity, they are ideal for liquid-carrying passages applications. 

    Consider also the additional advantages of PTFE O-rings:

    • UV-protected and ageless
    • Moisture-proof
    • Explosive decompression unsusceptible
    • Electric resistant and dielectric strength

    PTFE O-Ring Available Customization

    YOSON customizes O-rings from different materials that are in demand in seal markets. But we specialize in using virgin PTFE materials, which have limited sizes that adhere to AS568B standard numbers. We customize the following factors:

    • Accurate Sizing: We customize PTFE O-rings using machined sizes. Custom cross-section sizes are made-to-order for easy squeezing and compression adjustments.
    • Pressure Customization: A thicker cross-section is needed to enhance sealing performance in high-pressure conditions. While for low-pressure states, less than typical O-rings achieve application needs.
