301 static ring series

The 301 Static Ring Series is a precision fixed sealing component matched with various dynamic ring assemblies, designed for stable static friction pairing in industrial rotary sealing systems. Its core fitting part adopts pressure-free silicon carbide sealing rings of C-shaped step type. The stepped C-shaped structure optimizes contact surface stress distribution, avoids excessive squeezing force, suppresses friction heat generation and medium seepage under long-term continuous operation. Constructed with high-density sintered silicon carbide, these finished products are premium high and low temperature resistant sealing parts. They keep consistent hardness and sealing tightness amid sharp temperature fluctuations, without deformation or cracking. This series delivers stable high-pressure pump sealing and long-term reliable reaction vessel sealing performance, widely applied in chemical, pharmaceutical, petrochemical and wastewater facilities carrying corrosive, granular and volatile…
