It is suitable for anti-revolve cement rubber plug and anti-transformation floating hoop and floating shoes. The shell is made of nitrile rubber material and wear-resistant, and the frame anti-turning flower plate is made of phenolic resin high temperature and high pressure compression. It has excellent anti-torque performance and is easy to drill.
