1. Plug is inverted installation to reduce the operation torque.
2. Lubricated Oil is injected into the oil groove and a oil film will be between the body and the plug sealing face to achieve excellent seal performance and reduce the abrasion.
3. Suitable for applications with high temperatures.
4. Plug is overlaid with stellite or done with surface harden treatment to increase abrasion and corrosion resistance and prolong the service life.
