butterfly screw for gypsum board

  • Advantages:
    – Very good fitting stability avoiding pop-out of the seal
    – Modern lip design provides low radial forces
    – Superior radial stiffness, especially for very large diameters
    – Cost effective for expensive elastomer materials
    – Suitable for use in combination with axial seal

  • Oil Seals

  • Similar to the housing surface stop technique, this method uses a stop at the machined housing face to set the seal depth. It is typically used in housings with flat outer surfaces. Verifying the placement through visual inspection or with a feeler gauge ensures placement accuracy.
