Avseal®

Engineered for both low-pressure and high-pressure hole sealing applications.

The Avseal sealing plug has been engineered for both high and low pressure hole sealing applications making the Avseal sealing plug unique.

The rapidly installed two-piece sealing plug improves quality and safety in demanding applications while simplifying hole preparation and installation, reducing assembly costs.

Key features and benefits

  • Fully annealed sleeve - high sealing performance
  • Hole fill capacity - improved seal and wider hole tolerance
  • Larger hole tolerance - simplified hole alignment when automated placing is required
  • Seal by compression of the sleeve - improves sealing with great hole fill capability over a wider hole tolerance
  • Internal lock - flat nose tip and ease of use
  • Improved stem retention - increased vibration resistance
  • No locking ring formed by nose tip - standard equipment reduces preventative maintenance
  • Low force special version - can be used in thin wall applications
  • Tapered sleeve and stem - ease of entry into application and nose tips, suited to automated systems
  • Shorter placed length, blind side protrusion reduced - use in restricted space or thin wall
  • Can be easily modified - can suit specific applications
  • Ease of placing with standard tooling - quality of seal is not operator dependant

Avseal sealing plugSpecifications
