High-Performance MRO Solutions

Gasket Maker
GorillaPro gasket maker eliminates the need for pre-cut or compression gaskets. Used to fill the voids between metal flanges, it creates a seal that protects the joint against corrosion. GorillaPro gasket maker is resistant to common oils and gasses

  • Fills all surface imperfections
  • Withstands high temperatures and pressures
  • Eliminates micromovement and slipping
  • Won’t shrink, crack, or relax
  • For use on rigid iron, aluminum, and steel flanged surfaces

Pipe Sealant* 
In addition to sealing fine threads, GorillaPro pipe sealants can also seal pipe fittings thanks to their ability to withstand most chemicals. These sealants provide a complete seal between threads, offering many advantages over traditional sealing methods like PTFE tape or hemp.

  • Fills space between threaded parts
  • Instant, low-pressure seal
  • Prevents fluid and gas leaks
  • Withstands most common chemicals
  • Ideal for applications such as pipe fittings andhydraulic hoses
Product Attributes
  • Tight Tolerance: Seals close-fitting joints between rigid metal assemblies
  • Secure: Best for differential cases, transmissions, and oil pans
  • Durale: Superior chemical and heat resistance while maintaining flexibility for proper gasketing

Applications & Uses

Compatible Substrates & Surfaces
Cure Method
Application Instruction

Surfaces to be bonded should be clean, dry and free of grease. Product should be applied manually as a continuous bead or by screen printing to one surface of the flanges. The product performs best in thin bond gaps. Very large gaps may create voids that will affect the cure speed and overall strength. Good contact is essential. An adequate bond develops in 15 to 45 minutes and maximum strength is attained in 24 hours. This product is not recommended for use in pure oxygen environments and/or oxygen-rich systems and should not be slected as a sealant for chlorine or other strong oxidizing materials. This product is not designed for plastics, particularly thermoplastics where stress cracking of the plastic could result. It is recommended to confirm compatibility of the product with all substrates prior to use.

Curing Performance
The rate of cure will depend on environmental conditions and the substrates used. The gap of the bond line will affect set speed. Smaller gaps tend to increase set speed. Activators may be applied to further improve set speed, but may also impair overall adhesive performance.
