GWPP Series - Gum Silicone Weld-Nut Pull Plugs

  • Made from Gum Silicone for Higher Tensile Strength and Increased Durability
  • Dimpled Washer Conforms to Irregular Surfaces and Masks Off Countersinks and Lead-In Threads
  • Pull-Tab Allows for a Larger Diameter Plug to be Pulled into Place for a Tight Seal
  • High Temperature Silicone Formulation Ensures Stability at Elevated Temperatures
  • Designed to Pull Through Same Direction as Applied to Create a Clean Break from any Surface After Coating

Product Description:

Our Gum Weld-Nut Pull Plug (GWPP) product line is a pull plug line specifically engineered to tackle the tough requirements of masking off the lead-in chamfer of threaded applications. Made of our special formulation of high temperature silicone, Weld-Nut Pull Plugs exhibit remarkable flexibility, while maintaining reusability and reliability during masking.

Typical Applications:

  • Used to plug weld-nuts during welding. Plug can remain in place for subsequent coating process. Other applications include protecting countersink and leading threads; especially where a tight seal is required.

Helpful Hint:

  • When plugging a hole, make sure that the major diameter of the plug is larger than the diameter of the hole being plugged by at least 10%.
  • Use Gum Weld-Nut Pull Plugs (GWPP) in applications where countersinks or lead-in chamfers are necessary masking areas.
  • Keep in mind any interference issues that will be created by the Pull-Tab being completely exposed after plug is inserted.
