GTS Thread Sealant Paste

NOVUS GRAFOIL® GTS® Thread Sealant Paste is part of our portfolio of Gasket and Sealing products.

The GRAFOIL® product consists of a high purity paste made from a combination of nuclear grade graphite and a nuclear quality petroleum-based carrier. It has the inherent characteristics needed for long life performance, even under the most severe conditions.

Because of its resistance to heat and corrosion, GRAFOIL® GTS® Thread Sealant paste provides an effective seal for long periods of time, and will outperform conventional thread sealants in high temperature applications.

Features and Benefits:

  • Made to seal small diameter, close tolerance threaded pipe joints in critical applications
  • Meets many nuclear specifications due to its purity and thermal stability
  • Outperforms conventional thread sealants in high temperature applications
  • Also effective as a bolt lubricant or antisieze compound.
Each lot of GRAFOIL® GTS Thread Sealant is packaged in 125 gm nuclear grade polyethylene ‘squeezable tubes’ to protect against contamination.
