NSF S2 iconNonfoods Category Code Mark BLUE

LOX-8 Thread Sealant is oxygen compatible and is highly recommended where harsh chemicals such as chlorine or powerful oxidizers are present. It is the product of choice in applications where critical safety and resistance to aggressive chemicals are primary requirements. Providing superior performance as a sealant and anti-galling agent, LOX-8 withstands both extreme temperatures and high pressure.

It is specifically formulated for wet conditions, but can also be used in dry conditions. It is a high density sealant expressly designed for severe high-pressure applications.

  • Odorless, noncorrosive, waterproof, non-migrating, and nonflammable
  • Certified for oxygen service
  • NSF approved for use in food processing facilities.

Description

LOX-8 Thread Sealant chemistry is engineered for harsh-chemical situations where extreme acids or powerful oxidizers are used. It is a chemical-resistant sealant that prevents stainless steel galling, withstands high pressure, high temperatures, and cryogenic deep freeze temperatures. Oxygen-safe, waterproof, and versatile, it is both a sealing pipe thread compound and an anti-galling agent. Works great with oil-based systems, hydraulic oils, and fuels. LOX-8 is recommended for use as both a lubricant and as a sealant by The Chlorine Institute members. Safe to use with PVC threads as a plastic pipe joint sealant but be careful to not over tighten.

See the Technical Data Sheets for complete list of specifications, approvals, testing, compatible liquids, gases, and aggressive chemicals.

KEY BENEFITS

  • Formulated for wet conditions and dry applications. High-density, inert thread sealant
  • Remains stable up to +287°C (+550°F). It is nonflammable and nontoxic.
  • Oxygen-safe (gaseous & liquid)
  • Not affected by harsh chemicals such as chlorines, permanganates, hypochlorites or powerful oxidizers
  • Allows you to standardize on one sealant, replacing all the pipe sealants in your tool box or factory. Eliminates plumbing errors, standardizes inventory and practices.
  • Anti-galling, anti-seize, anti-corrosive
  • Non-migrating, non-hardening sealant
  • Oxygen-approved by The German Federal Institute for Materials Testing (BAM) and ASTM G72-82 and ASTM G86 (NASA)
  • Praxair GS-38 approvedNSF S2 icon
  • NSF-approved for use in food processing facilities
  • NLGI 2 grease and lubricant

Frequently Asked Questions

LOX-8 Thread Sealant is chemically inert and compatible with a wide range of aggressive chemicals and environments, including strong bases such as sodium hydroxide and potassium hydroxide. For specific compatibility questions, contact our engineering team with details about your application.

Yes. LOX-8 Thread Sealant is designed for demanding environments and is compatible with many corrosive and aggressive chemicals, including concentrated sulfuric acid and strong bases. For specialized applications, we recommend confirming compatibility with our engineering team.

Yes. LOX-8 Thread Sealant can be used with threaded plastic piping and fittings, including PVC and CPVC. Compatibility should be confirmed based on both the piping material and the chemicals being used.

LOX-8 Thread Sealant is stable from cryogenic temperatures up to +287°C (+550°F). It can also be used in below-freezing applications, including temperatures as low as -30°C.

LOX-8 Thread Sealant is designed to provide long-term sealing performance when properly applied and torqued. While there is no specific service-life rating, LOX-8 seals have been observed to remain effective in equipment after more than 10 years of service.

Storage life and service life are different. Separation that may occur during extended storage does not affect performance once the product has been properly applied and the connection has been torqued.

The main difference is consistency. LOX-8 Thread Sealant is thicker and is typically used to seal threaded pipe joints, while LOX-8 Lubricant is thinner and is generally used to lubricate bearings and other surfaces where severe oxidizers are present.

Both products are chemically inert, oxygen-safe, anti-galling, anti-seize, and anti-corrosive, and both are stable from cryogenic temperatures to +287°C (+550°F).

Yes. LOX-8 products are oxygen-safe and designed for demanding applications. LOX-8 Thread Sealant can be used to seal threaded connections in oxygen systems, while LOX-8 Lubricant can be used where lubrication is needed in the presence of severe oxidizers.

For specialized applications, contact our engineering team with the operating conditions and materials involved so we can help confirm the appropriate LOX-8 product.
