OC® Three PTFE Paste Joint and Thread Sealer

Joint and Thread Sealer

Solutions for critical and demanding applications where no flammability, compatibility with oxygen and resistance to aggressive chemicals are essential.

OC® Three PTFE Paste Joint and Thread Sealer is an oxygen-safe, aqueous-based PTFE formulation. It is a homogeneous white paste that penetrates thread convolutions more effectively, and more safely, than PTFE tape. Tested, approved and certified by NASA (ASTM G72) and The German Federal Institute for Materials Testing (BAM) for gaseous and liquid oxygen service. OC® Three is approved and used by the major industrial gas providers, and it is NSF registered. Use in extreme temperatures (from cryogenic to +500º F) and as a vacuum grease for mid vacuum specifications to 10-3 Torr or in pressures for specific applications up to 10,000 psi. OC® Three is especially capable for sealing oxygen and acetylene cylinder valves. It is compatible with diesel fuel, liquid propane gas, and pure oxygen. OC® Three is safe for use with food processing applications. It is easy to apply from its 4 oz. (113.4 gram) squeeze tube with extended nipple and resealing cap. OC® Three is a superior PTFE thread sealant paste that contains these optimal properties:
•Water Soluble, Anti-Galling, Anti-Corrosive, Anti-Seize, Chemically Inert, Non-Toxic, Non-Flammable, Non-Migrating, Odorless
•Tested and certified for gaseous and liquid oxygen service by the Federal Institute For Materials Testing (BAM)
• NASA (ASTM G72) approved for use with oxygen
• NSF registered for use in food processing facilities, classification S2
• Approved for use and listed in the resource manuals of the major industrial gas providers
• PFOA, PFOS, silicone, hydrocarbon, and solvent free
• Easier to apply than tape (adheres to threads) and does not cold flow
• Use over a wide temperature range: from cryogenic temperatures to over 286°C (over 500°F)
• Resistant to aggressive chemicals

OC Three is compatible with many systems in liquid, gas, and vacuum service. The applications include:

Bottled gas valves
Natural gas
Cryogenic
Oxygen systems
High temperature sealing paste
Plumbing
Sensors for machines
Medical
Aerospace
Chlorine (gaseous and liquid)
