Copaltite Sealant for Hydraulic Systems

Copaltite seals hydraulic system threaded connections, flanged joints, and high-pressure fittings against hydraulic fluid under full system operating pressure. It resists all hydraulic fluids, does not flow or creep under sustained hydraulic pressure, and withstands the vibration inherent in hydraulic systems — making it the standard hydraulic system pipe sealant for industrial, marine, aviation, and heavy equipment applications across the UAE and GCC.

Why Hydraulic Systems Demand a High-Performance Thread Sealant

system — industrial hydraulic circuits routinely operate at 3,000 to 5,000 PSI, with some systems exceeding 10,000 PSI. Every threaded fitting, port connection, and flanged joint in the system must maintain an absolute seal against hydraulic fluid at this pressure, continuously, through the vibration and pressure cycling inherent in hydraulic operation.

Standard PTFE tape is widely misused in hydraulic systems and frequently causes failures — it can shred into particles that contaminate hydraulic fluid, it flows under sustained high pressure, and it does not provide the sealing torque that high-pressure hydraulic connections require. A higher-performance solution is needed for hydraulic system thread sealing.

Why Copaltite Is Used in Hydraulic Systems

  • Resists all hydraulic fluids — mineral oil-based, synthetic, and water-based hydraulic fluids
  • Does not flow or creep under sustained hydraulic pressure
  • Withstands severe vibration without cracking or delaminating
  • Effective from -315°F to 1500°F — covers hydraulic systems from sub-zero to high-temperature service
  • Does not contaminate hydraulic fluid — no particles that can damage valves, seals, or actuators
  • Anti-seize — hydraulic fittings can be disassembled cleanly for maintenance and component replacement
  • Copaltite Liquid Form is the standard product for hydraulic thread and machined connections

Copaltite Liquid Form vs. Cement Form for Hydraulic Systems

Copaltite Liquid Form is the product of choice for precision machined turbine flanges and threaded connections where surfaces are in good condition and close tolerances are maintained. Its smooth paste spreads evenly across machined surfaces and provides a clean, tight seal.

Copaltite Cement Form is the preferred option for main body flanges with surface imperfections, warped joint faces, scored seating surfaces, and aged turbine casings where gap-filling capability is needed to compensate for surface condition.

Both products share the same temperature range, MIL-S-15204D qualification, chemical resistance, and anti-seize properties.

Frequently Asked Questions

What is the best thread sealant for high-pressure hydraulic fittings?

Copaltite Liquid Form is the standard pipe thread sealant for high-pressure hydraulic connections. It does not flow under sustained hydraulic pressure, resists all hydraulic fluids, and does not shed particles that could contaminate the hydraulic circuit.

Can Copaltite be used on all types of hydraulic fluid?

Yes. Copaltite resists mineral oil-based, synthetic, and water-based hydraulic fluids — covering all common hydraulic system working fluids in industrial, marine, aviation, and mobile equipment applications.

Does Copaltite contaminate hydraulic fluid?

No. Unlike PTFE tape, Copaltite does not shed particles into the hydraulic circuit. Once cured, it forms a stable, non-migrating seal that does not contaminate the hydraulic fluid.
