National Engineering Products, Inc. sealant COPALTITE™ serves a broad range of manufacturing and repair needs

  • Copaltite liquid tube and cement can

COPALTITE

COPALTITE is used across a broad spectrum of heavy machinery and manufacturing – from shipbuilding and turbine maintenance to commercial and residential maintenance and more – to seal threaded and flanged joints.

The industry’s global, gold standard for 90 years, COPALTITE creates high-performance seals you can count on.

  • Room full of refrigeration compressors and associated controls for ice production.
  • Sealing compound for marine turbines operating at
    950° F and 1200 psi
  • Seals flanges without gaskets up to 6,500 psi
  • Effective for steam joints at 1200° F and 2000 psi
  • Holds threaded joints up to 10,000 psi
  • Resists corrosive chemicals, gasoline, ammonia, brine, propane, refrigerants, hydrocarbons, hydraulic fluids, mild alkalis and other common reagents, even at elevated temperatures.

Comes in two, ready-to-use forms:

  • Liquid form for use on pipe threads and smooth surfaces
  • Cement (paste) form for use on rough or scored surfaces
  • Both forms are available in 5-oz. flexible tubes and quart-size containers
  • Copaltite liquid tube and cement can

Industrial Applications

So resistant to high pressures and temperatures, COPALTITE’s successful use on turbines has demonstrated its viability and mission-readiness across many other manufacturing and machine repair scenarios. It is now widely used on pumps; valve seats; flanges; boiler manhole and handhold covers; condensers, and hydraulic systems. Industries such as oil; steel; pulp and paper; heavy equipment; aviation; automotive; chemical, and marine have used and continue using COPALTITE to address many daily maintenance problems.

  • The benefits of COPALTITE have been proven through use at shipyards and sealing joints holding 7,500 pounds of air pressure. Its immunity to vibration, thermal shock, and chemicals is unmatched. And, although the seal is permanent, it may be broken. COPALTITE adheres to metals, ceramics, rubber, and most plastics. Numerous industries – from construction, power, oil & gas, mining, and heavy equipment to marine, automotive, steel, pulp & paper, and locomotive – typically use COPALTITE on equipment such as:
    • Steam Turbines
    • Heat Exchanges
    • Hydraulic systems
    • Pressure Vessels
    • Pressure Gas Lines
    • Refrigeration lines
    • Condensers
    • Boilers
    • Compressors
  • The efficient, effective operation of turbines and auxiliaries that are so sensitive to high pressures and extreme temperatures depends largely on the security of all joints. Petrochemical companies successfully use COPALTITE on steam joints at 2,000 psi and 1200° F And it has proven to be the perfect sealing agent for joints and turbine main body flanges.
  • Latch on the pipeline. Oil refinery. Equipment for primary oil refining.
  • Power stations nationwide report that COPALTITE has successfully held even badly warped turbine joints after other methods failed, delivering safe, continuous operation and huge savings. One case reported to a COPALTITE reseller stated that $1.80 worth of COPALTITE sealed a turbine unit after thousands had been spent unsuccessfully to do so.
  • COPALTITE meets all U.S. Navy test requirements for use on marine turbines at 1200 psi and 950°F (MIL-S-15204D), and the marine industry has used COPALTITE for It competently handles the high pressures and temperatures found on steam-driven power plants at sea, and numerous shipbuilders and steamship operators demand that only COPALTITE be used to repair them and maintain general operations.
