PTFE WATER SHAFT SEAL & PTFE OIL SHAFT SEAL

PTFE WATER SEAL & PTFE OIL SEAL

Dual sealing solutions for industrial durability and reliability

In modern industrial systems, where hydraulic, pneumatic, and lubrication components demand absolute sealing, leak protection, and chemical resistance, choosing the right shaft seal is critical to the efficiency and longevity of machinery.

Recognizing this need, Anh Tri Tue Company has developed two advanced sealing solutions:

  • PTFE Water Seal – designed to prevent water ingress and protect bearing housings.
  • PTFE Oil Seal – designed to prevent lubricant leakage and withstand high pressure and temperature.

Both products utilize the ATT–FluoroEtch® surface treatment technology, which enables perfect adhesion between PTFE and technical rubber, resulting in superior durability, leak resistance, and chemical stability.

  1. Advanced Technology – Strong Bond Between PTFE and Rubber

PTFE (Polytetrafluoroethylene) is known for its chemical inertness, low friction coefficient, and heat resistance up to 250°C, yet it is difficult to bond with other materials. Through the ATT–FluoroEtch® process, the PTFE surface is activated, allowing strong chemical bonding with technical rubber during vulcanization. This creates a mechanically and chemically stable interlayer, maintaining tight sealing performance in oil, water, and high-temperature environments.

  1. Outstanding Performance in Harsh Conditions

Both PTFE Water Seals and PTFE Oil Seals from Anh Tri Tue deliver:

  •  Perfect sealing performance – prevent leakage of water, oil, and solvents under pressure.
  •  Excellent resistance to heat and chemicals – suitable for acids, alkalis, and industrial lubricants.
  •  Extended service life – reduce wear, downtime, and maintenance costs.
  •  Customizable design – adaptable to different shaft sizes, pressures, and environments.
  1. Typical Applications
  • Steel industry: Rolling shafts, rotary shafts.
  • Oil & gas: Hydraulic and pneumatic sealing systems.
  • Automotive: Crankshaft and camshaft seals.
  • Medical & precision equipment: High cleanliness and chemical resistance required.
  1. Proven Performance in the Steel Rolling Industry

In steel rolling operations, seals must endure:

  • Temperatures from 80–120°C,
  • High vibration and heavy loads,
  • Constant exposure to cooling water, lubricants, and metal dust.

Even small leaks can cause oxidation, bearing failure, or production stoppages, costing hundreds of millions of VND per hour.

Anh Tri Tue’s PTFE seals have been successfully applied at Steel Plant for:

  • PTFE Oil Seals on rolling shaft bearings – preventing lubricant leakage and ensuring stable operation.
  • PTFE Water Seals on cooling shafts – preventing water intrusion into oil chambers and bearing areas.

Actual results:

  • No leakage at high shaft speeds.
  • No deformation under heat and load.
  • Seal lifespan 2–3 times longer than conventional rubber seals.
  • Reduced maintenance and operating costs.
