Rail Transit Seals

Door and Window Seals

Waterproofing、Dustproofing、Noise reduction、Vibration damping

Application: Used for sealing the edges of train doors and windows to prevent rain, dust, and noise from entering the carriage, while cushioning the impact during door opening/closing.

Rubber Types: EPDM (excellent weather and aging resistance), Silicone (superior high/low-temperature resistance).

Functions: Waterproofing, dustproofing, noise reduction, vibration damping.

Intercarriage Connection Seals

Pneumatic sealing.Vibration resistance、Temperature variation resistance

Application: Sealing devices for connecting carriages (e.g., gangway seals), adapting to vibrations, displacements, and temperature changes during operation to ensure airtightness and passenger safety.

Rubber Types: Neoprene (good weather and ozone resistance), EPDM (high flexibility for dynamic deformation).

Functions: Pneumatic sealing, vibration resistance, temperature variation resistance.

Bogey and Suspension System Seals

Oil leakage prevention、Dust and water resistance、Wear resistance

Application: Sealing bearings and suspension components in bogies to prevent lubricant leakage and block external contaminants (water, dust, gravel) from entering, ensuring lubrication and service life of mechanical parts.

Rubber Types: NBR (excellent oil resistance), HNBR (superior high/low-temperature and oil resistance).

Functions: Oil leakage prevention, dust/water resistance, wear resistance.

Electrical Equipment Seals

Insulation protection、Moisture and dust prevention、Electrical corrosion resistance

Application: Sealing cable joints, distribution boxes, and high-voltage equipment to prevent moisture and dust from entering, ensuring the insulation and safety of electrical systems, especially in wet or dusty environments.

Rubber Types: Silicone (good insulation and corona resistance), FKM (high-temperature and chemical corrosion resistance).

Functions: Insulation protection, moisture/dust prevention, electrical corrosion resistance.

Rail and Bridge Joint Seals

Shock absorption、Joint filling、Weather and water resistance

Application: Filling joints in rail connections and bridge bearings to absorb vibrations and displacements when trains pass, reduce noise, and prevent rainwater from penetrating the track structure.

Rubber Types: EPDM (high elasticity and weather resistance), Neoprene (tear resistance, aging resistance).

Functions: Shock absorption, joint filling, weather/water resistance.

Air Conditioning and Ventilation System Seals

Airtight sealing、Temperature resistance、Dust prevention。

Application: Sealing air conditioning units and ventilation ducts to ensure efficient air flow, prevent leakage of hot/cold air, and block dust and foreign objects from entering the system.

Rubber Types: EPDM (moderate weather and temperature resistance), Silicone (suitable for high/low-temperature sealing).

Functions: Airtight sealing, temperature resistance, dust prevention.
