Types of Molded Gaskets& Seals
The molded gaskets& seals produced by our company mainly include the following types:
Nitirle Gasket
Nitrile gasket is a type of sealing device used to prevent gas or fluid leakage between machine parts or pipe joints. It is made of nitrile rubber, a synthetic rubber material that offers resistance to oil, solvents and weathering.
Molded Rubber Seals
Molded rubber sealing parts are a type of sealing product that vulcanizes rubber raw materials (natural rubber or synthetic rubber) through molds by applying pressure and heating.
Bonded Seal Kit
Bonded seal kit is a combined sealing solution integrating metal and elastic sealing materials, including multiple uniform or matching adhesive seals of various specifications, and is widely used for sealing of threaded or flange connections in fields such as hydraulics, pneumatics, and mechanical engineering.

Nitirle Gasket
Nitrile gasket is a type of sealing device used to prevent gas or fluid leakage between machine parts or pipe joints. It is made of nitrile rubber, a synthetic rubber material that offers resistance to oil, solvents and weathering.
Molded Rubber Seals

Bonded Seal Kit
Bonded seal kit is a combined sealing solution integrating metal and elastic sealing materials, including multiple uniform or matching adhesive seals of various specifications, and is widely used for sealing of threaded or flange connections in fields such as hydraulics, pneumatics, and mechanical engineering.
Enhanced design options
Using custom molds, you can generate three-dimensional gaskets, integrate additional parts into your mold’s design, create parts with varying cross-sections, incorporate engraving, and more.
Dimensional accuracy
Molded gaskets offer tighter tolerances than cut gaskets, particularly where thickness is concerned. They create a secure bond between surfaces while enabling joint flexibility.
Improved leakage protection
Molded gaskets don’t have splices, creating fewer opportunities for leakage.
Minimal waste
Molding generates little material waste, which equates to the added benefit of per-part cost reductions.
Automotive Industry
Molded gaskets are used in engines, transmissions, and other critical automotive components to prevent leaks and ensure proper sealing.
HVAC Systems
They are utilized in heating, ventilation, and air conditioning systems to maintain airtight seals and improve energy efficiency.
Plumbing and Pipelines
Molded gaskets play a crucial role in water and gas distribution systems, ensuring leak-free connections and preventing fluid escape.
Electronics
They are used in electronic devices to provide protection against dust, moisture, and electromagnetic interference.
Aerospace
In aircraft and spacecraft, molded gaskets are vital for maintaining cabin pressure, preventing fuel leaks, and ensuring the integrity of sensitive equipment.
Medical Devices
Molded gaskets are used in medical devices and equipment to create sterile environments and seal sensitive components.
Industrial Machinery
They are integral to the functioning of heavy machinery, preventing oil, coolant, and hydraulic fluid leaks.
EPDM (Ethylene Propylene Diene Monomer)
EPDM is renowned for its excellent resistance to weathering, ozone, and UV exposure, making it ideal for outdoor applications. It performs well in a temperature range of -40°F to 250°F and exhibits good resistance to water and steam.
Viton (Fluorocarbon Rubber)
Viton offers exceptional chemical resistance, particularly to fuels, oils, and aggressive solvents. It maintains its properties in high-temperature environments, with a typical operating range of -15°F to 400°F.
Nitrile (Acrylonitrile Butadiene Rubber)
Nitrile is valued for its excellent resistance to oils, fuels, and other petroleum-based products. It operates effectively within a temperature range of -40°F to 275°F.
Silicone
Silicone rubber is known for its outstanding thermal stability, remaining flexible at temperatures ranging from -75°F to 500°F. It is also resistant to ozone and UV radiation.
Neoprene (Chloroprene Rubber)
Neoprene provides a balanced combination of properties, including resistance to weathering, ozone, and moderate chemicals. It operates effectively between -40°F and 225°F.
Storage Precautions for Molded Gaskets& Seals
Temperature Control
Store gaskets in a cool, dry area. Ideally, the temperature should be kept between 59°F and 77°F (15°C to 25°C). Excess heat can accelerate rubber aging.
01
Humidity Control
Maintain a relative humidity of below 75%. High humidity promotes mold growth and material softening.
02
Avoid Light Exposure
Keep gaskets away from direct sunlight or artificial UV sources. UV light can cause rubber to become brittle and cracked over time.
03
Air Quality
Ozone in the air can damage rubber materials. Avoid storing gaskets near equipment that emits ozone, such as electric motors.
04
Stacking and Compression
Avoid placing heavy objects on stored gaskets. Over-compression can distort their shape, rendering them ineffective upon installation.
