Products Dental chairs rubber seals Description
Dental chairs' rubber seals
The rubber seals used in dental chairs are typically made of heat-, pressure- and chemical-resistant rubber. Common rubber materials include the following
Nitrile Rubber: Nitrile rubber has good oil resistance, wear resistance, and chemical resistance, and can withstand certain temperatures and pressures. It is typically used where the seal needs to come into contact with lubricants or chemicals.
Fluoroelastomer: Fluoroelastomer has excellent high-temperature resistance and chemical corrosion resistance, and can maintain elasticity and reliable sealing at higher temperatures. It is commonly used in seals requiring high temperature and chemical resistance.
Ethylene Propylene Rubber (EPDM): Ethylene propylene rubber has good heat resistance and ozone resistance, as well as excellent weather resistance and electrical insulation properties. It is often used in outdoor environments or seals that require weathering and aging resistance.
Silicone Rubber: Silicone rubber has excellent high-temperature resistance and good elasticity, as well as excellent electrical insulation and air tightness. It is typically used in applications where sealing performance needs to be maintained in high-temperature environments.
There are a wide variety of rubber seals used in dental chairs, and the design and construction of each chair may vary. Here is a closer look at some of the rubber seals that may be used on some common dental chairs:
- Seat Seal: The seat seal is the rubber seal located at the junction of the dental chair seat and base. Its function is to prevent liquid or dirt from entering the gap between the chair seat and base, ensuring sealing performance and preventing contamination.
- Cylinder Seals: Dental chair lift systems often use cylinders to adjust the height of the chair. Cylinder seals are located between the piston and cylinder barrel of the cylinder to prevent gas or liquid leakage. It ensures the normal operation and stability of the cylinder.
- Water pipe connection seals: Rubber seals may be used at the water pipe connections in the dental chair to ensure a tight seal at the connection and prevent water leakage or leakage. These connections include water inlets, water spray guns, and suction pipes.
- Light pole seal: The surgical light on the dental chair is usually supported by an adjustable light pole. A rubber sealing ring may be used at the connection between the light pole and the chair to ensure the stability of the light fixture and prevent the light pole from shaking.
- Pipe seals: Rubber seals may be used at various pipe connections in the dental chair, such as suction, drain, and airlines. These seals ensure the proper operation of liquid, gas, or vacuum systems and prevent leaks and cross-contamination.

dental chair seat seal
The dental chair seat seal is a rubber seal located at the junction of the chair seat and base. Its function is to prevent liquids, dirt and impurities from entering the gap between the seat and base, ensuring sealing performance and preventing contamination.
Seat sealing rings are usually made of wear-resistant, pressure-resistant and chemical-resistant rubber materials. The rubber material needs to be elastic and durable enough to withstand the pressure and friction between the seat and base.
The shape and size of the chair seat seal ring will vary depending on the design and construction of different dental chairs. It is usually a ring-shaped rubber gasket located at the bottom of the chair seat to form a seal with the contact surface of the base.
Products Dental chair cylinder seal Description
A dental chair's cylinder seal is a rubber seal located between the cylinder's piston and cylinder barrel. Its main function is to ensure the sealing performance of the cylinder, prevent gas or liquid leakage, and maintain the normal operation of the cylinder.
Cylinder seals are usually made of wear-resistant, pressure-resistant, and chemical-resistant rubber materials. This rubber material needs to have good elasticity and durability to withstand the pressure and friction inside the cylinder.
The shape and size of the cylinder seal will vary depending on the design and construction of different dental chairs. It is usually an annular or band-shaped rubber sealing element installed on the piston of the cylinder to form a seal with the cylinder barrel.
Products Dental chair water pipe connection seals Description
Dental chair water pipe connection seals
Dental chair water pipe connection seals are used to ensure the sealing performance of water pipe connections to prevent water leakage or leakage. Here are several common dental chair water connection seals:
- O-ring: O-ring is an annular rubber seal commonly used at water pipe connections. Its circular cross-section provides a good sealing effect. O-rings are suitable for connecting pipes of different sizes and have good pressure resistance.
- Thread sealants: Thread sealants may be used on some water pipe connections, especially threaded connections. This seal is usually made of a soft rubber material that fills and seals the gaps between the threads to prevent water leakage or leakage.
- Water pipe joint sealing ring: The water pipe joint sealing ring is usually used to connect water source inlet, water spray gun, water suction pipe, and other components. They are usually ring-shaped seals made of rubber or silicone that ensure the sealing properties of the joint and prevent water leakage or leakage.
- The material of these water pipe connection seals is usually selected from rubber materials that are durable, wear-resistant, and chemical-resistant. They need to have good elasticity and durability to withstand water pressure and frequent connection and removal operations.
- When maintaining and replacing waterline connection seals, the appropriate seal should be selected based on the design and construction of the specific dental chair.
Products dental chair light pole sealing ring Description
Dental chair light pole sealing ring
The dental chair light pole sealing ring is a rubber sealing fitting located between the light pole and the light base. Its function is to ensure the sealing performance between the lamp pole and the lamp holder, prevent dust, liquid, or other impurities inside the lamp holder from entering, and prevent the wire or power supply from contacting the external environment.
Light pole sealing rings are usually made of wear-resistant, pressure-resistant, and chemical-resistant rubber materials. This rubber material needs to have good elasticity and durability to withstand the pressure and friction between the light pole and the light base.
The shape and size of the light pole sealing ring will vary depending on the design and construction of different dental chairs. It is usually a ring-shaped rubber gasket located at the bottom of the lamp pole to form a seal with the contact surface of the lamp holder.
