Customized service

Our inflatable sealing rings can be customized comprehensively and precisely, with options available for raw materials, cross-sectional styles, dimensions and wall thicknesses, inflation nozzles, sealing expansion directions, and exterior colors, all tailored to meet customer needs in a one-stop solution.

Material selection

Select materials based on the actual operating conditions of the equipment. For food and pharmaceutical clean environments, silicone materials are used, which are non-toxic, odorless, resistant to high and low temperatures, and can withstand up to 300 degrees. For outdoor aging and dust-proof working conditions, EPDM rubber is selected, which is resistant to ozone and weathering; for contact with oil-contaminated media, nitrile rubber is used, which is resistant to oil and wear; for harsh conditions of strong acid and alkali, high-temperature corrosion, fluorine rubber materials are selected, which have stronger corrosion resistance. Various raw materials are reasonably distinguished to adapt to different operating temperatures and media.

Section style

A variety of common cross-sections are available, including circular, square, D-shaped, C-shaped, and trapezoidal. According to the width of the installation slot and the installation structure, different shaped cross-sections can be customized to fit the installation slot structure, ensuring stable placement without falling off. It is suitable for both fixed and embedded installation methods.

Size and wall thickness

All can be customized freely. There are no restrictions on the overall perimeter length and thickness specifications. The thickness of the rubber layer can be adjusted. Based on the actual usage scenario and pressure level, the wall thickness suitable for the customer's actual needs will be designed. Reasonably control the wall thickness parameters to balance the sealing force and service life.

Inflator nozzle model

Support customization, including built-in concealed air nozzles, external straight nozzles, and curved nozzles. The length, installation position, and quantity can all be adjusted. A single air nozzle is typically used, while large-sized circular sealing frames can be equipped with two air nozzles, ensuring more uniform inflation, faster air intake speed, and facilitating pipeline connection and installation.

Customize your product

Expansion sealing direction

It is divided into three types: inward expansion, outward radial expansion, and upward-downward axial expansion. The expansion direction is customized according to the position of the equipment's sealing gap, precisely aligning with the sealing contact surface. There will be no force deviation, and the sealing becomes more secure.

Customize your product

Appearance color

All can be uniformly produced. Colors such as red, transparent, white, and blue can all be mixed. Not only is it elegant and decent, but it can also distinguish the rubber material by color, facilitating later management and distinction. The overall product is comprehensively customized in a refined manner, and every high-quality sealing product is meticulously crafted.

The Nen Qi Tia category

The pneumatic flange, also known as the pneumatic flange by-nut / inflated by-nut, is a large-diameter, low-pressure, quick-installation and quick-disassembly pipe sealing connection component. It achieves sealing and connection by using an inflated rubber air tire to grip the steel pipe. Its main features include large misalignment compensation and tool-free disassembly and assembly.

Air clutch

The pneumatic clutch (also known as air bag/air expansion clutch) is a dry friction clutch that uses compressed air as power and relies on the expansion of rubber air tires to push the friction blocks to tightly grip the driven drum to transmit large torque. It also has the function of an elastic coupling. Industrial rubber clutch airbags, brake airbags, and brake tires are highly resilient, resistant to impact, and fatigue-resistant, and are used in industrial clutches, brakes, and pneumatic braking systems of transmission equipment.

Shield machine suction cup sealing strip

The suction cup sealing strip of the shield machine is a ring-shaped or I-shaped foamed rubber strip installed on the vacuum suction cup surface of the assembly machine. Its function is to closely adhere to the inner arc of the pipe segment, form a sealed cavity, evacuate air to create negative pressure, and firmly hold concrete pipe segments weighing several tons to tens of tons, completing the grasping, transportation and assembly processes.

Dust cover

Dust Cover: The dust cover is also known as an extensible protective sleeve or a corrugated dust cover. It is a rubber protective plastic accessory, mainly made of high-quality rubber raw materials through vulcanization. It comes in various styles such as corrugated folding type, integrated cylindrical type, and closed type. The overall flexibility of the product is excellent, with good expansion and rebound effects, and it is resistant to pulling without cracking. Its main functions are dust prevention, waterproofing, oil and dirt prevention, sand prevention, rust prevention and corrosion prevention. It can isolate external dust and debris, rainwater impurities, avoiding long-term exposure of mechanical components to wear, rust, aging and jamming. The dust cover has excellent resistance to high and low temperatures, aging and friction. It has a large expansion stroke, flexible compression and folding, easy installation, and excellent sealing performance. It can freely expand and swing with the mechanical movement without affecting the normal operation of the equipment. It is widely used in engineering machinery, automotive parts, hydraulic piston rods, connecting rods, transmission shafts, shock absorbers, mechanical equipment connection parts, precision instruments, etc. It effectively reduces part wear, lowers equipment maintenance frequency, and extends the overall service life of mechanical components.

Fluorine rubber sealing ring

Fluorine rubber sealing ring: The fluorine rubber sealing ring is simply called the fluorine rubber sealing ring. It is currently the most advanced sealing product with extremely strong comprehensive performance in industrial sealing. It is made by high-temperature vulcanization of fluorine rubber material. The product has excellent high-temperature resistance, low-temperature resistance, acid and alkali resistance, oil resistance, solvent resistance, corrosion resistance, and its antioxidant and anti-aging ability far exceeds that of ordinary rubber materials. The fluorine rubber material can withstand a high temperature of up to 230℃, and can withstand a short-term maximum temperature of 300℃. It has good low-temperature toughness and is not prone to hardening or cracking. At the same time, it can resist the erosion of engine oil, hydraulic oil, chemical corrosive liquids, ozone and ultraviolet rays, and is not prone to deformation, swelling, aging or deterioration during long-term use. The sealing density is high, the rebound performance is excellent, the compression permanent deformation is small, it is wear-resistant and pressure-resistant, the sealing effect is stable, and the service life is more durable. Advantages: We have multiple molds that can meet most of the specifications and models in the market. Generally, there is no need for additional mold opening costs.
