Nitrile gas-tight sealing ring

Outer diameter expansion: The outer diameter expansion type inflatable sealing ring. When the cavity is inflated and pressurized, the outer ring expands and expands outward, causing the outer diameter to increase and fitting tightly against the inner wall of the cavity groove, thereby achieving a sealing and isolation effect. In the non-inflated state, the rubber ring shrinks in size and has a smaller outer diameter, making installation and disassembly simple and convenient; after introducing air pressure, the entire ring expands outward, filling the gaps in the equipment and fully adhering to the sealing surface. It can automatically compensate for the deviation of equipment gaps, ensuring uniform and stable sealing performance, and is suitable for use in warehouse doors, flanges, box body slots, and pipe outer walls. After deflation, it automatically retracts, reducing friction loss, and can be repeatedly used. It has good aging resistance and pressure resistance. Our advantages: We can adopt our self-developed formula for segmented vulcanization process, and the entire process does not require customizing a complete set of molding molds, significantly reducing production costs. There is no need to wait for the mold processing cycle; once an order is received, production can begin immediately, and the delivery cycle is faster. We can produce products of any large diameter, unconventional non-standard specifications at will, and the specifications are not limited by molds. Small batch, multi-model orders can be flexibly produced, and the product versatility is stronger.

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.

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.
