Our Advantages

As a professional manufacturer specializing in inflatable sealing rings, our factory boasts a complete integrated production and processing line. We independently handle everything from raw material refining, mold processing, high-temperature vulcanization, precision grinding, to air tightness testing. This gives us numerous production advantages over ordinary distributors.

Advantages in raw material production and mold processing

The manufacturer independently blends and compounds rubber, using only high-quality virgin rubber as raw material and avoiding recycled waste materials. The rubber's hardness, flexibility, temperature resistance, and corrosion resistance can be adjusted according to the usage environment. The rubber is dense and compact, with better elastic rebound, and is less prone to aging, cracking, air leakage, and deformation over long-term use. The quality of raw materials is controllable. Our factory has its own mold research and development workshop, with a complete inventory of regular style molds. Various irregular and non-standard complex shapes can be quickly customized without outsourcing processing, shortening the production cycle. Various sections, irregular corners, and special sizes can be processed in one piece.

Advantages in craftsmanship and production

Using our proprietary formula and segmented vulcanization process, there's no need to customize a complete set of molding tools throughout the entire process, significantly reducing production costs. There's no need to wait for the mold processing cycle; production can begin immediately upon receiving an order, resulting in a faster delivery cycle. In addition, the overall seamless vulcanization process ensures that the entire sealing ring is molded in one piece, with tight joints and no splicing gaps, eliminating common issues such as air and water leakage at the joints. The craftsmanship is exquisite, with thick rubber quality, smooth edges and corners, and higher installation fit. The overall workmanship far exceeds that of products made through splicing processes.

Detect quality advantages

Every finished product undergoes rigorous testing for airtightness, pressure resistance, and long-term pressure maintenance, eliminating defective and flawed items. Strict control is maintained over wall thickness uniformity, inflation strength, and expansion performance, resulting in a higher pass rate and enhanced sealing stability upon delivery.

Customization and supply advantages

The manufacturer's production specifications are not restricted, and wall thickness, air nozzle, expansion direction, color, and material can all be customized according to individual needs. With ample inventory, regular products are available for immediate shipment, and non-standard orders are shipped quickly. We provide stable and large-scale supply throughout the year. By eliminating middlemen's price differences, our factory-direct sales offer affordable prices and higher cost-effectiveness. We also provide comprehensive after-sales technical support to fully guarantee customer procurement and use.

Frequently Asked Questions

The pressure of the inflatable sealing ring

The normal inflation pressure for the standard type of sealing ring is 1-2 kilograms (0.1-0.2 MPa). Gradually increase the pressure for optimal sealing condition and use it to expand and seal the sealing ring. If you want to withstand greater pressure, through reasonable design and manufacturing, it can also withstand high pressure.

The characteristics of the inflatable sealing ring

1. The sealing gap is large and it has strong adaptability. Ordinary O-rings can only seal very small gaps. The inflatable ring can seal gaps of 0.5 to 5mm or even larger, with low requirements for processing accuracy. 2. It can be actively opened and closed, and is flexible to use. Inflation: Expansion and compression to achieve sealing/holding/blocking Deflation: Rapid contraction and reset, without friction or jamming It is particularly suitable for scenarios with frequent opening and closing and where the workpiece needs to pass through. 3. The sealing surface has good adaptability. It can self-adapt and fit for non-round, elliptical, slight deformation, rough surfaces, and flange misalignment. Ordinary hard seals are difficult to achieve this. 4. The pressure is controllable and the sealing force can be adjusted. The expansion force can be controlled by adjusting the air pressure. It can be used for both light and heavy loads, and it is not likely to damage soft workpieces (plastics, glass, thin-walled parts). 5. There is no friction or wear, and the lifespan is long. It only comes into contact during inflation, and it does not have friction in non-working states. It is much more durable than conventional sealing rings. 6. Installation is simple and the versatility is high. No complex and precise grooves are needed. Simple grooves or steps can be used for installation. It can also be made into square, rectangular, or special-shaped rings.

How to choose an inflatable sealing ring

1. First, let's look at the installation methods: 1. Outer diameter expansion pneumatic sealing ring: After inflation, it expands outward and presses against the outer cylindrical cavity, with the sealing surface on the outside. It is suitable for large gaps and large dimensional tolerances. 2. Inner diameter expansion pneumatic sealing ring: After inflation, it tightens inwardly. It has strong clamping force. 3. End face (axial) expansion pneumatic sealing ring: After inflation, it bulges and expands along the height direction, pressing against the opposite plane to form a seal. 2. Select the material based on the usage environment: 1. Silicone: Use imported silicone material. It is resistant to high and low temperatures, -60℃ to 300℃. 2. Ethylene Propylene Diene Monomer (EPDM): Resistant to acid and alkali corrosion, aging-resistant, ozone-resistant, and heat-resistant. Suitable temperature range: -60 to 130℃, but not resistant to oil-based media. 3. Nitrile Butadiene Rubber (NBR): Good oil resistance, high wear resistance, suitable for environments with oil contamination. Poor in low-temperature resistance and ozone resistance. 4. Fluorine rubber: Resistant to high temperatures, oil, acids and alkalis, corrosion-resistant, all-in-one material. 3. Select the size of the gap: 1. Small gap: Ordinary circular cross-section 2. Large gap, large tolerance: Select rectangular/irregular cross-section, or add a high expansion amount of the outer expansion sealing ring 3. Irregular surface, uneven surface: Select custom-shaped pneumatic sealing ring 4. Select the installation space: 1. Sufficient slot width and depth: Select standard O-type pneumatic sealing ring 2. Narrow space: Select flat, thin pneumatic sealing ring 3. Requires quick disassembly and assembly: Select open type, snap type
