Rubber O-ring Manufacturers

Rubber O-ring seals are suitable for installation on various mechanical equipment, and play a sealing role in static or moving states under specified temperature, pressure, and different liquid and gas media. Various types of sealing elements are widely used in sanitary ware, ships, automobiles, hardware, electronics, toys, electrical appliances, aerospace equipment, machinery, and various instruments and meters. Rubber O-rings are mainly used for static sealing and reciprocating motion sealing. When used for rotary motion sealing, it is limited to low-speed rotary sealing devices. The rubber O-ring is generally installed in a groove with a rectangular cross-section on the outer circle or the inner circle to act as a seal. Rubber O-ring seals still play a good role in sealing and shock absorption in environments such as oil resistance, acid and alkali, abrasion, and chemical erosion. Therefore, the rubber O-ring is the most widely used seal in hydraulic and pneumatic transmission systems. Advantage Compared with other types of sealing rings, the rubber O-ring has the following advantages: 1. Suitable for various sealing forms: static sealing, dynamic sealing, Suitable for a variety of materials, dimensions and grooves have been standardized, strong interchangeability 2. Suitable for a variety of motion modes: rotary motion, axial reciprocating motion or combined motion (such as rotary reciprocating combined motion) 3. Suitable for a variety of different sealing media: oil, water, gas, chemical media or other mixed media Through the selection of suitable rubber materials and proper formula design, the effective sealing effect on oil, water, air, gas and various chemical media can be realized. The temperature range is wide (- 60 ℃ ~ 220 ℃), and the pressure can reach 1500Kg/cm2 in fixed use (used together with the reinforcing ring). 4. Simple design, compact structure, easy assembly and disassembly The section structure of the rubber O-ring is extremely simple, and has a self-sealing function, and the sealing performance is reliable. Since the structure of the rubber O-ring itself and the installation part are extremely simple and standardized, installation and replacement are very easy. 5. Many kinds of materials Can be selected according to different fluids: nitrile rubber (NBR), fluorine rubber (FKM), silicone rubber (SIL), ethylene propylene diene monomer (EPDM), neoprene rubber (CR), natural rubber (NR) hydrogenated Nitrile rubber (HNBR), butyl rubber (IIR), silicone fluororubber (FLS), etc.

What Are The Advantages of Using Rubber O-Ring Seals?

Rubber O-ring seals offer several advantages over other sealing solutions. Some of the advantages of using rubber O-ring seals include:

(1)High sealing efficiency: Rubber O-ring seals provide an excellent sealing performance, even in high-pressure and high-temperature applications.

(2)Versatility: O-ring seals can be used in a wide range of applications, from hydraulic and pneumatic systems to automotive and aerospace industries.

(3)Cost-effective: Rubber O-ring seals are generally less expensive than other types of seals, making them a cost-effective solution for many applications.

(4)Easy to install: O-ring seals are easy to install and do not require any special tools or equipment.

(5)Resistant to a wide range of chemicals: Rubber O-ring seals are resistant to a wide range of chemicals, making them suitable for use in harsh environments.

(6)Low maintenance: O-ring seals require minimal maintenance and are designed to last for extended periods of time.

(7)Wide temperature range: Rubber O-ring seals can withstand a wide range of temperatures, from very low to very high.

(8)Good compression set resistance: Rubber O-ring seals can maintain their sealing performance over extended periods of use, without experiencing any significant compression set.

(9)Excellent durability: Rubber O-ring seals are designed to withstand wear and tear, providing long-lasting performance.

How Do You Test The Performance of O-Ring Seals?

Testing the performance of O-ring seals is critical in ensuring they meet the necessary specifications and will perform as expected in the application. There are several tests that can be performed to evaluate the performance of O-ring seals, including the following:

(1)Compression set: The compression set is a test that measures the ability of the O-ring seal to recover its original shape after being compressed. The test is typically performed by compressing the seal to a specific thickness for a specified time and then measuring the percentage of compression set.

(2)Tensile strength: Tensile strength is a measure of the maximum amount of force that can be applied to the seal before it breaks. The test is typically performed by stretching the seal until it breaks and measuring the force required to break it.

(3)Hardness: Hardness is a measure of the seal's resistance to indentation. The test is typically performed by using a durometer to measure the hardness of the seal.

(4)Chemical resistance: Chemical resistance is a measure of the seal's ability to withstand exposure to specific chemicals. The test is typically performed by exposing the seal to a specific chemical for a specified time and then evaluating its appearance and performance.

(5)Temperature resistance: Temperature resistance is a measure of the seal's ability to withstand exposure to high and low temperatures. The test is typically performed by exposing the seal to high and low temperatures and evaluating its performance.

(6)Pressure testing: Pressure testing is a measure of the seal's ability to withstand exposure to high pressures. The test is typically performed by subjecting the seal to a specific pressure and evaluating its performance.

(7)Leakage testing: Leakage testing is a measure of the seal's ability to prevent fluid from passing through it. The test is typically performed by pressurizing the system and monitoring for leaks.
