Combination Sealing Washer: complementary advantages, better sealing effect

Metric High-Pressure-Rated Metal-Bonded Sealing Washers in various mechanical equipment in an important role.

Metric High-Pressure-Rated Metal-Bonded Sealing Washers with the rubber ring and metal ring whole bonding vulcanization are used to seal the thread and flange connection sealing ring; the ring includes a metal ring and a rubber gasket. The metal ring is rust-proof, and the rubber ring is generally made of oil-resistant nitrile or fluorine rubber. A combination of pads has two sizes: metric and imperial. There is a standard JB982-77 that provides for the combination of pads of metal pads plus rubber in the form of a combination.

What is a combination sealing washer? Classification of combination sealing washers?

A combination seal comprises two or more different materials designed to achieve complementary advantages and improve the sealing effect. Seal combinations can be categorized according to their composition and structural form. The more common combinations are metal-rubber combination sealing washers, PTFE-rubber combination sealing washers, and so on.

The combination of sealing gaskets can be divided into A-type and B-type according to the form of structure; the different rubber packages can be split into complete and half packages. Once damaged, it often leaves a tremendous hidden danger to the sealing part; even if never used, leakage may occur. Select the correct specifications of the washers; metal washers are generally not easily damaged when producing a combination of washers, and rubber washers will be regularly viewed and replaced. Be sure to select the correct specifications of the rubber washers; do not exist in a fluke. Choose a slightly smaller or larger rubber washer. The more common comb nations are metal-rubber combination sealing washers, PTFE-rubber combination sealing washers, and so on. There are the following types of combination sealing washers:

Application scenarios for Metric High-Pressure-Rated Metal-Bonded Sealing Washers

The metal washer in the Metric High-Pressure-Rated Metal-Bonded Sealing Washers ensures the components are reliably connected and securely fastened. The thickness of the retaining ring limits the compression of the elastomer seal, eliminating the phenomenon of exceeding the limiting torque at the union and, therefore, ensuring a reliable sealing system. It is generally used with ferrule fittings. The metal ring will be rust-proofed to prevent leakage of oil, fuel, water, pharmaceuticals, etc., and the rubber ring is generally made of oil-resistant nitrile rubber or viton rubber. Because of its simple structure, high sealing efficiency, and low price, it is widely used in the machinery manufacturing industry. Metric High-Pressure Rated Metal-Bonded Sealing Washers for threaded pipe fittings and screw plug sealing it is generally used together with the ferrule type pipe fittings used to plug the oil port, mainly used for hydraulic valve pipe fittings threaded connections at the end of the static sealing, applicable to the British, American standard inch threads and the French, German standard metric thread connections at the end of the static sealing and so on.

Metric High-Pressure-Rated Metal-Bonded Sealing Washers are widely used in automobiles, aviation, machinery, the chemical industry, and other fields. For example, in the automotive field, a combination of seals can be used in the engine, transmission, hydraulic system, and other vital parts, and they play wear-resistant, corrosion-resistant, noise-reduction, and other roles. In machinery, combined seals can be used in high-precision machine tool oil seals, water seals, etc., to ensure the regular operation of the equipment.

Matters concerning the use of Metric High-Pressure-Rated Metal-Bonded Sealing Washers

In replacing the Metric High-Pressure-Rated Metal-Bonded Sealing Washers, we must pay special attention to the following matters.

1. Do not force the installation of seals. Some seals need to be placed in the groove and then need to be tightly fitted. The operation should be careful and slowly loaded, not brute force, which is vast and forced to load. Otherwise, it will damage the seals and cannot play the role of proper sealing.

2. When installing, the balance and symmetry must be grasped, and the seals are placed parallel to the established influential sealing surface position. Further observation found leakage in time to re-installation to avoid leakage in the production process and lead to production interruptions.

3. Do not damage the rubber ring sealing surface or sealing line. The sealing performance of the plane seals relies on the upper and lower two end faces; if damage occurs, it will lead to leakage; the rubber ring is made of soft and elastic rubber, plastic, fibers, and other unique materials, and therefore need to be in the handling, installation, maintenance process, pay attention to the scratching, abrasion, bumping and so on.

The development trend of Metric High-Pressure-Rated Metal-Bonded Sealing Washers

With the development trend of intelligence and green environmental protection, the combination seal ring will develop in the direction of high performance, environmental protection, and intelligence. For example, nanoscale materials, intelligent materials, etc., can be used to improve the performance of the combination seal ring and simultaneously reduce environmental pollution in the production process.

As a form of sealing with complementary advantages, the combination seal has various application prospects in multiple fields. With the continuous progress of science and technology, the performance of the combination seal will be further improved to provide better sealing protection for mechanical equipment.
