Flat Rubber Sealing Gasket for Pumps and Valves

Product Features：

1、Excellent Elasticity: This gasket made of rubber material and has excellent elasticity. When fasteners in pumps and valve systems require to be tightened, the rubber gasket, when compressed, use irregular surfaces and microgaps in the elastic filler connectors --forming a seal barrier that prevents media from leaking through the gap and ensures system sealing. This performance is particularly important for sealing fluid Sealed Fluid Direction Control Valves and Mini Sealed Valves because reliable dielectric sealing directly affects operational safety.

2、Effective Shock Absorption & Buffering: Pump and valve systems require frequent reciprocating motion to produce vibration and shock   (e.g. pump operation, valve opening/closing). The gasket has the inherent elasticity and appropriate thickness, can absorb and buffer these vibrations and the energy produced by the impact, plays the role of shock absorbers. shock absorption effect related to the thickness of the gasket: excessive thickness hinders compression   (breaking seal), and too thick will reduce shock absorbers. Our thickness control is accurate up to the micron level, which is more stringent than international standards-ensuring the gasket provide the best shock absorption, which is a key requirement to protect micro-sealed hydraulic pumps and special mechanical components from vibration damage.

3. Excellent temperature resistance: The working temperature of different pump and valve systems varies widely from low temperature to high temperature and high pressure environment. Whether exposed to extreme ambient temperatures or heat from pump/valve reciprocation, gaskets must be able to withstand large temperature ranges --ensuring that the material does not harden, brittle, soften or melt as a result of temperature changes. This durability makes it suitable for Sealed Fluid Transfer Pumps and Sealed Diaphragm Pumps to operate under harsh thermal conditions.

4、Exceptional Corrosion Resistance: pump and valve system to transport a variety of media, including strong acid, strong alkalis, organic solvents and other corrosive substances. The gasket are made of materials that resist erosion by these media, ensuring that they are not damaged by transport media and maintain stable performance over time. This characteristic is indispensable for Equipment-Specific Fittings and Custom Equipment Parts used in chemical fluid transportation applications.

5、Optimal Surface Roughness: The gasket's surface should not be overly rough   (to prevent pores from affecting sealing too much) or too smooth   (to prevent sliding when bolt tightening, affecting installation stability). Proper Appropriate surface roughness facilitates a close connection between the gasket and the connecting surface, improving sealing effectiveness-a key design consideration for Specialized Equipment Accessories and Sealed Fluid Direction Control Valve gaskets.

6、Precise Dimensional Accuracy: The gasket's dimensions must fit tightly with pump and valve system components; excessive dimensional deviation will lead to gaps after installation, impairing sealing performance. Our dimensions are strictly controlled within specified tolerances and meet the precision demands seamless integration of Custom Equipment Parts and Specialty Device Components.

7. Dedicated structural design: Our design of a dedicated gasket structure and pump, valve system connection component structure is a perfect match. In the process of tightening, gaskets can be embedded in the seal to improve the sealing effect. This tailor-made design ensures compatibility with niche mechanical fittings, equipment-specific fittings, and special devices such as Mini Sealed Valves, maximizing sealing reliability when targeted.
