We're mainly engaged in the research, manufacturing, and selling of seals for a variety of businesses, for example, piston seals, rod seals, symmetric seals, rotary seals, food-grade oil seals, pneumatic and hydraulic seals, engineering machinery seals, oil seals, coal mining seals, compact seals, wear strips, guide rings, PTFE seals, spring energized seals, PU seals, wiper seals and so forth. We will create pre-assembled seals based on clients' samples or samples.

We've got the ISO9001 certificate. Together with the fully licensed and automatic manufacturing supplies and also a group of professionals, we're a respectable manufacturer from the manufacturing industry. DSH Seals features a very long record of developing unique and advanced tech solutions. Our oil seals, hydraulic seals, and PTFE seals are the most well-known in China market. The durability, flexibility, and durability would be the benefits offered with these seals to get various industrial uses, such as electrical, machines, petroleum & petrol refinery, chemical, electronics appliances, etc. In any case, you can find more than 1, 000 types of seals designed for a variety of applications. Every specified utilization of seals might be customized just by the R&D team. The team is likely to make the proper seals for clients carrying the topics of lubricant, concentricity, rotating rate, temperature, pressure, and bore tolerances. This excellency lets them be much more elastic from the markets no matter in products or technology.

Seals are essential in terms of process stability, machine or device safety, and economic viability. Oil seals can be used in all hydraulic systems, pumps, pistons, pipe connections, etc. The seals play a crucial role in all rotating and moving part assembly as they act as a physical barrier to retain lubricants while excluding dirt, moisture, and other contamination. Oil seals can be used in the aerospace, automotive, appliances, marine, medical, military industries. More specific applications include motors, pumps, bearings, extruders, valves, compressors, spindles, gearboxes, etc. Also, the oil seal can be used to seal around the rotating shaft and maintain an oil-based lubricant inside the shaft, engine, etc.

The oil seals, more specifically, the dynamic oil seals, can protect the automotive engines. The dynamic oil seals are usually constructed from a rope packing or synthetic rubber. Usually, the seals can stand more shaft eccentricity and load and can operate at higher shaft speeds; hence, they have a better sealing performance and better protect the automotive engines. Our oil seals for automotive engines have high-temperature flexibility. The seals are designed with different temperature resistance level depending on the engine types and location within the engine. For example, the rear crankshaft seal is designed with higher temperatures of withstanding capability than the front seal. Of course, DSH Seals has customized seals for industries such as engineering machinery, oil & natural gas, intelligent manufacturing, new energy industries, and so on.
