Hydraulic packing refers to a sealing material used in many machines, valves and pumps in order to stop leakage into or out of the parts. It is made from a variety of materials including cotton, wool, graphite, rubber and PTFE, and the material selected is dependent on the application.

Hydraulic packing is typically used to fill the clearance between a rotating shaft and the bore of the housing surrounding it. The packing is designed to press against the bore and shaft forming a seal, while still allowing rotary motion. It is important to select the correct packing material to ensure an effective seal, while ensuring the operating temperature and speed are suitable for the sealing material.

Hydraulic packing is often used in a variety of pumps, valves and machines to prevent the leakage of fuel, water, and other hazardous liquids or gases. It is also used in the production of pumps, engines and other mechanical applications to provide a strong, reliable seal.

To apply hydraulic packing, the surface of the shaft and housing are cleaned and the packing is placed into the gap between the shaft and the housing. The packing material is then compressed around the shaft and the housing to create a tight seal. It is important to ensure that the hydraulic packing is firmly and evenly compressed to create an effective seal and prevent leakage.

Hydraulic packing is an essential part in the production of a variety of machines, pumps and valves due to the high level of sealing effectiveness it provides. It is important to select the correct material for the application, and to ensure that it is securely and evenly compressed to ensure an effective seal. With the proper selection and application of hydraulic packing, it can provide an effective barrier between two surfaces and help prevent costly leakage.
