How to choose V-Packings

Points to check when selecting, with the values for this product (K1012-M).

1. 1. Match shaft and groove dimensions

   Inner diameter d corresponds to the shaft (rod) diameter, and outer diameter D corresponds to the groove diameter. V-ring packings seal through lip compression allowance, so dimensional mismatch leads to leakage, excessive friction, and early wear. When replacing, measure the actual housing and shaft dimensions and tolerances rather than relying on the existing part, and verify against them.

2. 2. Check stack height and groove depth

   Height H is the dimension when stacked including adapters and must match the axial length of the groove (packing chamber). If the height does not match, the gland cannot be tightened properly; under-tightening causes leakage, and over-tightening causes heat generation and increased sliding resistance.

3. 3. Select a stack configuration suited to operating pressure

   This product: Maximum Operating Pressure 500 bar

   V-ring packings can handle higher pressures as the number of rings increases. The maximum operating pressure of listed products is indicated as 500 to 600 MPa, but this value is conditional. Confirm the actual continuous and surge pressures, along with the ring count and adapter configuration, in the manufacturer's documentation.

4. 4. Select materials suited to fluid and temperature

   NBR suits mineral-based hydraulic oils, FKM suits high temperatures and chemical resistance, fabric-reinforced rubber suits high pressure and wear resistance, and PTFE suits low friction and broad chemical resistance. Confirm material compatibility with both the applied fluid, such as hydraulic oil, water, or chemicals, and the operating temperature range.

5. 5. Observe the maximum sliding speed

   This product: Maximum Sliding Speed 0.5 m/s

   V-ring packings have a large contact area and tend to generate frictional heat, so they are not suited to high-speed reciprocating motion. The maximum sliding speed of listed products is 0.5 m/s. Applications exceeding this speed will accelerate degradation from heat, so verify stroke speed and consider other seal types.

6. 6. Consider guide accuracy and installation conditions

   Where guiding is insufficient and the shaft runs out, or housing tolerances are large, types with flexible lips tend to follow the motion more easily. Select a type suited to the installation environment, including ease of disassembly and replacement and whether gland tightening adjustment is possible.
