Description
45° Graphite Self-Sealing Packing Ring
The JT-RG730 self-sealing packing ring uses pure flexible graphite paper, cut and spirally wound before compression moulding into a ring with a 45° bevel. Also described as a self-tightening graphite packing ring, it can seal the upper and lower end faces of a stuffing box or be specified for use as a separate set.
Contact IKSONIC in China for wholesale supply and factory sourcing of graphite sealing rings to your required dimensions. Special sizes and non-standard profiles can be discussed against customer requirements or samples.
Construction and Profile Options
- Pure flexible graphite paper construction with a moulded 45° beveled profile.
- Metal edging or corner wrapping on the upper and lower end faces can be specified to customer requirements.
- The source listing title also refers to V-shaped/wedge profiles and wire-mesh reinforcement. Confirm the required profile, reinforcement and metal material for the ordered construction; these are not presented as standard features of every JT-RG730 ring.

Self-Sealing Ring Technical Data
| Parameter | Source table value |
|---|---|
| Temperature | −200 to 450 °C |
| Temperature in non-oxidizing media | −200 to 800 °C |
| Pressure | ≤35 MPa |
| pH range | 0–14 |
| Linear speed | 10 m/s |
These values reproduce the source technical table for self-sealing graphite packing rings. They are not independently verified ratings or a statement that the temperature, pressure and speed values can be used together at their limits. Confirm the selected ring construction and actual service conditions before ordering. The 800 °C upper value applies only to non-oxidizing media.

The source series table gives 1.25–2.0 g/cm³ in a shared density cell. It does not provide separate density values for each model or establish that every model is offered throughout that range. The related series are references, not items included in a complete kit, and the self-sealing-ring technical data above should not be assumed to apply to every series.
Applications and Media
The source describes sealing applications in valves and pumps, including the 45° beveled self-tightening seals used in power systems. Suggested sectors include petroleum equipment, power plants, chemical processing and steel plants, particularly locations involving high temperature or pressure.
Listed media include hot water, high-temperature/high-pressure steam, heat-transfer media, hydrogen, ammonia, organic solvents, hydrocarbons and low-temperature liquids. Certain strongly oxidizing media are excluded. This list and the stated pH range are not blanket chemical-compatibility approval; confirm the medium, concentration and operating conditions for the specified construction.
Ordering and Wholesale Enquiries
For a quotation, provide the required inside diameter, outside diameter, height, profile and bevel details, quantity, medium, temperature, pressure and motion conditions. State whether wire-mesh reinforcement, metal edging or corner wrapping is needed, together with the required metal grade. The listed Φ15–Φ1000 mm range does not define either an inside-diameter or outside-diameter range.
The gallery includes a single-ring view, stacked-ring examples and an assortment of ring and cut-profile examples. The assortment does not identify every item as JT-RG730 and does not show a defined kit or order quantity.
