Helical Spring Seals Series
HS003 – External Pressure Piston Seal (Static Gas & Vacuum Sealing)
Designed with an outward-facing sealing profile, this piston seal is optimized for external pressure sealing applications. It is suitable for static sealing in gas, refrigerant, and vacuum environments.
The structure allows external pressure to reinforce the sealing contact, improving reliability and resistance to leakage. It is widely used in systems where pressure is applied from the outside of the sealing interface.
| Types | SEAL ID(mm) | Pressure(Mpa) | Temperature(℃) | Linear velocity(m/s) |
|---|---|---|---|---|
| Static seal | 3~2200(.118-86.614) | ≤20 | -200~320 | 0 |
HS007 – High Pressure External Face Seal (≤70 MPa)
Designed with an externally reinforced face sealing geometry, this seal is suitable for high-pressure applications up to 70 MPa.
It is used in systems where pressure is applied externally, requiring a robust structure to maintain sealing contact. The design improves stability under fluctuating pressure conditions and reduces the risk of leakage.
| Types | SEAL ID(mm) | Pressure(Mpa) | Temperature(℃) | Linear velocity(m/s) |
|---|---|---|---|---|
| Static Seal | 3~2200(.118-86.614) | ≤80 | -200~320 | 0 |
HS009 – Ultra High Pressure External Face Seal (≤120 MPa)
Designed for ultra-high pressure external sealing conditions, this seal provides reliable performance up to 120 MPa.
It is suitable for critical systems where external pressure dominates and sealing failure is not acceptable. The reinforced geometry ensures durability and consistent sealing performance under extreme loads.
| Types | SEAL ID(mm) | Pressure(Mpa) | Temperature(℃) | Linear velocity(m/s) |
|---|---|---|---|---|
| Static Seal | 3~2200(.118-86.614) | ≤120 | -200~320 | 0 |
