HP Seal kit | Intensifier | 60K | HJ-001198-1
The HJ WATERJET HP Seal Kit, Intensifier, 60K (HJ-001198-1 or HJ-302004-1) is a precision-engineered high-pressure seal rebuild kit designed to restore the water-side sealing system of intensifier pumps operating up to 60,000 PSI (4,100 bar).
The HJ-001198-1 or HJ-302004-1 HP Seal Kit targets the most critical sealing interface in the pump—the dynamic sealing area around the ceramic plunger (rod pack)—where extreme pressure, friction, and heat cause progressive wear. Over time, these hp seals degrade, leading to pressure loss, leakage, and reduced cutting performance.
The HJ-001198-1 or HJ-302004-1 HP Seal Kit provides all essential sealing elements required to rebuild that interface and return the intensifier to peak operating efficiency, without the cost or downtime of a full pump overhaul.
The HJ-001198-1 or HJ-302004-1 include the following parts:
HJ-004406-1 or HJ-100053-1 Intensifier High Pressure Seal, 60K (4)
HJ-004407-1 or HJ-100054-1 Intensifier Seal Hoop, 60K (4)
HJ-B-8075-119 or HJ-400042-119-80 O-Ring (4)
HJ-B-1465-1 or HJ-100021-1 Intensifier Backup Seal Ring, Bronze, 60K (2)
Key Benefits
- Restores Full Operating Pressure – Eliminates internal leakage

- Prevents Costly Downtime – Quick rebuild vs full overhaul
- Optimized Seal Geometry – Designed for high-cycle durability
Applications
- Industrial waterjet cutting systems
- Automotive manufacturing (robotic cutting & trimming)
- Aerospace fabrication
- Metal, stone, and composite cutting
- High-production waterjet facilities
Frequently Asked Questions
1. What is HJ-001198-1?
HJ Waterjet HJ-001198-1 is a direct replacement for FLOW 001198-1
2. What pressure is HJ-001198-1 rated for?
It is designed for 60,000 PSI (60K) waterjet intensifier applications.
3. What pump does HJ-001198-1 fit?
It is associated with FLOW 60K ESL intensifier pumps and FLOW-style 60K high-pressure cylinders.
4. When should I replace the HJ-001198-1 seal kit?
Typical indicators include high-pressure water leakage, difficulty maintaining pressure, pressure fluctuations, reduced cutting performance, or worn/damaged high-pressure seals.
5. Can I buy an equivalent replacement for FLOW 001198-1?
Yes. HJ Waterjet lists HJ-001198-1 as a 60K high-pressure seal kit cross-referenced to FLOW 001198-1, as well as HJ-302004-1 for the H2O Jet cross-reference.
6. Is FLOW 001198-1 the same as H2O Jet 302004-1?
They are commonly cross-referenced as equivalent 60K high-pressure seal kits for compatible intensifier applications.
