40K High Pressure Cylinder | HJ-100001-2


The HJ-100001-2 High Pressure Cylinder is a 40,000 PSI high-pressure cylinder designed for H2O Jet waterjet intensifier systems. It is a critical component of the high-pressure section of the intensifier, helping convert hydraulic power into the ultra-high-pressure water required for precision waterjet cutting applications. It is identified as the 40K high-pressure cylinder and replaces the earlier 007038-2 part number.

The cylinder threads are pre-coated to help reduce galling during assembly and service. However, anti-seize is still required during installation. Following the recommended assembly procedure is important for protecting the threads and helping ensure reliable service.

 

Key Benefits

HJ-100001-2 40K HP cylinder is part of the 40K short-block intensifier assembly. Related 40K components include the HJ-100018-2 Backup Sleeve and HJ-302004-2 High-Pressure Seal Kit

 

Pre-Coated Threads – Blue Anti-Seize Still Required

The HJ-100001-2 High Pressure Cylinder features pre-coated threads intended to help reduce galling during assembly.

Important installation note: The pre-coating does not eliminate the need for anti-seize. Anti-seize is still required when installing the cylinder.

Always follow the applicable installation and maintenance procedures for your specific intensifier configuration.

Is HJ-100001-2 a 40K or 60K Cylinder?

The HJ-100001-2 is the 40K cylinder.

Documentation identifies:

  • HJ-100001-2 = 40K High Pressure Cylinder
  • HJ-100001-1 = 60K High Pressure Cylinder

 

Extreme Flow (EF) Compatibility Note

Important: The Extreme Flow (EF) version is intended for the special, larger H2O Jet intensifier.

The EF configuration is designed around the larger intensifier and produces approximately 1.5 GPM from a single intensifier.

Do not assume a standard 40K cylinder and an Extreme Flow cylinder are interchangeable. Verify the required configuration against the intensifier before purchasing.

 

Frequently Asked Questions

What is HJ Waterjet Jet part number HJ-100001-2?

HJ-100001-2 is a direct replacement for H20 100001-2 40,000 PSI high-pressure cylinder used in compatible H2O Jet waterjet intensifier systems

What pressure is the HJ-100001-2 rated for?

The HJ-100001-2 is the 40K high-pressure cylinder, intended for 40,000 PSI waterjet applications.

What does HJ-100001-2 replace?

The HJ-100001-2 is listed as replacing 007038-2.

Is HJ-100001-2 the same as HJ-100001-1?

No. HJ-100001-2 is the 40K cylinder, while HJ-100001-1 is the 60K cylinder. They are different pressure configurations and should not be treated as interchangeable without confirming equipment compatibility.

Does the HJ-100001-2 cylinder have pre-coated threads?

Yes. The HJ-100001-2 High-Pressure Cylinders have pre-coated threads to help reduce galling.

Do I still need Anti-seize?

Yes. Anti-seize is still required. The pre-coated threads are intended to help reduce galling, but they do not eliminate the need for the specified anti-seize during installation.

What is the H2O Jet Extreme Flow cylinder?

The Extreme Flow (EF) version is intended for H2O Jets special larger intensifier. This configuration produces approximately 1.5 GPM from a single intensifier.

Does HJ-100001-2 work with the Extreme Flow intensifier?

You should verify the exact intensifier configuration before ordering. The Extreme Flow configuration uses the larger special intensifier, and H2O Jet documentation identifies separate 1.5-GPM components.

What seal kit goes with HJ-100001-2?

The related 40K high-pressure seal kit is HJ-302004-2.

What backup sleeve is used with HJ-100001-2?

The corresponding 40K backup sleeve is HJ-100018-2.

Can I use a HJ-100001-2 in place of a 60K cylinder?

No—not simply because the physical component may appear similar. The HJ-100001-2 is specifically the 40K cylinder, while HJ-100001-1 is the 60K version. Confirm the pressure rating and intensifier configuration before installation.
