LUBE 403001 Hose Sleeve
The LUBE 403001 is model PH-N, a hose sleeve for LUBE high-pressure hose assemblies. It forms the hose end connection used on centralized lubrication systems. The sleeve compresses onto the hose end together with a hose stud to create the reusable connection.
Official Dimensions and Thread
- Thread: M6x0.75
- Material: iron
- Overall length L: 28 mm
- Diameter D: 11.7 mm
- L1: 21 mm
- L2: 5 mm
- D1: 10 mm
- Size across flats B: 12 mm
The same official LUBE table lists PH-NB as a companion sleeve model in this family.
Sleeve, Stud, and Assembly Torque
The sleeve and hose stud compress onto the hose end together to form the reusable hose-end connection used on LUBE lubrication lines. The assembly tightening torque is 80 to 90 kgf-cm, about 7.8 to 8.8 N-m. This torque applies when tightening the hose sleeve and hose stud during assembly, not to the sleeve alone.
The Companion Hose: 403010 PH-60
The companion hose for this sleeve is LUBE 403010, model PH-60. See the 403010 high-pressure hose page for full details.
- Outer diameter: 8.3 mm
- Inner diameter: 3.6 mm
- Working pressure: 20 MPa, 200 bar
- Burst pressure: 72 MPa
- Minimum bending radius: 15 mm
- Material: polyamide
- Color: black
- Standard supply length: 100 m
Some commercial listings round the hose to 4 mm ID x 8 mm OD. The official LUBE table gives 3.6 mm inner diameter and 8.3 mm outer diameter as the reference values. The 20 MPa working pressure rating belongs to the hose specification, not to the sleeve.
Where the Sleeve Fits
Hose assemblies carry lubricant from the pump to metering points in single-line lubrication systems and similar configurations. The sleeve-and-stud end can be re-made when a hose is shortened, using a new sleeve. This is an aftermarket sleeve, not manufactured, sponsored, or endorsed by LUBE Co., Ltd. For fit confirmation, contact the quotation team.
Ordering Practice
Confirm the hose size and stud part at quotation before ordering. Order sleeves together with the matching studs to avoid assembly mismatch. Verify the M6x0.75 thread against the pump or junction port before finalizing. Request the current LUBE assembly instructions for the correct torque procedure.

What hose does it fit?
It fits the LUBE 403010 hose, model PH-60. The hose has an 8.3 mm outer diameter and a 3.6 mm inner diameter.
What are the sleeve dimensions?
The sleeve dimensions are L 28 mm, D 11.7 mm, L1 21 mm, L2 5 mm, D1 10 mm, B 12 mm. These values come from the official LUBE table.
What torque applies to assembly?
The assembly torque is 80 to 90 kgf-cm, about 7.8 to 8.8 N-m. This applies to the sleeve and stud together during assembly.
What pressure does the sleeve handle?
The 20 MPa working pressure rating belongs to the hose specification. The official sleeve listing is dimensional and does not state a pressure rating.
Is the hose really 4 mm by 8 mm?
Commercial shorthand sometimes says 4 by 8 for convenience. The official values are 3.6 mm inner diameter and 8.3 mm outer diameter.
What is PH-NB?
PH-NB is a companion sleeve model in the same official LUBE family. It appears alongside PH-N in the LUBE documentation table.
What is the burst pressure of the hose?
The burst pressure of the companion hose is 72 MPa. This value comes from the official LUBE hose table.
Can the hose end be re-made?
Yes, the sleeve and stud form the reusable hose end. Use a new sleeve when re-making the connection.
