Aftermarket 403010 Polyamide Hose
This page describes an aftermarket polyamide lubrication hose that cross-references the LUBE 403010, model PH-60. LUBE is a trademark of its respective owner. This is an aftermarket hose, not manufactured, sponsored, or endorsed by LUBE. 403010 designations are for cross-reference identification only. This black polyamide hose is built for high-pressure lubrication lines in industrial lubrication systems, including LUBE EGM pump installations.
Specifications
| Part number | 403010 |
| Model | PH-60 |
| Internal diameter | 4 mm |
| Outer diameter | 8 mm |
| Working pressure | 20 MPa (2,900 psi) |
| Minimum bend radius | 15 mm |
| Material | Polyamide, black |
| Operating temperature | -30 to +80 C |
Flexibility and Routing
The 15 mm minimum bend radius is the standout feature here. It allows tight routing in compact machinery and CNC enclosures where space is limited. A rigid PA12 tube often carries a 50 mm typical bend radius, which quickly becomes a problem when cable carriers, covers, and moving axes leave little room. Cut the hose square and insert it fully into fittings to avoid leaks or blow-offs.
Where This Hose Fits
This hose works in centralized automatic lubrication systems on CNC machines and manufacturing equipment. It connects pump outlets to dividers and metering points, carrying lubricant from the source to each bearing or slide. The 20 MPa working pressure matches LUBE EGM-series pump discharge pressures. For system context, see single-line lubrication system and progressive lubrication systems.
Sizing Notes
The 4 mm ID suits typical lubricant flow for NLGI 2 grease in precision machinery. Before ordering, verify the OD matches your sleeve and ferrule hardware, because a small mismatch can prevent proper assembly. You must also confirm that your fittings grip an 8 mm OD securely before cutting or installing the hose.
When replacing hose inside a machine enclosure, trace the existing run before cutting anything, and note every fitting type along the path. A replacement is fastest when the new hose reuses the same sleeves and nuts, provided they are undamaged. If any sleeve shows scoring or the nut threads feel loose, replace those parts at the same time, because a worn sleeve on new hose is a common source of slow leaks at high pressure.
What to Confirm Before Ordering
Confirm 4 mm ID and 8 mm OD match your fittings. Confirm system pressure within 20 MPa. Confirm temperature range covers your environment. Confirm the length or coil format you need. For pump compatibility and system setup, see grease pump. If you are unsure about fitting style or length, contact the team with your machine details.
Frequently Asked Questions
What pressure can this hose handle?
The hose has a working pressure of 20 MPa. This equals 2,900 psi for lubrication lines.
What size is this hose?
The internal diameter is 4 mm. The outer diameter is 8 mm.
What is the minimum bend radius?
The minimum bend radius is 15 mm. This makes the hose very flexible for tight spaces.
What temperature range does this hose support?
The hose operates from -30 to +80 C. Confirm your environment sits within this range.
What material is this hose made from?
The hose is made from black polyamide. It is suited for high-pressure lubrication lines.
Will it fit my EGM pump?
Check your outlet fitting and 8 mm OD before ordering. Not every EGM configuration uses the same coupling.
Can it carry NLGI 2 grease?
Yes, 4 mm ID suits typical NLGI 2 flow. It works for precision machinery lubrication systems.
What is PH-60?
PH-60 is the LUBE model designation for this hose. The aftermarket part cross-references that model.
What lengths are available?
You should confirm coil or cut length when ordering. The available format depends on your machine layout.
