004014SH Hose Ferrule for R12 Spiral Hose

The 00401 4SH hose ferrule is a one-piece crimp sleeve engineered for large-bore 4SH and R12 spiral-wire hydraulic hoses. It covers three heavy-duty dash sizes, 20, 24, and 32 (DN 32, 40, and 50), with ferrule lengths up to 78 mm. This page lists every dimension, material spec, crimping requirement, and ordering detail you need to spec the right part for your high-pressure line.

What Is the 00401 4SH Hose Ferrule?

A 4SH hose ferrule is the outer metal shell of an ultra-high-pressure hose fitting. Spiral-wire hoses carry the heaviest loads in hydraulics, so the ferrule must grip through the hose cover and hold the joint under extreme pressure and impulse cycles. The 00401 ferrule meets that demand with multiple annular serrations on the inner bore that lock into the hose reinforcement during crimping.

This 4SH hose ferrule is designed for 4SH (EN 856) and R12 (SAE 100 R12) hoses in the large bore range, the same family used on the biggest excavators, drilling rigs, and mining machines. Each part is machined to a tight outer diameter tolerance so crimp results stay consistent from batch to batch.

Core advantages:

• Built for large-bore 4SH and R12 spiral hoses, dash 20 to 32
• Annular serrations lock into the hose reinforcement for maximum grip
• Tight O.D. tolerance for repeatable crimp results
• Ultra-high-pressure service on excavators, drilling, and mining equipment
• One-piece crimp design for permanent, leak-free joints
• Zinc plating standard; stainless steel for corrosive service

Key Specifications and Dimensions

All 00401 ferrules share one cylindrical, hollow-body geometry with continuous annular serrations on the inner bore. Length (L) is the primary 4SH hose ferrule dimension, matched to each hose dash size.

• Length tolerance: ±0.5 mm across the range
• Outer diameter tolerance: ±0.1 mm for consistent crimping results
• Coverage note: for 4SH dash 12-16 and R12 dash 06-16, use our 00400 series; this 00401 series covers the larger sizes, dash 20 to 32

Applicable hose types: EN 856 4SH and SAE 100 R12 four-spiral-wire hoses with standard cover dimensions.

Crimp diameter note: the final crimped O.D. is set by your hose maker’s crimp chart, not by the ferrule alone. Always verify the target crimp diameter against the hose manufacturer’s published chart before production runs.

Material and Surface Finish

• Base material: carbon steel, cold formed for uniform grain structure
• Surface treatment: yellow zinc plating with yellow chromate passivation
• Corrosion resistance: typical neutral salt spray performance ≥120 h per ISO 9227; zinc-nickel available for offshore service
• Hardness: balanced to resist cracking during crimping, typically HRC 20-25; certified values on request
• Inner bore: continuous annular serrations for maximum grip on spiral hoses

We also supply this 4SH hose ferrule in stainless steel for corrosive and high-temperature service on request.

Performance and Crimping Requirements

Working pressure follows the hose standard and your hose maker’s data sheet: EN 856 4SH for 4SH hoses and SAE 100 R12 for R12 hoses. We confirm the applicable working pressure for your dash size on request, and the ferrule is designed to hold the assembly to the hose’s rated performance.

• Temperature range: -40 °C to +100 °C for 4SH and -40 °C to +121 °C for R12 service; confirm with your hose manufacturer
• Crimping type: one-piece crimp; the 00401 4SH hose ferrule works with standard hydraulic crimping machines and matching die sets
• Hose preparation: 4SH and R12 assemblies typically require cover removal (skiving) before crimping; follow your hose manufacturer’s preparation instructions
• Reuse: ferrules are single-use components. Never re-crimp a used ferrule.

Application Guide: Built for Heavy-Duty Spiral Service

We are transparent about where this product fits. Large-bore 4SH and R12 hose assemblies with 00401 ferrules are built for the heaviest hydraulic duties: excavators, drilling rigs, mining machinery, and high-pressure industrial systems. They are not a light-industrial component, and they are not interchangeable with braided-hose ferrule series.

If you are unsure whether your application needs 4SH, R12, or a lighter family, send us your working pressure, hose size, and duty cycle, and our engineers will recommend the right hose family and ferrule series before you order.

Installation Guide

1. Cut the hose square with a sharp hose cutter. A square cut prevents leakage paths and uneven grip.
2. Prepare the hose end per your hose maker’s instructions. For 4SH and R12 hoses, this normally means removing the cover (skiving) to the specified length.
3. Insert the matching stem fully into the hose bore.
4. Slide the 00401 ferrule over the prepared hose end and seat it against the stem shoulder.
5. Position the assembly in the correct die set and crimp to the target crimp diameter.
6. Verify the crimp O.D. with a caliper. Record the value for quality traceability.

Matching components: the 00401 ferrule pairs with the matching 00401-series stem (insert) from the same fitting family. We supply ferrule and stem as matched sets, which is the recommended way to achieve consistent, certified assemblies.

How to Select the Right Ferrule Size

Selecting the right 4SH hose ferrule size starts with the hose family and the dash size.

• Step 1: Confirm the hose family: EN 856 4SH or SAE 100 R12.
• Step 2: Match the dash size to the hose I.D. (20 = DN 32, 24 = DN 40, 32 = DN 50).
• Step 3: For smaller spiral sizes (4SH dash 12-16, R12 dash 06-16), use our 00400 series.
• Step 4: Cross-check the target crimp diameter on your hose maker’s crimp chart.

When in doubt, send us the hose brand, standard, dash size, and crimp machine model. Our engineers will confirm the correct 00401 part number and crimp data before you order.

Quality Control and Testing

• Dimensional inspection with calibrated gauges on every 4SH hose ferrule batch
• Batch salt spray testing to verify plating quality
• Pull-off and burst testing on sample assemblies to validate grip performance
• Batch traceability marking on packaging

Warranty and honesty: we guarantee workmanship and material defects and replace defective parts without question. Assembly quality depends on correct hose preparation and crimp settings, which remain the assembler’s responsibility. We share crimp data openly and support you through first articles.

FAQ

Q: Which hose does the 00401 4SH hose ferrule fit? A: Four-spiral-wire hoses to EN 856 4SH or SAE 100 R12 in dash sizes 20 to 32 (DN 32 to 50).

Q: What is the difference between the 00400 and 00401 series? A: The 00400 series covers 4SP across the full range plus 4SH dash 12-16 and R12 dash 06-16. The 00401 series covers the large 4SH and R12 sizes, dash 20 to 32.

Q: Is this ferrule skive or no-skive? A: For 4SH and R12 hoses, cover removal (skiving) is typically required before crimping. Follow your hose manufacturer’s preparation instructions.

Q: What pressure can these assemblies handle? A: The rating follows the hose standard: EN 856 4SH or SAE 100 R12. Confirm the working pressure for your dash size with our engineers.

Q: Can the ferrule be reused after a hose fails? A: No. Hydraulic ferrules are single-use components. Always crimp a new ferrule for every new assembly.

Q: Do you provide samples and custom finishes? A: Yes. Sample kits, stainless steel, zinc-nickel plating, and private label options are all available.
