03310 Hose Ferrule for SAE 100 R2AT/EN 853

The 03310 2SN hose ferrule is a one-piece, no-skive crimp sleeve engineered for SAE 100 R2AT and EN 853 2SN two-wire-braid hydraulic hoses. It covers eight standard dash sizes from 03 to 16 (DN 5 to 25) and holds assemblies at working pressures up to 400 bar. This page lists every dimension, material spec, crimping requirement, and ordering detail you need to select the right part with confidence.

What Is the 03310 2SN Hose Ferrule?

A 2SN hose ferrule is the outer metal shell of a high-pressure hydraulic hose fitting. Two wire braids demand higher grip force than single-braid hoses, so the ferrule must transfer more crimp load without slippage. The 03310 ferrule meets that demand with precision-formed serrations on the inner bore that bite into the hose cover.

This 2SN hose ferrule uses a no-skive design, so the hose cover stays intact during assembly. Our in-house tests show that correctly crimped 03310 assemblies hold beyond the hose’s rated working pressure without leakage or fitting pull-out, even under repeated impulse cycles.

Core advantages:

• High-pressure performance: working pressures up to 400 bar per EN 853 2SN
• Leak-free and pull-off-resistant joints under pressure and impulse loads
• No-skive design: skip the skiving step and cut assembly time
• Serrated inner teeth grip the hose cover evenly around the full circumference
• Yellow zinc plating protects against corrosion in humid and outdoor service
• One part family covers dash sizes 03 to 16, simplifying inventory

Key Specifications and Dimensions

All 03310 ferrules share one cylindrical, hollow-body geometry with annular serrations on the inner bore. Length (L) is the primary 2SN 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
• Designed for hoses whose cover O.D. conforms to EN 853 2SN / SAE 100 R2AT

Applicable standards: SAE J517 (100 R2AT), EN 853 (2SN), and dimensionally aligned with ISO 1436 Type 2SN.

Crimp diameter note: the final crimped O.D. is set by your hose maker’s crimp chart, not by the ferrule alone. The tight O.D. tolerance of the 03310 ferrule keeps crimp results stable from batch to batch. 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 plating available for offshore or high-corrosion service
• Hardness: balanced to resist cracking during crimping, typically HRC 20-25; certified values available on request
• Inner bore: precision-formed serrations for maximum grip without damaging the hose cover

For food, pharmaceutical, or highly corrosive media, we also supply this 2SN hose ferrule in stainless steel on request.

Performance and Crimping Requirements

Working and burst pressure values below follow EN 853 2SN / SAE 100 R2AT for the assembled hose. The ferrule is designed to hold the assembly to the hose’s rated performance.

• Temperature range: -40 °C to +100 °C for continuous service
• Crimping type: no-skive, one-piece crimp
• Equipment: the 03310 2SN hose ferrule works with standard hydraulic crimping machines and standard die sets
• Reuse: ferrules are single-use components. Never re-crimp a used ferrule.

Installation Guide

1. Cut the hose square with a sharp hose cutter. A square cut prevents leakage paths and uneven grip.
2. Measure and mark the insertion depth on the hose cover.
3. Insert the matching stem fully into the hose bore.
4. Slide the 03310 ferrule over the 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 03310 ferrule is designed to pair with the matching 03310-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 2SN hose ferrule size starts with the dash size.

• Step 1: Match the dash size to the hose I.D. (03 = 5 mm, 04 = 6 mm, and so on).
• Step 2: Confirm the hose cover O.D. sits within EN 853 2SN / SAE 100 R2AT tolerance.
• Step 3: Cross-check the target crimp diameter on your hose maker’s crimp chart.

When in doubt, send us the hose brand, dash size, and crimp machine model. Our engineers will confirm the correct 03310 part number and crimp data before you order.

Quality Control and Testing

• Dimensional inspection with calibrated gauges on every 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 we replace defective parts without question. Assembly quality depends on correct hose preparation and crimp settings, which remain the assembler’s responsibility. We share our crimp data openly and support you through first articles.

よくある質問

Q: Which hose does the 03310 ferrule fit? A: Two-wire-braid hoses manufactured to SAE 100 R2AT, EN 853 2SN, or ISO 1436 Type 2SN with a standard cover O.D.

Q: What is the difference between 1SN and 2SN ferrules? A: 2SN ferrules are built for two-wire-braid hoses with higher pressure ratings (up to 400 bar in small sizes, versus 250 bar for 1SN). The two series are not interchangeable: always match the ferrule series to the hose construction.

Q: Is this a skive or no-skive 2SN hose ferrule? A: No-skive. The serrated inner bore grips the intact hose cover, so no skiving is required.

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: What crimp diameter should I use? A: Use the target crimp diameter from your hose manufacturer’s crimp chart for the specific dash size. We provide reference crimp data with every order.

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