Ferrule For SAE100 R13/ R15 HOSE (External Skive)

FAQs

Q1, What is a Ferrule?

A ferrule is a metal sleeve used in hydraulic hose assemblies to secure the fitting to the hose.

Q2, What is SAE100 R13 and R15?

• SAE 100R13

  • A four or six-spiral steel wire reinforced hydraulic hose.

  • Used for extremely high-pressure applications, such as heavy machinery and industrial hydraulic systems.

• SAE 100R15

  • A six-spiral steel wire reinforced hose (higher pressure rating than R13).

  • Designed for ultra-high-pressure hydraulic systems.

Q3, Why a Special Ferrule for R13/R15?

• R13 and R15 hoses have a thicker outer cover and multi-spiral wire reinforcement, requiring a stronger ferrule with a deep crimping profile.

• The ferrule ensures a secure, high-pressure-resistant connection between the hose and the fitting.

Q4, Why Do SAE 100R13 and R15 Hoses Require External Skiving?

1. Understanding External Skiving

• External skiving means removing the outer rubber cover of the hose before crimping the ferrule.

• This process exposes the steel wire reinforcement layer, allowing for better crimping and grip between the ferrule and the hose.

2. Why Skive R13 & R15 Hoses?

• R13 and R15 hoses are multi-spiral steel wire reinforced hoses with a thick outer rubber layer.

• If the ferrule is crimped over the unskived outer cover, the rubber may compress unevenly, reducing crimping effectiveness.

• External skiving improves the bite of the ferrule, ensuring a secure, high-pressure connection.

3. Benefits of External Skiving

✅ Better Grip & Retention – The ferrule grips directly onto the steel wire reinforcement, preventing slippage.
✅ Leak Prevention – Ensures a tighter and more secure crimp for high-pressure applications.
✅ Stronger Connection – Essential for ultra-high-pressure hydraulic systems that use R13/R15 hoses.
