Product Overview

The Kobelco High-Pressure Oil Hose Assembly (Drawing Numbers: PS-FB12-736#01, PS-FB12-736#02, and PS-FB12-655) is engineered specifically for Kobelco rotary screw air compressors. Designed to transfer high-temperature synthetic lubricant oil between the oil separator, oil cooler, and air end under continuous high operating pressure.

Built with synthetic rubber inner tubes, high-tensile steel wire braiding, and oil-resistant outer covers, these flexible oil hoses effectively absorb compressor vibration and prevent thermal degradation or fatigue leaks.

Key Features & Benefits

• High Temperature & Oil Resistance: Formulated to withstand continuous oil temperatures and high operating pressure without softening or hardening.

• Vibration Damping: Flexible braided structure absorbs engine and air end vibrations, protecting connecting fittings from stress cracking.

• 100% Direct-Fit Specification: Precision crimped fittings matching Kobelco original thread pitch and sealing angles for a leak-free, plug-and-play setup.

• Extended Operating Life: High-tensile steel reinforcement resists internal pressure surges and external abrasion.

  
  

Technical Specifications

Common Failure Symptoms (When to Replace?)

• Oil Seepage/Leakage at Crimp Joints: Oil weeping around metal ferrule connections due to rubber aging.

• Outer Cover Cracking or Swelling: Softening or hardening of the hose outer layer from heat exposure.

• Abrasive Wear / Wire Exposure: External cover rubbed off due to machine vibration contacting other frame components.
