Overview
This Demco DM05982 hydraulic brake hose is a flexible 19" brake line component used between the hydraulic brake actuator line and the trailer brake lines. It features a straight hose design with male and female inverted fittings, making it a practical replacement hose for compatible hydraulic drum or disc brake systems where length, fitting style, and routing match.
R&P Service Insight
Hydraulic brake hoses are small parts that do important work. A worn, cracked, kinked, or mismatched hose can affect brake response and create service issues in the trailer braking system.
- Measure First: Confirm the original hose length and routing before ordering.
- Check Fittings: Verify male/female orientation and 3/16" fitting compatibility.
- Inspect the System: Replace hoses showing cracking, swelling, leaks, corrosion, or damaged fitting threads.
R&P Knowledge Hub
Compatibility: Designed for hydraulic trailer brake systems using a 18-7/8" flexible hose with 3/16" male and female inverted fittings.
Vehicle / System Fit: Commonly used on Demco Kar Kaddy tow dolly hydraulic brake applications where the original hose length and fitting configuration match.
Installation Notes: Verify hose length, routing clearance, fitting style, thread condition, and brake system type before installation. Brake lines should be properly bled after service.
Performance Insight: A flexible hose section helps absorb movement between fixed brake lines and moving trailer components while maintaining hydraulic brake pressure transfer.

R&P Repair Insight
When replacing a hydraulic brake hose, do not rely on length alone. The hose must match the correct fitting style and must route without stretching, twisting, rubbing, or kinking through the full range of trailer movement.
- Length Check: Listed as 18-7/8" to 19" long; compare against the hose being removed.
- Fitting Check: Includes 3/16" e-coated steel inverted male and female fittings.
- Safety Check: Inspect surrounding brake lines, actuator connections, and caliper or wheel cylinder lines during replacement.
