Parker 387-4-RL Hydraulic Hose 0.25in Id 3000 Psi

Product Description

The PARKER 387-4-RL is a synthetic rubber hydraulic hose rated for 3,000 psi working pressure. With a 0.25-inch inner diameter and a 0.53-inch outer diameter, it is built for medium-pressure hydraulic circuits found in mobile equipment, industrial machinery, and fluid power systems. The black synthetic rubber construction provides flexibility and resistance to hydraulic fluids across a wide operating temperature range. A 2-inch bend radius allows routing in tight spaces without kinking. Hydraulic technicians and fluid power mechanics typically specify this hose for pressure lines requiring reliable performance under continuous dynamic loads.

This hose is suited for hydraulic pressure and return lines in both mobile and stationary equipment applications. The compact 0.25-inch ID makes it appropriate for pilot lines, control circuits, and low-flow pressure circuits where space and routing flexibility are priorities. It is sold in individual lengths and is compatible with standard 4-series hydraulic fittings. Technicians working on forklifts, skid steers, agricultural equipment, or industrial hydraulic power units will find this hose a straightforward replacement option for equivalent-specification lines.

Key Features

• 3,000 psi working pressure rating for medium-pressure hydraulic service
• 0.25-inch ID and 0.53-inch OD for compact routing in tight plumbing runs
• 2-inch minimum bend radius reduces kinking risk during installation
• Synthetic rubber construction compatible with common hydraulic fluids
• Rated to 212 degrees F maximum operating temperature
• Black exterior finish for standard hydraulic hose identification

Compatibility

Designed as an OEM-style replacement for medium-pressure hydraulic hose assemblies requiring a 0.25-inch ID, 3,000 psi rated synthetic rubber hose. Compatible with standard 4-series hydraulic hose end fittings.

Installation Notes

Hydraulic hose replacement should be performed by a qualified hydraulic technician or fluid power mechanic. Always depressurize the system and relieve all stored hydraulic pressure before disconnecting any hose. Verify that fittings are rated to at least the hose working pressure before assembly. Inspect hose routing to ensure the 2-inch minimum bend radius is maintained and the hose is secured away from heat sources, sharp edges, and moving components.
