Parker BD-4000-3P-1 Hydraulic Hose Coupler 2500 Psi

Product Description

The PARKER BD-4000-3P-1 is a threaded hydraulic hose coupler designed for use in fluid power systems requiring reliable pressure containment and secure hose termination. It accepts hose with a 0.375 inch inside diameter and carries a maximum working pressure rating of 2,500 psi. The threaded connection type ensures a positive, leak-resistant joint suited to demanding hydraulic circuits. This coupler is installed by hydraulic technicians and maintenance mechanics working on mobile equipment, industrial machinery, and fluid power assemblies.

This coupler is intended for hydraulic systems that use 3/8 inch hose with a 0.375 inch inside diameter. Typical applications include industrial hydraulic power units, mobile equipment hydraulic lines, and similar fluid power circuits where a threaded coupler fitting is specified. Its compact form factor makes it suitable for tight routing environments common in both mobile and stationary hydraulic installations.

Key Features

• 0.375 inch hose inside diameter accommodates standard 3/8 inch hydraulic hose
• 2,500 psi maximum working pressure rating for demanding hydraulic circuits
• Threaded connection type provides a secure, leak-resistant joint
• Compact and lightweight at 0.01 pounds for use in space-constrained assemblies

Compatibility

Designed as an OEM-style replacement or service fitting for hydraulic systems utilizing 3/8 inch inside diameter hose with threaded coupler connections rated to 2,500 psi.

Installation Notes

Installation should be performed by a qualified hydraulic technician or mechanic. Before servicing any hydraulic fitting, fully depressurize the hydraulic circuit and relieve all stored energy in accumulators. Inspect mating threads and hose end condition before assembly. Follow applicable fluid power standards and equipment manufacturer torque guidance for threaded hydraulic fittings.
