Parker PQ-00061 Hydraulic Hose Coupler 2500 Psi 8mm

Product Description

The PARKER PQ-00061 is a steel hydraulic hose coupler designed for threaded hydraulic line connections in industrial and mobile hydraulic systems. It carries a maximum working pressure of 2,500 psi and accepts an 8 mm hose with a 1/2-14 NPSF threaded connection. At 1.81 inches in overall length, this coupler fits into tight plumbing configurations without sacrificing flow capacity. The NS-series design supports a maximum flow rate of 12.00 GPM, making it well suited for moderate-duty hydraulic circuits. Licensed hydraulic technicians and industrial mechanics install this part as a standard line coupling component.

This coupler is intended for use in hydraulic assemblies requiring a 1/2-inch NPSF threaded interface and a compatible 8 mm hose diameter. It is a practical fit for both stationary industrial equipment and mobile machinery where consistent pressure integrity is required. The steel construction handles the mechanical and pressure demands common in hydraulic power units, cylinders, and manifold connections. Sold in packages of two units per package quantity, making it convenient for service kits or paired-port installations.

Key Features

• 2,500 psi maximum working pressure for reliable performance in standard hydraulic circuits
• 1/2-14 NPSF threaded connection ensures a secure, leak-resistant fit
• 8 mm hose size compatibility with a 0.5000-inch coupler bore
• Maximum flow rate of 12.00 GPM supports moderate-duty hydraulic applications
• Steel construction provides durability under mechanical stress and hydraulic pressure cycling
• Compact 1.81-inch overall length suits space-constrained hydraulic plumbing

Compatibility

Designed as an OEM-style replacement or service coupler for hydraulic systems requiring an 8 mm hose, 1/2-14 NPSF threaded coupler rated to 2,500 psi. Verify thread type, hose diameter, and pressure rating against your existing system specifications before installation.

Installation Notes

Installation should be performed by a qualified hydraulic technician or industrial mechanic familiar with hydraulic circuit safety procedures. Depressurize and lock out the hydraulic system fully before removing or installing any coupler. Use appropriate thread sealant compatible with hydraulic fluid and the NPSF thread form. Inspect hose and mating fittings for wear or damage prior to assembly and confirm all connections are torqued to system specifications.
