Parker PQ-00099 Hydraulic Hose Coupler 2700 Psi 3/4-14

Product Description

The PARKER PQ-00099 is a steel hydraulic hose coupler designed for use in hydraulic fluid power systems requiring reliable, leak-resistant connections. It accommodates a 12 mm hose size with a 3/4-14 thread and carries a pressure rating of 2,700 psi, making it suitable for moderate- to high-pressure hydraulic lines. The coupler is constructed from steel for durability under cyclic pressure loads. Hydraulic technicians and fluid power mechanics install this type of fitting during hose assembly, repair, or system reconfiguration on industrial and mobile hydraulic equipment.

This coupler is appropriate for use in hydraulic systems found in industrial machinery, mobile equipment, and fluid power circuits where a 3/4-14 threaded connection is required. It is suited for both new hose assemblies and replacement of worn or damaged couplers in existing hydraulic lines. The 12 mm hose diameter accommodates common mid-range hydraulic hose used in a variety of pressure-line applications.

Key Features

• 2,700 psi pressure rating supports moderate- to high-pressure hydraulic service
• 12 mm hose size with 3/4-14 thread for positive mechanical engagement
• Steel construction resists deformation under cyclic hydraulic loads
• Compact coupler form factor for use in tight hose routing layouts
• Single-piece packaging suitable for individual repair or replacement jobs

Compatibility

Designed as an OEM-style replacement coupler for hydraulic hose assemblies requiring a 12 mm hose size and a 3/4-14 threaded connection rated to 2,700 psi.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power mechanic. Depressurize and fully isolate the hydraulic circuit before disconnecting any hose or fitting. Use appropriate hose assembly tooling and inspect mating threads for damage before installation. Follow applicable hydraulic system standards and equipment manufacturer guidelines for torque and assembly procedures.
