Parker 6105-20 Hydraulic Hose Fitting 1-1/4 in Brass Nptf

Product Description

The PARKER 6105-20 is a female pipe rigid nipple fitting designed for hydraulic hose assemblies operating under high-pressure fluid power conditions. Built from solid brass with NPTF (National Pipe Taper Fuel) threads, this straight fitting provides a leak-resistant, dryseal connection in demanding hydraulic systems. It carries a maximum working pressure of 2,500 psi and handles temperatures from -40 degrees F to 250 degrees F. The 1-1/4 inch hose size and 1-1/4 inch thread size make it suitable for larger-bore hydraulic lines where secure, rigid termination is required. Hydraulic system technicians and field mechanics are the primary installers of this fitting.

This fitting is suited for mobile and stationary hydraulic applications that demand reliable pipe-thread connections in high-vibration or high-cycle environments. Typical use cases include dump trailer hydraulic circuits, engine test stands, oil field equipment, and submersible pump systems. The rigid nipple design prevents hose rotation at the connection point, which is especially useful in fixed plumbing runs where torque and movement must be controlled. The fitting is part of the Parker 6100 Series, which covers brass hydraulic hose end fittings for industrial and mobile hydraulic use.

Key Features

• Brass construction provides corrosion resistance in hydraulic fluid and mild chemical environments
• NPTF dryseal thread form creates a pressure-tight connection without relying solely on sealant
• Straight body shape simplifies inline hose-to-pipe connections in tight plumbing runs
• 2,500 psi maximum working pressure rated for demanding hydraulic service
• Wide temperature range from -40 degrees F to 250 degrees F covers most mobile and industrial operating conditions
• Rigid nipple design prevents hose rotation and maintains connection integrity under vibration

Compatibility

Designed for use with dump trailers, engine test stands, oil field equipment, and submersible pumps requiring a 1-1/4 inch NPTF female pipe rigid nipple connection. Part of the Parker 6100 Series of brass hydraulic hose fittings.

Installation Notes

Installation should be performed by a qualified hydraulic technician. Depressurize and isolate the hydraulic circuit fully before removing or installing any fittings. NPTF threads are designed as dryseal connections, but thread sealant tape may be applied per site procedures and applicable fluid power standards. Inspect threads for damage before installation and do not overtighten, as brass fittings are susceptible to thread distortion under excessive torque.
