Parker 6125-24 Hydraulic Wing Nut Coupler 1-1/2 in Brass Fnpt

Product Description

The PARKER 6125-24 is a straight-body wing nut coupler designed for hydraulic hose connections in high-demand fluid power applications. Part of the Parker 6100 Series, this coupler features a 1-1/2 inch female NPT (FNPT) threaded connection and a brass body construction rated for working pressures up to 2,000 psi. The wing nut design allows for fast, tool-optional hand-tightened connections, reducing downtime during field service. Licensed hydraulic technicians and fluid power mechanics install this fitting in systems where a secure, repeatable hose-to-port connection is required across a wide operating temperature range.

The 6125-24 is suited for use in demanding mobile and stationary hydraulic systems. Documented applications include dump trailers, engine test stands, oil field equipment, and submersible pump installations. The straight configuration and 1-1/2 inch coupler size make it a practical choice for high-flow hydraulic circuits where threaded brass fittings are specified. It is appropriate for both residential-scale and commercial-scale fluid power setups requiring reliable, repeated connect and disconnect cycles.

Key Features

• Brass body construction for corrosion resistance in hydraulic fluid environments
• 1-1/2 inch FNPT threaded connection for standard NPT port compatibility
• Wing nut design enables hand-tightened installation without special tooling
• Rated for working pressures up to 2,000 psi
• Operating temperature range from -40 degrees F to 250 degrees F
• Straight body profile for direct in-line hose-to-port connections

Compatibility

Designed for use with dump trailers, engine test stands, oil field equipment, and submersible pumps requiring 1-1/2 inch FNPT hydraulic hose connections. Part of the Parker 6100 Series hydraulic coupler line.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power mechanic. Depressurize and isolate the hydraulic circuit completely before disconnecting or installing any fittings. Apply thread sealant appropriate for hydraulic service to FNPT threads and hand-tighten the wing nut before applying final torque with a wrench, following standard hydraulic fitting practices. Inspect the connection for leaks before returning the system to full operating pressure.
