Parker KP46915 Female Npt Swivel Fitting 4mm 1/4-18 Nptf

Product Description

The PARKER KP46915 is a female NPT swivel fitting designed for hydraulic hose assemblies requiring a 1/4-18 NPTF threaded connection. Constructed from steel, this fitting accommodates a 4 mm hose size and delivers a reliable, leak-resistant connection in hydraulic systems. The swivel design allows the fitting to rotate during installation, reducing hose twisting and making it easier to achieve proper alignment without putting stress on the hose or surrounding components. It is installed by hydraulic system technicians and mechanics working on mobile, industrial, or fluid power equipment.

This fitting is suited for hydraulic hose assemblies in both mobile and stationary fluid power applications. The NPTF thread form provides a pressure-tight seal on metal-to-metal contact, making it appropriate for systems where thread sealant compatibility and leak-free performance are critical. The 1/4-18 thread size is common in lighter-duty hydraulic lines, control circuits, and auxiliary fluid systems. Sold in a package quantity of four, this fitting is practical for service shops and technicians completing multiple hose assemblies in a single job.

Key Features

• Female NPT swivel design allows rotation during installation to prevent hose twist
• NPTF thread form provides metal-to-metal sealing without reliance on thread sealant alone
• 1/4-18 thread size fits standard hydraulic hose end connections in this class
• Steel construction for durability in hydraulic pressure environments
• Sold as a package of 4 fittings for multi-hose service work

Compatibility

Designed as an OEM-style replacement or service fitting for hydraulic hose assemblies using 4 mm hose with a 1/4-18 NPTF female swivel thread end.

Installation Notes

Installation should be performed by a qualified hydraulic technician or mechanic. Depressurize and isolate the hydraulic circuit completely before removing or installing any fittings. Inspect threads and sealing surfaces for damage before assembly. Do not overtighten NPTF fittings; follow the fitting manufacturer's recommended turns-past-finger-tight procedure and verify system pressure integrity after installation.
