The PARKER KP61667 is a 2-piece reusable hose fitting designed for low-pressure and medium-pressure fluid line assemblies. It accepts hose with a 5/16 inch inner diameter and a 3/8 inch outer diameter, and threads onto mating connections via a 5/8-18 thread. The reusable design allows the fitting to be disassembled and reinstalled on a replacement hose without the need for specialized crimping equipment, making it a practical choice for field repairs and maintenance work performed by plumbers, hydraulic technicians, and mechanical contractors.
This fitting is suited for use in hydraulic, pneumatic, and fluid transfer hose assemblies where a 5/16 inch ID hose is specified. The 5/8-18 thread size is a standard straight or unified thread configuration commonly found on fittings used in light hydraulic and industrial fluid systems. It is typically installed during hose assembly fabrication or as a replacement fitting during field service on existing hose runs.
Designed as an OEM-style replacement or service fitting for hose assemblies using 5/16 inch ID hose with a 3/8 inch OD and a 5/8-18 threaded end connection.
Installation is typically performed by a plumber, hydraulic technician, or mechanical contractor familiar with hose fitting assembly procedures. Depressurize and drain the hose assembly completely before disassembling or replacing any fitting. Follow the fitting manufacturer's assembly instructions for proper thread engagement and hose insertion depth. Do not overtighten — consult applicable industry standards for the fitting type and application.
