Parker KP61658 Reusable Hose Male Fitting 1/4 Npt

Product Description

The PARKER KP61658 is a two-piece reusable male hose fitting designed for hydraulic and fluid transfer hose assemblies. It threads onto the hose end with a 1/4 NPT male thread and accepts a 5/16-inch hose ID, providing a secure, field-reattachable connection without requiring crimping equipment. This fitting is suited for low- to medium-pressure fluid lines in HVAC, plumbing, and industrial service applications. It is typically installed by licensed plumbers, HVAC technicians, and fluid power technicians. The two-piece reusable design allows the fitting to be removed and reused when hose is replaced, reducing material waste on service calls. Each package contains four fittings.

This fitting is used wherever a 1/4 NPT male threaded connection is needed at a 5/16-inch ID hose termination. Common applications include hydraulic lines, coolant transfer hoses, and fluid control systems in residential and light commercial mechanical equipment. It is appropriate for shop-assembled hose lines and field repair situations where crimping tools are not available.

Compatibility

Designed as an OEM-style reusable hose fitting for fluid transfer hose assemblies requiring a 1/4 NPT male thread and a 5/16-inch hose ID connection.

Installation Notes

Installation is typically performed by a licensed plumber, HVAC technician, or fluid power technician. Shut off and depressurize the fluid system completely before removing or installing any hose fitting. Apply appropriate thread sealant to NPT threads per the system fluid compatibility requirements and follow applicable IPC or IFGC guidelines for the installation environment. Do not overtighten NPT threads, as tapered thread connections seal through thread engagement and excessive force can crack fittings or damage mating ports.
