Rated to 6,700 psi maximum working pressure, this threaded coupler accepts a 4 mm (1\/4 inch) hose and features a 1\/4-18 NPTF thread connection for a pressure-tight seal without sealant tape. The Series ST design supports a maximum flow rate of 6.00 GPM. At 1.54 inches overall length, the compact body fits in tight plumbing configurations. This part is installed by hydraulic system technicians and industrial maintenance professionals working on mobile or stationary hydraulic circuits.\u003c\/p\u003e\n\u003cp\u003eThis coupler is suited for use in industrial, mobile equipment, and manufacturing hydraulic circuits where compact, high-pressure fittings are required. The NPTF threaded connection makes it appropriate for systems where a dry-seal thread is preferred over standard NPT. It is commonly used in hydraulic lines on machinery, presses, and fluid power equipment operating within its rated pressure range. Sold in a package quantity of two.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e6,700 psi maximum working pressure for demanding hydraulic applications\u003c\/li\u003e\n  \u003cli\u003eStainless steel construction for corrosion resistance in harsh or wet environments\u003c\/li\u003e\n  \u003cli\u003e1\/4-18 NPTF dry-seal thread eliminates the need for thread sealant tape in most installations\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch hose diameter compatibility with 1.54 inches overall length for compact fitment\u003c\/li\u003e\n  \u003cli\u003eMaximum flow rate of 6.00 GPM suitable for typical small-bore hydraulic circuits\u003c\/li\u003e\n  \u003cli\u003eParker Series ST design for consistent dimensional and performance standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service fitting for hydraulic hose assemblies requiring a 4 mm, 1\/4-18 NPTF threaded coupler rated to 6,700 psi.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified hydraulic technician. Depressurize and bleed the hydraulic system fully before disconnecting any fittings or hose assemblies. NPTF threads are designed as dry-seal connections; inspect thread condition before installation and confirm thread engagement meets system requirements.
