It connects hydraulic hose lines in high-pressure fluid power systems, providing a secure, leak-resistant junction between hose and fitting. The coupler is sized for 6 mm hose with a 3\/8-18 thread and is built from stainless steel for corrosion resistance in demanding environments. Hydraulic technicians and fluid power mechanics install this coupler in mobile equipment, industrial machinery, and other high-pressure hydraulic circuits where reliable connections are critical.\u003c\/p\u003e\u003cp\u003eThis coupler is suited for residential and commercial hydraulic applications where stainless steel construction is required to resist corrosion from moisture, chemicals, or harsh operating conditions. Typical installation scenarios include industrial hydraulic systems, heavy equipment hose assemblies, and fluid power lines that require a 6 mm hose connection with 3\/8-18 thread compatibility. The 5,500 psi pressure rating supports demanding high-pressure circuits.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5,500 psi pressure rating for high-pressure hydraulic service\u003c\/li\u003e\n\u003cli\u003eStainless steel construction resists corrosion and chemical exposure\u003c\/li\u003e\n\u003cli\u003e6 mm hose size with 3\/8-18 thread for precise fitment\u003c\/li\u003e\n\u003cli\u003eCompact design suitable for tight installation spaces\u003c\/li\u003e\n\u003cli\u003eSold in a package quantity of 2 couplers per order\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or service coupler for hydraulic hose assemblies requiring a 6 mm, 3\/8-18 threaded stainless steel coupler rated to 5,500 psi.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified hydraulic technician or fluid power mechanic. Always depressurize and bleed down the hydraulic system before disconnecting or installing any coupler. Verify thread type and hose size before installation to prevent mismatched connections.
