Alemite 6703-B Grease Gun Hose 18 Inch With Coupler

The Alemite 6703-B is an 18-inch grease gun hose assembly with a 1/8 in NPTF(m) hose end and a 308730 coupler, rated for 4,800 psi (330 bar). The hose segment used is Alemite part 317850-1F, and the overall assembly measures 18 inches long (about 45 cm). For use with hand-operated grease guns only, this design provides extended reach to reach stubborn grease fittings without repositioning the gun. The 1/8 in NPTF(m) hose end threads onto standard grease gun fittings, while the 308730 coupler engages compatible fittings to maintain a secure, leak-free connection at high pressure. This assembly is suited to automotive, industrial, and equipment lubrication tasks where a flexible hose helps access recessed or awkward grease points while delivering consistent grease flow up to 4,800 psi. As a standard replacement part within Alemite's grease gun accessory line, it integrates with existing Alemite hoses and couplers, ensuring reliable performance and compatibility across compatible hand-operated systems.
