Lincoln Industrial Lubrication 5191 Fitting, (Card of 10)

Lincoln Industrial Lubrication 5191 fittings (card of 10). These metal lubrication fittings are designed for use across automotive, agricultural, marine, truck, construction equipment and machine manufacturing industries. The fittings feature a true spherical contour on the fitting head that provides a natural ball-and-socket joint with commercial hydraulic couplers for wide-angularity contact and a tight metal-to-metal seal. The internal spring is tempered with music wire and coiled to prevent compression that could restrict flow of heavy lubricants or be forced out under normal pressures. A specially formed lip at the fitting base locks the spring and ball securely in place; the fittings can be wiped clean without forcing foreign material into the fitting or bearing. Ideal as grease-gun accessories and replacement fittings for maintenance operations; card of 10 pieces; NPT thread; coupling connector type; model 5191.
