Lincoln Filler Nipple 91108

The Lincoln Filler Nipple 91108 is a grease fitting designed for maintenance technicians and machinery operators. It connects to hand-operated and air-operated grease guns using a 1/8 inch MNPT thread. This component supports three-way loading for flexible lubrication access. It suits workshops and industrial sites needing reliable grease delivery points.

Thermals noise and power draw

As a passive mechanical fitting, the nipple generates no heat, produces no audible noise and draws no electrical power during normal use. Its operation depends entirely on the external grease gun supplying pressure. Thermal management, acoustic output and power consumption are therefore not applicable to this product.

Questions about this item

How do I install the 1/8 MNPT filler nipple on my grease gun, and what step is often missed?

Thread the 1/8 MNPT connection into the gun head until snug, then tighten with a wrench; the step often missed is applying thread sealant to prevent leaks under pressure.

What maintenance or replacement will the Lincoln 91108 filler nipple need over time?

Inspect the nipple regularly for thread wear or damage; replace it if the connection loosens, leaks grease, or the ball check fails to seat properly.
