Grease Fitting Junction Blocks


Grease Fitting Junction Blocks	Magnetic Grease Fitting Junction Blocks	Inlet

Choose these blocks if you need to lubricate multiple points but need to control how each is greased. Unlike grease fitting manifolds, these blocks have multiple fittings, so you control what each point receives and when. Use the compression fittings on the outlets to connect tubing (not included) between the grease fittings and lubrication points.

Magnetic Grease Fitting Junction Blocks—Magnetic blocks stick to machines and other steel surfaces.

Zinc-Plated Steel—Zinc-plated steel blocks have mild corrosion resistance.

303 Stainless Steel—303 stainless steel blocks are more corrosion resistant than zinc-plated steel blocks and have good chemical resistance.

Grease Fitting Manifolds

Save time by sending grease from one fitting to multiple points. These manifolds come with everything you need to set up a remote lubrication system. They deliver the same amount of grease to each lubrication point, so you’ll sometimes see them used to grease an entire machine. All lubrication points connected to the manifold must use the same type of grease.

The tubing attaches to the compression fittings on the manifold’s outlets.

Includes—To connect the other end of the tubing to your lubrication point, use a compression fitting, an adapter, or both. Adapters come in a variety of shapes and sizes to reach tight or hard-to-reach areas.
