Melkib MB-0279 90° M12×1 zinc-plated angle grease fitting

Melkib MB-0279 90° M12×1 angle grease fitting for point lubrication

Melkib MB-0279 is an angle grease fitting with an M12×1 thread and a connection head positioned at 90°. It is designed to supply grease to bearings, pins, joints, guides and other machine components equipped with a threaded lubrication point.

The angled construction makes it easier to connect a grease gun where a machine housing, guard or adjacent component restricts direct access along the axis of the threaded port.

Applications of the Melkib MB-0279 grease fitting

The fitting can be used as a permanent lubrication point in machines, equipment, vehicles and mechanical assemblies equipped with an M12×1 threaded port.

Typical applications include point lubrication of:

• bearings,
• pins,
• joints,
• guides,
• other moving components requiring periodic greasing.

Key features of the MB-0279 grease fitting

The component is made of free-cutting steel and has a zinc-plated surface. Its 90° configuration changes the grease gun connection direction and allows the lubrication point to be accessed from the side.

The fitting is compatible with standard jaw-type couplers used with manual and pneumatic grease guns.

When to choose the M12×1 90° version

Choose the MB-0279 when the equipment documentation or removed fitting specifies an M12×1 thread and side access to the lubrication point is more convenient than direct axial access.

Before purchase, verify both the M12 nominal thread diameter and the 1 mm thread pitch. The M12 designation alone does not confirm full compatibility.

Installation guidance

Before installation, clean the threaded port of old grease, dust and other contamination. Start threading the fitting by hand and keep it aligned with the thread axis.

If significant resistance occurs, stop the installation and check the thread diameter and pitch again. Do not compensate for an incorrect fit by applying excessive force.

Storage

Store in a clean and dry place. Protect the fitting from moisture, dust, metal particles and contamination of the grease passage. Clean the connection head before installation and before each lubrication operation.

FAQ

Does the MB-0279 fit every M12 thread?

No. Both the nominal diameter and the thread pitch must match. The MB-0279 is intended for an M12×1 threaded port.

When should a 90° angle grease fitting be used?

It is used where a housing, guard or adjacent component restricts access to a straight grease fitting. The 90° construction allows the grease gun to be connected from the side.

Can the MB-0279 be used with a pneumatic grease gun?

Yes. It is compatible with manual and pneumatic grease guns equipped with a suitable jaw-type coupler.

Is the grease fitting made of stainless steel?

No. It is made of free-cutting steel with a zinc-plated surface.
