Nu-Calgon Penetrate HD Lubricant - 61105P

Restore freer movement on stuck, rusty, or tightly fitted parts with this universal/spec-match Nu-Calgon Penetrate HD Lubricant - 61105P. This heavy-duty penetrating lubricant helps loosen seized hardware while leaving behind light protection against rust and moisture.

61105P is Nu-Calgon Penetrate HD, a universal/spec-match service lubricant used when stuck fasteners, corroded hardware, and tight metal assemblies need penetrating action rather than a heavy grease. It is commonly used in HVAC, appliance, and general maintenance work for freeing seized parts before disassembly.

Compatibility: General appliance, HVAC, refrigeration, and shop maintenance applications on compatible metal parts that need penetrating lubricant.

Please confirm the lubricant type, application point, and equipment-service requirement before ordering.

Is it time to replace?

• Common Symptoms: Frozen screws or bolts, rusty hardware, stiff pivots, or moving parts that are difficult to free during service.
• Visible/Sensory Cues: Light corrosion, binding at a fastener or pivot, squeaks after moisture exposure, or hardware that needs repeated effort to loosen.

Pro Tip: Spray the area and allow a short soak time before forcing the fastener so the penetrant has time to work into the joint.
