Aluminum camlock couplings can be used with caution with specific grease lubricants, but must strictly follow the adaptation principles, otherwise it may cause seal failure or corrosion. The specific points are as follows:

1. Parts and types of grease allowed for lubrication
Cam shaft: A very small amount of lithium based grease (butter) can be applied to the pivot point of the cam handle to prevent jamming caused by dust accumulation. Operation requirements: Dip a cotton swab in rice sized fat and apply it to the gap of the shaft, and wipe off any excess fat.
Male connector slot (non sealing surface): The sliding surface of the metal buckle can be thinly coated with PTFE paste (commonly known as PTFE paste) to reduce wear.

2. Parts that are strictly prohibited from lubrication
Sealing gasket and pressing surface: Rubber gaskets (such as nitrile rubber, fluororubber) or aluminum sealing surfaces must not be coated with grease, as grease can cause: ▶  Rubber swells and deforms, losing its sealing properties;   ▶  Oil and dust adsorption accelerates gasket wear;   ▶  The sealing surface slips and the cam locking torque decreases, causing leakage.
Internal wall of female joint: Oil and grease in contact with transmission media (such as oil and chemicals) may contaminate the material.

3. Hard rules for selecting oils and fats
Compatible with aluminum materials: Choose lubricating grease that is acid free, alkaline free, and free of free chloride ions (such as food grade white grease) to avoid corrosion of aluminum alloys.   ▶  Prohibit ordinary industrial butter: Sulfur/chlorine additives can corrode aluminum surfaces.
Medium resistance: If the joint is used in an oil environment, hydrocarbon solvent resistant grease (such as perfluoropolyether paste) must be selected to prevent the grease from being dissolved by fuel.
Temperature adaptation: Synthetic alkyl grease is used for high temperature scenarios (>80 ℃), and silicone grease is used for low temperature environments (<-20 ℃).

4. Alternative lubrication solutions
Dry film lubrication optimization: use molybdenum disulfide spray or graphite powder to spray the cam shaft to form a dry lubrication film, which will not stain dust and pollute the sealing surface.
Self lubricating component upgrade: Oil containing sintered copper shaft sleeves can be replaced for frequently moving parts, maintenance free.

5. Operation taboos
Prohibited from spraying WD-40 solvent oil: short-term rust removal is effective, but solvent penetration into rubber gaskets can cause them to crack and residual oil film can damage the seal.
Do not mix different oils: Mixing lithium based grease with silicone grease will cause clumping and failure.
