High Quality Metal Cased Oil Seal Supplier with Ample Stock

Metal-cased oil seal are widely used in pumps, gearboxes, motors, engines,
hydraulic systems, and heavy machinery. Their dual function—keeping lubricants
inside while blocking dust and contaminants—makes them essential for reliable
equipment performance. However, one aspect that is often underestimated is
storage. If seals are stored improperly, they may harden, crack, or deform
before they are ever installed.

Material Characteristics

Several common rubber compounds are used for metal-cased oil seal:

· NBR (Nitrile Rubber): Good resistance to oils but vulnerable to ozone and
high temperatures. It should be kept away from heat and direct sunlight.

· FKM (Fluoroelastomer): Excellent resistance to heat and chemicals but not
ideal in prolonged humidity.

· ACM (Acrylic Rubber): Performs well under oil and heat exposure, though
sensitive to UV light.

· EPDM (Ethylene Propylene Rubber): Strong resistance to aging and steam, but
incompatible with mineral oils.

Because each compound reacts differently to its environment, storage guidelines
should be adapted to the material.

Storage Guidelines

In general, oil seals should be stored in a cool, dry, and stable environment.
A temperature range of 10°C to 25°C and a relative humidity of 40% to 70% is
considered suitable. Packaging should remain intact until use. If cartons are
opened, seals should be resealed to avoid oxidation and ozone exposure.

Another detail is to avoid long-term pressure on the sealing lips. Stacked
seals that bear weight for months may deform, which directly compromises their
sealing ability once installed.

Why It Matters for Distributors

For distributors and wholesalers, improper storage means more than product
degradation—it means financial loss and reputational risk. Clients in
industries such as automotive, trucks, heavy equipment, metallurgy, wind
energy, and chemicals expect seals that are reliable right out of the box. If
seals show signs of premature aging, buyers may look elsewhere for supply.

Therefore, professional storage practices can be a selling point for
distributors. A warehouse that demonstrates proper handling and inventory
management can strengthen trust with clients.
