Maintenance Notes & Preventative Measures:

Before Use

Select Correct Size - Always verify the correct inside diameter and cross-section using the size chart before installation.

Inspect O-Ring - Check for any visible defects, cuts, or deformation before use.

Clean Surfaces - Ensure mating surfaces are clean, smooth, and free of debris or old seal material.

During Installation

Lubricate Lightly - Apply appropriate lubricant (silicone grease, oil, or assembly fluid) to prevent rolling or pinching during installation.

Avoid Sharp Edges - Use care when installing over threads or sharp edges to prevent cutting.

Do Not Over-Stretch - Stretch only enough to install; excessive stretching can damage the ring.

Seat Properly - Ensure O-ring sits evenly in groove without twisting.

After Installation

Check Position - Verify O-ring remains properly seated after assembly.

Test System - Pressure test or operate system to confirm proper seal.

Storage Guidelines:

Keep Organised - Always return O-rings to correct compartment after use.

Close Securely - Ensure case lid is fully latched when not in use.

Avoid Sunlight - Store in cool, dark places away from direct UV exposure.

Moderate Temperature - Avoid extreme heat or cold that can degrade rubber.

Chemical Separation - Keep away from solvents, oils, and chemicals when stored.

Preventative Maintenance Tips:

Size Chart Reference - Keep the size chart accessible for quick identification.

Inventory Check - Periodically count stock and restock frequently used sizes.

Material Compatibility - For critical applications, verify O-ring material compatibility with fluids being sealed.

Spare Essentials - Consider purchasing additional kits for frequently used sizes.

Common Applications Reference:

Oil Drain Plugs, 18-20mm ID × 1.78mm

Fuel Injectors, 7-10mm ID × 1.78mm

When to Replace O-Rings:

Visible cracks, cuts, or nicks

Flattening or permanent deformation

Hardening or loss of elasticity

Swelling or chemical damage

Leakage despite proper installation

Safety Guidelines:

Pressure Systems - Depressurize systems before removing or installing O-rings

Fluid Compatibility - Ensure O-ring material suits the fluid type (oil, fuel, water, etc.)

Temperature Limits - Verify operating temperature stays within material limits

Eye Protection - Wear safety glasses when working with pressurized systems

Proper Disposal - Discard damaged O-rings appropriately
