Frequently Asked Questions

Select based on size (inner diameter & cross-section), material compatibility with system fluids (refrigerants, oils, water, etc.), and pressure/temperature rating. Using the wrong seal can lead to premature failure or chemical degradation.

Yes, properly sized and installed O-rings and gaskets form a tight seal between mating surfaces, helping to prevent refrigerant, oil, or fluid leaks in HVAC and plumbing systems.

Materials like Buna-N (NBR), EPDM, FKM (Viton), and others vary in chemical resistance and temperature tolerance. Pick a material that’s compatible with your refrigerant and lubricant to ensure long life.

Generally no, once compressed and used, O-rings and gaskets lose elasticity and sealing effectiveness. It’s best practice to replace them during service or component swaps.

Part costs range from a few dollars for small O-rings to larger gasket sets, but professional service labor can significantly increase total cost depending on accessibility and system type.

Yes, cuts, twists, or pinching during installation can compromise sealing performance. Proper lubrication and careful seating in the groove are critical for reliable operation.

Some kits bundle common sizes for specific systems, making service easier. Always confirm the kit contents match the sizes and types required for your exact application.
