Frequently Asked Questions

What is the difference between a gasket and a seal?

A gasket is typically used to fill the space between two flat, stationary surfaces (like a head gasket or compressor port gasket) to prevent leakage. A seal is generally used to prevent leakage between parts that move relative to each other (like a valve stem seal or a rotating shaft seal), or for weatherproofing gaps (like door seals).

How do I know when my car door seals need replacing?

Signs that your weather stripping needs replacement include excessive wind noise while driving, water leaks into the cabin during rain, visible cracking or hardening of the rubber, or doors that rattle or close improperly. Replacement strips (like the D-Shape or L-Shape options) are generally easy to install yourself.

Are universal A/C O-ring kits reliable for professional repairs?

Universal A/C O-ring and gasket kits (like the 265 Pcs kit) are excellent for providing a wide range of sizes for various applications. While they are reliable, for critical, high-pressure repairs on specific OEM systems, some mechanics prefer OEM or highly specialized seals to ensure perfect fitment and material compatibility.
