Why is Lubrication Essential for Slide Out Gaskets?
Lubrication is essential for slide out gaskets because it ensures proper sealing, prevents wear and tear, and prolongs the life of the gaskets. Proper lubrication reduces friction, which can lead to damage over time.
According to the Recreational Vehicle Industry Association (RVIA), maintaining slide outs is crucial for functionality and longevity, and lubrication plays a vital role in this maintenance.
The underlying reasons for the necessity of lubrication include minimizing friction and wear on the gaskets. Friction occurs when surfaces rub against each other. Without lubrication, this friction can cause the rubber or vinyl gaskets to crack or degrade. Additionally, dirt and debris can accumulate on unlubricated surfaces, exacerbating wear.
Lubrication refers to applying a substance, typically oil or grease, to reduce friction between surfaces. In the context of slide out gaskets, the lubricant fills microscopic spaces, creating a smoother interface for movement. Natural rubber and vinyl gaskets are subjected to environmental factors like temperature changes, UV exposure, and moisture, which can lead to hardening or brittleness if not properly maintained.
Specific actions that contribute to the deterioration of slide out gaskets include exposure to extreme weather conditions and the absence of regular maintenance. For example, not lubricating the gaskets before the winter season can lead to stiffness. Additionally, when slide outs are extended or retracted without proper lubrication, the gaskets may drag across surfaces, causing wear. Applying the recommended lubricant regularly, especially in areas with harsh weather, significantly improves the lifespan and performance of slide out gaskets.
