Metal oil seals are available in a variety of designs and configurations to suit different applications
. Some seals are designed to withstand higher temperatures and pressures, while others are specifically engineered for use in specific types of machinery or equipment. This versatility makes metal oil seals a versatile and reliable solution for a wide range of sealing requirements.

Oil seals are generally constructed from materials that can withstand the specific chemical properties of the lubricant they are sealing. Common materials include rubber, silicone, and various elastomers. The design of an oil seal often incorporates a lip that rolls against a shaft or surface, creating a dynamic seal that can accommodate movement while maintaining its sealing capabilities.

Some steel and iron fence manufacturers will cut corners here. Especially in the rail-to-picket connection (the rail is the horizontal piece and the picket is the upright one). The worst ones we’ve seen is companies using rivets or screws to connect the pickets to the rails. While this works fine on a lighter aluminum fence, it does not work as well on an iron or steel fence. Not only does a weaker connection result in a ‘loose’ feeling panel, but the rivets can allow movement which can scratch down to bare metal and create rust spots.
