dust seal vs oil seal
In addition to protecting against external contaminants, dust wiper seals also help retain lubrication within the system. By preventing dust and dirt from entering the system, these seals help reduce friction between moving parts, which can prolong the life of the equipment and reduce maintenance costs. Proper lubrication is essential for the smooth operation of hydraulic cylinders, pneumatic systems, and other machinery, and dust wiper seals play a vital role in ensuring that lubricants stay where they are needed most.

While weight and packability are critical, never compromise on space. When choosing a tent, consider how many people will be using it and their comfort levels. A two-person tent should allow enough room for sleeping comfortably and storing gear. Additionally, think about the tent design; vertical walls offer more internal space than sloped ones. If you plan to spend extended periods in the tent, a little extra space can make a significant difference in comfort.
