💡 What is an O-ring seal and where is it used?

O-ring seals provide a handy leak-prevention option in many systems. - O-rings seal gaps between mating parts to prevent leaks in hydraulic and pneumatic systems.
- They resist oils, fuels, and hydraulic fluids and perform across a wide temperature range.
- Use AS568-017 compliant sizes to ensure proper fit and sealing performance.
- NBR 70A offers good chemical resistance and long-lasting durability.
