O Rings - 3.53mm
About O Rings
These versatile seals are crucial in numerous business applications, functioning effectively by fitting into grooves and compressing between two or more parts to create a reliable seal. They are particularly useful in dynamic environments, including gas handling systems, as well as in static conditions such as pipelines or tanks. An o ring seal is widely used in these applications due to its ability to provide dependable sealing performance, while o ring seals are trusted across many industrial sectors.
At Henderson Bearings, common materials for O Rings, o rings, and o-rings include Nitrile (Buna-N), Viton® (FPM, FKM), Neoprene® (CR), EPDM, and Silicone (VMQ). These materials are often used alongside rubber gaskets and custom sealing components, each offering unique properties that cater to varying operational demands, temperature ranges, and environmental factors. Our rubber sealing products include standard o ring options, custom sealing solutions, and specialist rubber components designed for demanding environments.
O Ring, o-ring, and o rings products come in diverse sizes and material makeups to meet specific industry needs. Many are held in stock for fast supply, with options covering chemical compatibility, resilience, and overall durability, suitable for both standard and custom sealing requirements. Our stock includes small o rings, square o rings, and square section o rings for applications requiring specific sealing profiles and performance characteristics.

What are O Rings and why are they important in various industries?
O Rings are circular sealing elements designed to prevent leaks and maintain system integrity across multiple industries. They fit snugly into machined grooves to form tight seals, crucial in both dynamic movements and static conditions. For more specialised sealing applications, such as in split housings or around rotating shafts, alternatives like Rotary Shaft Seals or Seal Packs for Split Plummer Blocks may be more suitable.
How do I select the right O Ring for my application?
Choosing the right O Ring requires considering the specific conditions it will be exposed to, including pressure, temperature, and chemical environment. The material of the O Ring—such as Nitrile, Viton®, Neoprene®, EPDM, or Silicone—should be selected based on these factors for optimal performance and durability. If you're building a kit for multiple applications or repairs, our O Ring Selection Kits offer a convenient solution with assorted sizes and materials.
What are the common uses of O Rings?
O Rings are versatile and used in many industries, including automotive, aerospace, and manufacturing. They are particularly valuable in systems where precise sealing is necessary, such as in fluid transfer equipment, hydraulic and pneumatic systems, and various types of pumps and valves. For sealing applications involving fork components or shock absorbers, Hydraulic Damper Fork Seals may be more appropriate.
Can O Rings fail, and how can I tell if they need replacing?
O Rings can fail due to wear and tear, improper sizing or material choice, or degradation from chemicals or temperatures. Signs of failure include leakage, visible cracking or brittleness, and loss of flexibility or shape. Regular inspection and maintenance can help identify when replacements are needed. In environments prone to contamination or high-speed rotation, you may also want to consider using Nilos Sealing Rings or Sealing Washers as part of your overall sealing solution.
