Frequently Asked Questions
Q: What material are these O-rings made from, and why does it matter?
A: These O-rings are made from Nitrile Rubber (NBR), which is one of the most widely used sealing materials in industrial and household applications. NBR provides excellent resistance to petroleum-based oils, fuels, hydraulic fluids, and water, making it suitable for a broad range of plumbing, automotive, and mechanical sealing tasks.
Q: How many sizes are included in the 225-piece O-ring kit?
A: The kit contains 225 pieces spanning multiple sizes — varying in both inner diameter and cross-section (cord) thickness. This ensures you have a compatible O-ring for most standard fittings and repair jobs without needing to order specific sizes individually.
Q: Can these nitrile O-rings be used in high-pressure applications?
A: Yes. These O-rings are engineered to maintain a secure, leak-free seal under high-pressure conditions, making them appropriate for use in hydraulic systems, pneumatic tools, air compressors, and pressurized plumbing connections.
Q: Are these O-rings suitable for both water and oil-based systems?
A: Absolutely. Nitrile rubber has strong resistance to both water and petroleum-based fluids, so these O-rings work reliably in water plumbing systems as well as oil and fuel line applications in automotive or machinery contexts.
