FAQ

Q1: What is the significance of “70 ShA” in this O-Ring specification?
A1: “70 ShA” refers to the hardness of the rubber compound on the Shore A scale. A hardness of 70 Shore A gives the O-Ring a dependable mix of flexibility and resilience, suited to industrial sealing tasks where the seal must adapt and still resist deformation.

Q2: Can these NBR O-Rings be used in high-pressure hydraulic systems?
A2: Yes — they are suitable for many hydraulic sealing applications, particularly static or low-motion seals. For high-pressure dynamic conditions, ensure correct groove design, proper compression and compatible fluid/media. The NBR material offers strong oil resistance, enhancing longevity.

Q3: How do I know if the 10x3 mm dimension fits my application?
A3: Verify the groove or housing specification: the inner diameter 10 mm and cross-section thickness 3 mm must match or fit within your available groove geometry. This ensures proper compression and sealing performance. If the groove differs significantly, consider alternate sizing.

Q4: Why choose a set of 100 instead of individual O-Rings?
A4: For industrial buyers and B2B operations, a bulk pack of 100 allows simplified purchasing, reduces unit cost, ensures availability for maintenance or production cycles, and prevents downtime caused by lack of spare seals.
