O-Ring Specific Tolerance Table
This sheet covers dimensional tolerance specifications for both custom molded and standard O‑rings, including inner diameter and cross‑section.
We set tolerance grades in accordance with ISO 3302‑1. For O‑rings with an inner diameter exceeding 670 mm, the tolerance is 0.64% of the inner diameter. Multiple precision classes are available to suit general industrial, hydraulic and high‑demand sealing applications.
All tolerance documentation can be supplied for your incoming inspection, supplier audits and drawing reference. Tighter tolerances can be negotiated for special high‑precision projects
.
We can provide complete physical test reports according to your material requirements, including hardness, tensile strength, elongation, compression set, temperature range and chemical resistance.
We are able to supply COA, COC and compliance documents for REACH, RoHS, FDA and UL. Batch traceability is guaranteed for custom molded sealing parts
