Critical Technical Specifications to Understand

When sourcing AS 568 O-rings in international B2B settings, clarity on key technical properties is essential for aligning supplier deliverables with application demands, regulatory standards, and long-term operational efficiency. Here are the most critical specifications and why they matter:

1. Material Grade and Compound
The base material (such as Nitrile, Viton/FKM, Silicone, EPDM, or FFKM) directly influences the O-ring’s chemical compatibility, temperature resistance, durability, and certification suitability. For example, FKM is broadly chosen for its chemical and heat resistance, while EPDM excels in water and steam applications. Confirm the exact compound and its standards (e.g., FDA, WRAS, or specific ASTM/ISO grades) to avoid compatibility failures and regulatory non-compliance, which are especially relevant for medical, food, potable water, and chemical sectors.

2. Dimensional Tolerance
AS 568 O-rings are defined by very precise dimensional tolerances—covering inside diameter (ID), cross-sectional diameter (CS), and overall thickness. This precision ensures seamless interchangeability and reliable sealing performance across global supply chains. Dimensional accuracy is essential for preventing leaks and costly equipment downtime, especially when mating parts come from different suppliers or regions.

3. Hardness (Shore A)
Measured on the Shore A durometer scale (commonly 70A for general-purpose O-rings), hardness impacts flexibility, resistance to pressure, and sealing ability. Too hard, and the O-ring might not conform well to hardware surfaces; too soft, and it may extrude or fail under pressure. Identifying the correct hardness rating enables optimal performance in demanding hydraulic, pneumatic, or static sealing environments.

4. Temperature and Chemical Resistance Range
Each O-ring material operates within specific temperature limits and resists distinct sets of chemicals. For critical B2B deployments—such as in oil & gas, food processing, or outdoor energy systems—specifying the minimum and maximum continuous temperatures and the chemical exposure context ensures reliable, long-term performance. Always match these parameters to your exact operating environment.

5. Compliance and Certification Requirements
In many sectors, especially those exporting to the EU, Middle East, and parts of Africa, O-rings must meet certifications such as REACH, RoHS, FDA, or relevant local standards. Certification ensures products meet health, environmental, or market-entry requirements, minimizing legal risk and smoothing customs clearance.

6. Shelf Life and Storage Stability
Elastomeric properties degrade over time based on composition and storage. Understanding and specifying minimum shelf life ensures that inventory remains usable and compliant, especially important for buyers managing larger, regional distribution or slow-moving stocks.
