Essential Technical Properties and Trade Terminology for 15 o ring

Critical Technical Properties of 15 O-Rings

When sourcing or specifying 15 O-rings for industrial or commercial applications, it is crucial for B2B buyers to clearly understand and communicate the core technical properties that determine performance, reliability, and compliance. The following attributes require special attention for cross-regional sourcing and risk mitigation:

• Material Composition (Grade & Type)
  The material—such as Nitrile (NBR), Fluorocarbon (FKM/Viton®), EPDM, or Silicone (VMQ)—directly influences the O-ring’s compatibility with chemicals, temperature ranges, and regulatory requirements. For example, NBR is suitable for oil and fuel systems, whereas EPDM excels in water and weather resistance. Selecting the correct grade also impacts compliance with industry standards (e.g., FDA, WRAS), which is vital for food, beverage, or medical sectors.

• Dimensions (ID, OD, and Cross-Section)
  A 15 O-ring typically refers to the inner diameter (ID) in millimeters, but cross-checking the outer diameter (OD) and cross-sectional thickness is essential for an effective seal. Precise tolerances ensure proper fit, prevent leakage, and minimize downtime due to installation errors. B2B buyers should always request detailed dimensional specifications and verification samples, especially for machinery with tight tolerances or varying international standards.

• Shore A Hardness
  This scale measures the rubber’s resistance to indentation (stiffness), typically ranging from 40 to 90 for O-rings. Hardness impacts the O-ring’s ability to compress, seal under pressure, and withstand mechanical stress. Lower hardness provides more flexibility but may wear faster under high pressure; higher hardness may offer greater durability but less conformability to irregular surfaces.

• Tensile Strength and Elongation at Break
  Tensile strength (measured in MPa) is the maximum stress the O-ring material can withstand before breaking, while elongation at break (percentage) reflects flexibility and deformation capacity. Higher values indicate better resistance to stretching, tearing, and mechanical damage—crucial for dynamic applications or environments with vibration and movement.

• Compression Set
  This indicates the O-ring’s ability to recover its original shape after being compressed for prolonged periods under heat or pressure. A low compression set means the material maintains sealing force and resists permanent deformation, which is vital for ensuring long-term reliability and minimizing maintenance interventions.

• Temperature and Chemical Resistance
  The operational temperature range and the O-ring’s chemical compatibility should align with the application environment. For instance, Silicone suits high and low temperatures, while FKM is preferable for strong acids or solvents. Mismatches can lead to rapid degradation, leakage, and compliance failures—pay close attention to international certifications and test data from suppliers.

Key Industry and Trade Terms Every B2B Buyer Should Know

Understanding core trading and industrial terms eliminates miscommunication with global suppliers and facilitates smoother transactions. Below are six essential terms widely used in the O-ring and industrial components industry:

• OEM (Original Equipment Manufacturer)
  Refers to manufacturers who produce parts or assemblies that are used in another company’s end products. When sourcing O-rings, clarifying “OEM grade” ensures compatibility with existing equipment standards and warranty requirements.

• MOQ (Minimum Order Quantity)
  The smallest order size a supplier will accept. In bulk procurement, understanding the MOQ is crucial for budgeting, inventory planning, and supplier negotiations, especially when balancing cost against storage constraints.
