Tire O-Rings

Technical Sealing Components for Professional Tire Systems

Double Safe Tire O-Rings are precision-engineered sealing components designed for tire assembly systems, rim sealing structures, and air retention applications across passenger, commercial, and OTR tire sectors.

DST provide full material classification, controlled hardness tolerance, and international standard dimensions to ensure consistent and reliable sealing performance.

1. Material Engineering Classification

We supply tire O-rings based on performance requirements rather than generic rubber types.

Standard Elastomers

NBR (Nitrile Rubber)

• Excellent oil resistance

• Good mechanical strength

• Cost-efficient solution

• Operating temperature: -40°C to +120°C

SBR

• Basic wear resistance

• Suitable for low-demand environments

CR (Neoprene)

• Balanced mechanical properties

• Moderate weather resistance

Performance Elastomers

EPDM

• Superior ozone & UV resistance

• Excellent aging resistance

• Operating temperature: -50°C to +150°C

HNBR

• Enhanced tensile strength

• Improved heat stability vs. NBR

• Suitable for heavy-duty & mining tires

IIR (Butyl Rubber)

• Extremely low gas permeability

• Optimized for air retention systems

High-Performance Elastomers

FKM

• High thermal stability

• Strong chemical resistance

• Operating temperature: up to +200°C

Silicone (VMQ)
