O-Rings Series
O-Ring Series – Engineered for Reliability Across Industries
The Foundation of Industrial Sealing: Precision O-Ring Series
At Qalalam, we understand that seal failure leads directly to costly downtime and system compromise. Our comprehensive Industrial O-Ring Series is engineered not just to fit, but to perform under the harshest conditions—from the dynamic motion of hydraulic cylinders to the aggressive chemicals in processing plants. We offer a full selection of precision seals built to rigorous international specifications, ensuring total reliability for your critical systems globally.
Compliance & Standards:
Every O-ring in our inventory is manufactured with tight tolerances and tested for dimensional accuracy, conforming strictly to global industry standards:
-
Metric Series: Adhering to standards such as ISO 3601
-
Inch/Imperial Series: Meeting the widely recognized AS568 aerospace standard.
Comprehensive Material Selection for Any Environment
Selecting the correct elastomer is paramount for longevity. We offer an extensive range of high-performance compounds, formulated to resist specific media, temperature, and pressure demands:
| Material Name | Key Properties | Ideal Industrial Application | Temp Range (Approx.) |
| FKM (Viton®) | Excellent heat and chemical resistance, low compression set. | Aerospace, Oil & Gas (Petroleum, Fuels), Chemical Processing. | $-20^ to +205^ |
| HNBR | Superior abrasion, tear, and heat resistance compared to NBR. | Automotive (AC systems), High-Pressure Hydraulics, Sour Gas Service. | $-30^ to +150^ |
| Nitrile (NBR) | Cost-effective, good resistance to non-polar solvents. | General Industrial, Hydraulic Fluids, Oils, Water. | $-40^ to +120^ |
| EPDM | Excellent resistance to steam, water, and polar solvents. | Automotive (Brake Fluid, Cooling Systems), Water Treatment. | -50^ to +150^ |
| Silicone | Stable across extreme temperatures, high flexibility. | Food & Beverage (FDA compliant), Medical Devices, Extreme Temperature Cycles. | -60^ to +200^ |
| FFKM & PTFE | Ultimate chemical resistance, ultra-high purity, low friction. | Semiconductor, Pharmaceutical, Aggressive Acid/Caustic Service. | Up to +315^ |
