HNBR O-Rings - 90 Shore AED

HNBR O-Rings - 90 Shore A - AED (Anti Explosive Decompression) and RGD (Rapid Gas Decompression is an important O-ring when used in the oil and gas industry. Because the O-ring is AED and RGD approved, cracks or tears will not occur in the O-ring when there is trapped gas that expands due to rapid pressure drop. If this were to happen it could result in seal failure and system malfunctions. Due to its special composition and certifications such as ISO 23936-2, NORSOK M-710 and NACE TM0297 the O-ring HNBR AED can withstand severe pressure variations. They keep the risk of gas absorption and blistering to a minimum which makes them a reliable seal. The HNBR O-Rings - 90 Shore A - AED is perfect when used in drilling rigs, valves, compressors and high-pressure pipelines as safety and reliability is indispensable in these places.

The difference between HNBR and NBR O-rings

Despite the fact that HNBR and NBR are very similar, there are some differences and advantages. HNBR is a hydrogenated version of the NBR which means its thermal stability (-40°C to 150°C), chemical resistance and abrasion resistance are significantly improved over the NBR. Although the NBR is less resistant to challenging temperatures, oils and strong chemicals, the HNBR remains intact longer even when exposed to fuels, hydraulic fluids and rapid pressure change (RGD). This makes HNBR one of the better options when used in oil/gas plants or industrial machinery.


Why 90 Shore A hardness?

The HNBR O-Rings - 90 Shore A - AED have a hardness of 90 Shore and are thus designed to be one of the best to withstand high pressures, temperatures and heavy loads. The increase in hardness ensures that the HNBR O-Rings - 90 Shore A - AED remain dimensionally stable and will not deform under mechanical stress. This is an important factor in the oil/gas and hydraulic systems. Thanks to their pressure resistance, they can handle high loads without cracking or stretching. In addition, their abrasion resistance results in a longer service life (even with intensive use) and maintains performance even in temperatures from -40°C to 150°C.


What happens during rapid gas decompression?

During rapid gas compression standard elastomers absorb gas when under high pressure. As soon as the pressure drops suddenly the trapped gas expands which can then lead to blistering, cracking and eventual seal failure. This is common in the oil and gas industry where fluctuation in pressure is unavoidable. HNBR O-Rings - 90 Shore A - AED are designed to prevent damage like this. Their low gas permeability and strong structure allow them to withstand violent pressure variations without cracking. This is a flawless product when used on drilling rigs, compressors and high-pressure pipes.


International standards AED resistant O-Rings

HNBR O-Rings - 90 Shore A - AED must comply with strict international regulations to ensure reliability and safety. Certifications such as NORSOK M-710 is a test for resistance to RGD while ISO 23936-2 confirms suitability in the oil and gas industry.
