O-rings and seals are used in a wide range of industries to help you tightly seal the connections in pipes, tubes, and other elements of complex hydraulic and pneumatic systems.
BS EN 3663 is a European Standard on aerospace series that discuss O-ring in rubber NBR. The main aim of BS EN 3663 is to provide static sealing applications where simple, cost-effective leak-tight performance is required.
BS EN 3663 specifies the characteristics for O-rings in rubber NBR, 75 IRHD, according to MIL-P-83461, for aerospace applications.
Temperature range: – 55°C to + 135°C.
BS EN 3663 on O-rings in rubber NBR for aerospace applications is useful for:
Nitrile rubber (NBR) O-rings are one of the most commonly used sealing elastomers due to their resistance to petroleum-based fuels and lubricants.
An O-ring seal is one of the most widely used seals to block the clearance gap in the industry today. These are used in applications, ranging from garden hose couplings to aerospace or oil and gas duties. Machinery made to take to the seas and skies require O-rings and seals that must be relied on and not fail in the most critical of times.
In this regard, BS EN 3663 specifies the configuration, dimensions, tolerances and visual inspection of the appearance of the material used for making O-rings for aerospace applications.
BS EN 3663 covers the designation, marking and technical specifications of O-rings in rubber NBR that help to manufacture good quality products.
As a result, if you are an O-ring manufacturer, you can use BS EN 3663 to improve the production of these applications and build the greatest quality sealing products that include all of the attributes that make them ideal for use in aerospace applications.
