What is BS EN 3748 - Dimensions of O-ring grooves for aerospace applications about?
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 3748 is a European Standard on aerospace series that discuss O-ring grooves. The main aim of BS EN 3748 is to provide static sealing applications where simple, cost-effective leak-tight performance is required.
BS EN 3748 specifies the dimensions of grooves for use with O-rings according to EN standards for aerospace applications:
- Radial sealing: rod or bore mounted O-rings
- Axial sealing: internal or external pressure source
Who is BS EN 3748 - Dimensions of O-ring grooves for aerospace applications for?
BS EN 3748 on the dimensions of O-ring grooves for aerospace applications is useful for:
- The aerospace and defence industry
- Manufacturers of aerospace fluid systems and components
- Designers of sealing rings
- Manufacturers and suppliers of O-ring grooves
- Product design engineers
- Testing agencies involved in the inspection of aerospace products
- Aeronautical engineers
Why should you use BS EN 3748 - Dimensions of O-ring grooves for aerospace applications?
An O-ring seal is one of the most widely used seals to block the clearance gap in the industry today. It is also known as a toroidal seal. O-ring seals 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 3748 specifies the configuration, dimensions, tolerances, designation and drawing presentation for:
- Radial sealing – Rod housing: Configuration code A
- Radial sealing – Bore housing: Configuration code B
- Axial sealing for internal pressure: Configuration code C
- Axial sealing for external pressure: Configuration code D
As a result, if you are an O-ring groove manufacturer, you can use BS EN 3748 to improve the production of these applications and build the greatest quality grooves that include all of the attributes that make them ideal for use in aerospace applications.
