Bigger isn’t always better – except when it is. Enter MacrOrings®, Apple Rubber’s innovative solutions for large-scale sealing applications that are huge game changers in industries ranging from aerospace to renewable energy. In this blog, we’ll explore their unique features, applications, and why they’re the go-to choice for engineers tackling big sealing challenges.
What Are MacrOrings®?
MacrOrings® are large-diameter o-rings designed as an alternative to molding cost-prohibited diameter. MacrOrings by Apple Rubber provide effective sealing solutions for applications that require seals with larger inner diameters and cross-section greater than .070″. These aren’t your average o-rings; they’re precision-engineered bonded o-rings that maintain integrity and performance, comparable to a molded ring.
Key Features of MacrOrings®
1. Size Range: MacrOrings® can be manufactured with inner diameters ranging from 2″ to 500″
2. Material Versatility: Available in a wide range of elastomers, including silicone, nitrile, neoprene, fluorosilicone, viton, neoprene sponge, allowing for compatibility with various environments and substances
3. Precision Manufacturing: Despite their large size, MacrOrings® are produced with controlled tolerances, ensuring consistent performance and reliability
4. Seamless Construction: Unlike traditional spliced large o-rings, MacrOrings® are manufactured as a single, continuous piece, eliminating weak points and potential leak paths. Once a single vulcanized bond is used, it provides superior bond strength.
MacrOring Applications
MacrOrings® find their home in a variety of industries and applications where large-scale sealing is critical:
- Aerospace: Sealing large aircraft components and spacecraft modules
- Renewable Energy: Providing weather-tight seals for wind turbine nacelles and bases
- Oil & Gas: Sealing large-diameter pipelines and storage tanks
- Water Treatment: Creating watertight seals in large-scale filtration systems
- Construction: Sealing joints in large precast concrete structures
- Marine: Ensuring watertight integrity in submarine hatches and large maritime equipment
Choosing the Right MacrOring
Selecting the appropriate MacrOring for your application involves considering several factors:
- Operating temperature range
- Chemical compatibility
- Pressure requirements
- Installation method
- Expected service life
Our team of experienced engineers is always ready to assist in selecting or custom-designing the perfect MacrOring® for your specific needs.
