Efficient Sealing for Standard Raised-Face Flanges
Designed for standard industrial applications, our IBC gaskets (also known as ring gaskets or raised-face gaskets) offer a reliable, cost-effective sealing solution, these gaskets sit completely inside the flange bolt circle.
Because they focus all of the bolt clamping load directly onto the raised sealing face of the flange, they achieve a tight, secure seal with lower torque requirements, making them the default choice for everyday utility piping.
Key Feature Breakdown:
- Inside Bolt Circle (IBC): The gasket ring drops directly inside the bolt circle, resting flat against the raised face. This profile allows for incredibly fast drop-in installation without needing to completely disassemble the flange bolts.
- Optimised Sealing Pressure: Because the surface area is smaller than a full-face gasket, the bolt load is highly concentrated. This results in superior surface compression and excellent gas-tight sealing performance.
- Wide Compatibility: Perfectly sized to comply with standard ASME B16.21 dimensions for Class 150 and Class 300 flanges.
