### What is a figure 8 blind?

A figure 8 blind is a type of pipe fitting used in piping systems to temporarily block or seal off a pipe. It is shaped like the number 8 and is designed to be easily installed and removed without the need for tools.

### How does a figure 8 blind work?

A figure 8 blind works by wrapping around a pipe and securing in place with bolts. The design of the figure 8 blind allows it to create a tight seal, preventing the flow of fluids through the pipe. This can be useful during maintenance or testing procedures when a section of pipe needs to be isolated from the rest of the system.

### When is a figure 8 blind used?

A figure 8 blind is typically used in situations where a temporary blockage or seal is needed in a piping system. This could be for maintenance purposes, such as when a section of pipe needs to be removed or replaced. Figure 8 blinds are also used during pressure testing to isolate specific sections of the system.

### How is a figure 8 blind installed?

To install a figure 8 blind, it is wrapped around the pipe at the desired location and the bolts are tightened to secure it in place. The figure 8 blind should be positioned so that it creates a tight seal and prevents any leaks. Once the installation is complete, the piping system can be safely operated without flow through the section blocked by the blind.

### What are the advantages of using a figure 8 blind?

One of the main advantages of using a figure 8 blind is its ease of installation and removal. Because it does not require any tools, it can be quickly installed in emergency situations or during routine maintenance procedures. Figure 8 blinds are also cost-effective and reusable, making them a practical choice for temporary pipe sealing applications.
