Cherne 270040 Rubber Test Ball Pipe Plug for 4 in. Systems

The Cherne 270040 Rubber Test Ball Pipe Plug is an essential tool for plumbing professionals and DIY enthusiasts alike. Designed specifically for 4 in. nominal size pipes, this test ball plug is perfect for testing DWV systems at pressures up to 13 PSI or 30 ft. With its robust construction, it ensures reliable performance during critical testing phases.

One of the standout features of this test ball plug is its natural rubber body, which provides excellent expansion capabilities. This means that it can effectively seal both round and out-of-round pipes, making it a versatile choice for various plumbing applications.

The inflatable design of the Cherne test ball allows for easy insertion through a test tee, making it ideal for hard-to-access openings.

The plug utilizes a standard tire air fitting for easy connections, ensuring that you can quickly inflate and deflate as needed.

Safety is a top priority with the Cherne 270040, which is why it comes equipped with a ring and chain assembly. This assembly helps prevent the plug from being drawn into DWV systems during tests, providing peace of mind while you work. The zinc-plated steel chain and ring handle acts as a reliable anchor, preventing the plug from sliding down a line and ensuring that it stays securely in place.

In addition to its practical features, the natural rubber construction of this plug offers excellent memory, allowing it to return to its original shape after use. This durability ensures that the plug can withstand repeated use without losing its effectiveness. It fits easily through test tees, sanitary tees, floor drains, and other tight situations, making it a must-have tool for any plumbing job.
