Description
The Cherne 8"-12" Big-Mouth Plug with 4" Bypass (part #374-088) is a pneumatic bypass plug with an oversized 4" opening for maximum flow-through during sewer testing on 8" to 12" pipe. The Big-Mouth design provides more bypass capacity than standard Muni-Ball plugs — critical when flow volumes are too high for smaller bypass fittings.
Key Features
- 4" bypass — controlled flow-through during testing
- Pneumatic inflation — natural rubber seals round and out-of-round pipe
Applications
Municipal sewer air pressure testing, storm drain isolation, large-diameter pipe testing during construction and repair, and compliance testing on trunk mains. Always follow Cherne inflation and back-pressure guidelines.
