$ 188.02Why Contractors Choose Cherne
Cherne has been the standard name in pipe testing and sealing equipment for decades. When a plumbing contractor, municipal crew, or pipeline company needs to isolate, test, or bypass a pipe section, Cherne is what they reach for. We carry the full product line — not a limited selection — so you can get every size and type from a single supplier.
Product Lines
Blocking Plugs (Test-Ball & I-Series)
Pneumatic plugs that create a complete seal for pressure testing, smoke testing, and construction isolation. Single-size and multi-size options from 4” to 24”. The I-Series covers extended ranges, reducing the number of plugs your crew carries.
Bypass Plugs (Muni-Ball)
Seal the pipe while diverting flow through a built-in bypass channel. Essential for sewer repair work where you can’t fully stop flow. Bypass sizes from 3/4” to 3” for residential through municipal trunk lines.
Mechanical Plugs (Gripper & Econ-O-Grip)
No inflation required. Hand-tighten for fast pipe sealing. Gripper plugs rated up to 17 PSI for drain testing. Econ-O-Grip for cost-effective low-pressure blocking.
Smoke Testing (Air-Loc)
Smoke generating devices for sewer system leak detection. Available in 60-second and 3-minute burn times.

FAQ
Do you carry the full Cherne line?
Yes. We carry Test-Ball, Muni-Ball, Gripper, Econ-O-Grip, Air-Loc, and accessory products. If you don’t see a specific Cherne item, call us — we can source it.
What’s the difference between Test-Ball and Muni-Ball?
Test-Ball plugs create a complete seal (blocking). Muni-Ball plugs seal the pipe but include a bypass channel that diverts flow around the work zone. Use Test-Ball for pressure testing; Muni-Ball for repair work where flow can’t be fully stopped.
Do you offer contractor pricing?
Yes. Call (866) 514-3684 for pricing on recurring or volume orders. We work with plumbing contractors, pipeline companies, and municipal crews nationwide.
