Cherne 2" Muni-Ball Plug, 1/8" Bypass

The Cherne 2" Muni-Ball Plug (part #262-010) is a pneumatic bypass plug for 2" plumbing pipe with 1/8" NPT female bypass for controlled flow during testing. Rated for 22 PSI / 50 ft. head pressure at 40 PSI inflation. Natural rubber inflates to seal pipes from 1.88" to 2.25" ID. Ideal for residential DWV testing where you need flow control through the plug during the test.

Key Features

• 1/8" NPT F bypass — controlled flow-through during sewer and drain testing
• 22 PSI / 50 ft. head pressure — rated for sewer air and DWV testing
• Pneumatic inflation at 40 PSI — natural rubber seals round and out-of-round pipe
• Tether-bar compatible — holds to full head pressure with tether bar
• Natural rubber — durable construction for sewer environments

Applications

Sewer air pressure testing with controlled bypass flow, DWV code compliance testing, municipal sewer main isolation, storm drain testing, and pipe repair work requiring temporary flow control. The bypass allows water to pass through the plug during testing rather than building up behind it. Always follow Cherne inflation and back-pressure guidelines.
