The Cherne 2" Single-Size Plumbing Test-Ball (part #270-024) is a pneumatic test plug for DWV testing on 2" pipe — the most common residential drain and vent size. Natural rubber inflates to seal pipes from 1.90" to 2.25" ID. Rated for 13 PSI / 30 ft. head pressure at 40 PSI inflation. At just 3.5 oz, it’s one of the lightest pneumatic plugs in the Cherne line. Schrader valve, ring and chain assembly.

Key Features

Pneumatic inflation — natural rubber expands to seal round and out-of-round pipes
13 PSI / 30 ft. head pressure — rated for DWV and plumbing code testing
Schrader valve (tire-type) — inflate with any standard air source, field-replaceable
Ring and chain assembly — prevents draw-in during inflation
Natural rubber construction — excellent expansion memory for reliable sealing

Applications

DWV pressure testing for code compliance, residential and commercial plumbing inspections, stack testing, and sewer air tests. The pneumatic design seals quickly and conforms to out-of-round pipe — faster than mechanical plugs for multi-plug test setups. Always follow Cherne inflation guidelines and never exceed rated inflation pressure.
