Cherne ® 10" T-Handle Gripper ® Plug with 3/4" Bypass

The Cherne 10" T-Handle Gripper with Bypass (part #272-965) is a heavy-duty aluminum mechanical test plug with 3/4" NPT male bypass for 10" underground pipe. Rated for 10 PSI / 23 ft. head pressure. Fits 10" concrete, clay, SDR 26, and SDR 35 pipe (usage range 9.8"–10.3" ID). At 15.5 lbs, the aluminum body keeps weight manageable for field crews. Chemical-resistant neoprene O-ring and zinc-plated steel T-handle.

Key Features

• T-handle mechanical expansion — high-torque sealing for concrete, clay, and SDR pipe
• 3/4" NPT M threaded bypass — controlled flow during testing without full shutoff
• 10 PSI / 23 ft. head pressure — rated for sewer air pressure tests
• Chemical-resistant neoprene O-ring — handles sewer gas and chemical exposure
• Heavy-duty aluminum body — corrosion-resistant and lighter than cast iron

Technical Specifications

Applications

Sewer air testing on 10" mains, storm sewer isolation, bypass plugging during municipal line repairs, and construction-phase testing on new 10" pipe installations. Note: the 10" and 12" models are rated at 10 PSI — lower than the 6" and 8" models — due to the larger pipe diameter.
