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.
