OATEY 272949 – Frequently Asked Questions
1) What pipe types and sizes does the Cherne 6 inch T-Handle Gripper plug fit?
The 6 inch Cherne Gripper plug is sized for 6 in. (150 mm) nominal pipe, and at that size it's built for concrete, clay, and SDR 26 and 35 pipe. The larger 15 and 18 inch Gripper plugs in the same family are sized for concrete and clay only, so the 6 through 12 inch range is the one that covers plastic sewer pipe.
2) How much back pressure can the Cherne 6 inch Gripper test plug hold?
Rated to 10 psi (0,7 bar) of back pressure, which works out to 23 ft. (10 M) of head. If your test column will stand taller than 23 feet above the plug, this is the wrong plug for that riser.
3) What is the 1/4 inch bypass on this Cherne test plug used for?
The bypass is a 1/4 in. male connection through the body of the plug, so you can run a hose or gauge line through a plugged line while it stays sealed, fill or drain the test column, or bleed pressure off before you pull the plug. Cherne Gripper plugs are offered with or without the bypass; model 272949 is the bypass version.
4) Can a Cherne Gripper plug be left in a line for an extended period, or is it test-only?
It can stay in for long-term applications. The body is heavy-duty aluminum and the seal is a chemical-resistant neoprene O-ring, so it isn't limited to a short pressure test the way a light inflatable bag is. Keep the line within the 10 psi back pressure rating for the whole time it's in place.
5) What Oatey part number do I order for the 6 inch Cherne T-Handle Gripper plug with bypass?
Order Oatey 272949. That's the 6 in. Cherne T-Handle Gripper plug with the 1/4 in. male bypass. The same Gripper plug is also made without a bypass, so specify the model number rather than just the size if you need the bypass port.
6) Will the neoprene O-ring on this plug hold up to sewage and cleaning chemicals?
The Gripper plug uses a chemical-resistant neoprene O-ring, which is why it's rated for long-term use in a line rather than just a quick air test. The plug body itself is aluminum.
