The Rico "Plug-it" Tube Plug offers a new and inexpensive way to seal leaking heat exchanger tubes safely, and with the minimum of fuss.
The two components that make up the tube plug (main body and a nickel plated expansion pin) are all produced from advanced polymer materials. This combination of materials together with the unique design of the products results in the ability to withstand temperatures of up to 150° C and working pressures of up to 130 psi.
How Does It Work?
The external dimensions of the plug body are designed to be an interference fit in the tube end. The internal profile incorporates two main attributes:-
This unique design ensures that any increase in pressure within the channel resulting from the operation of the heat exchanger can only drive the expansion pin further in, once again resulting in an improved seal with the tube bore. The specific materials used for the plug body and expansion pin can be tailored to suit the particular environmental conditions of the host heat exchanger. The particular grades of polymer which have been chosen as standard are suitable for a wide range of mediums including fresh water, seawater, oil, Freon and many other chemicals and solvents.
Manufactured to fit condenser & heat exchanger tubes from 5/8" to 1 1/4" ID. The plug is designed to withstand a range of temperature, vibrations and pressures up to 150 psi.
It features an over-sized washer that fits over the tube opening and a double rubber body that adjusts to fit the tube wall giving a tight fit. Suitable to fit tubes that have a larger tube ID where the tube has been expanded into the tube-sheet than the rest of the tube.
Available in brass, stainless steel, titanium, bronze and monel.
