JRRT8 Brass 2 Piece Tube Plug (Ring & Pin)

The JRRT8 style plugs are ideal for sealing leaking tubes in condensers or heat exchangers. The two piece design has more sealing area and reduces the risk of damaging the tube sheet.

Please be sure to place the correct size plug in the tube and keep in mind that the tube plug and the tube material should always match. Order tube plugs by tube Outer Diameter and Gauge or Inside Diameter of tube, and tube metal. Special diameter plugs are available upon request.
