Two-Piece Metal Tube Plugs


Minimize Tube Sheet Damage with Custom Cut Two-Piece Plugs

Product Features

• Minimizes tube sheet damage, preventing expensive repairs
• Custom cut to your tube's I.D. for exact fit
• Available in more than 20 metals and any size upon request

Product Description

USA Industries' Two-Piece Tube Plugs offer more sealing compared to one-piece tapered tube plugs, and are designed to minimize damage to the tube sheet when sealing off leaky boiler, condenser and Fin-Fan® / heat exchanger tubes. The two-piece plugs work by utilizing a ring that's parallel to the tube on the outside, but tapered on the inside, giving even expansion to the ring and a longer contact point to seal, minimizing points of failure.

Easy and quick installation--place the ring inside your boiler, condenser or fin-fan / heat exchanger, and drive the tapered pin into the ring (custom-cut to your tube's I.D.), causing the ring to expand and give you a 360° seal for the length of the ring. Note: You MUST provide us with the exact I.D. of your tube so we can turn down the outer piece of the two-piece tube plugs for an exact fit.

It is good practice to install rings and pins that are the same as or a compatible material to the tube to be plugged. The tube plugs are available in an array of materials to suit your needs: brass, carbon steel, 316 stainless steel, 416 stainless steel, and aluminum (more than 20 different metals available upon request).

USA Industries has been a leader in offering tube plug solutions to users in the oil & gas, chemical and power industries for more than 2 decades. We have more than 500,000 tube plugs in stock and ready to ship, and our production capabilities exceed 5,000 plugs per day, more than 20 materials and any coatings you may require.

A SPECIAL WORD OF CAUTION: USA Industries highly recommends you use our One Rev Internal Tube Cutter to puncture the tube before installing any plug to ensure that pressure cannot build up in the tube and cause the plugs to loosen or blow out.
