Product Overview

Cork Tube Plugs

Low-Cost Sealing for Heat Exchangers, Boilers & Condensers

Cork Tube Plugs offer an inexpensive, easy-to-use solution for sealing off Fin-Fan® / heat exchanger, boiler, and condenser tubes during maintenance, transport, or cleaning — keeping dust, dirt, and chemicals out where they don't belong.

Primary Use

Seals off tubes during shipment, cleaning, or maintenance — the easiest and lowest-cost method available for temporary tube closure.

Tube Identification

Industry experts use cork plugs to identify tubes during rework — a faster, simpler alternative to tagging, labeling, or diagramming tubes that need replacement or repair.

Cost & Availability

One of the lowest-cost tube plugs on the market — in-stock items ship within 24 hours. Easy to replace when needed.
