Available in both internal seal and flanged seal configurations, you can get the expandable plug that fits your exact product needs. If you're working on a unit that creates a vacuum, our flanged seal expandable tube plug has a flange on the outer side of the plug that allows it to sit flush on the tubesheet, preventing any inward movement. Conversely, if your desired setup includes placing a tube plug at an exact location inside the tube, our internal seal plugs are ideal.

Both internal and flanged seal expanding plugs are available in single- or double-seal configurations. For maximum sealing effectiveness, we recommend our double-seal expanding tube plugs. All expansion plugs are made of neoprene and rated to 150 PSI when installed properly. Safety lanyards can be installed (at an additional cost) to assure operator's protection.

Grade K-2247-CF, ASTM-BC 412 45+/-5 Durometer hardness

Note: Always 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.
