Make Boiler Repairs Faster & Easier - Reduce Downtime, Eliminate Welding, Save Money...

Reliably plug boiler tubes without welding or time consuming pre-heating and post weld stress relieving and the weld inspections that go with it.

EST's Pop-A-PlugŪ Boiler Plugs are made for fast, easy installation. Just position the plug in place and set with an easy to use hydraulic tool ram. The unique breakaway controls installation force to ensure a positive seal without damage to tube, tube-to-tubesheet joints. You get a reliable, leak-tight seal in just minutes. Repairs go faster, and expensive downtime is substantially reduced. No welding also means no waiting for inspections.
