Rubber Tapered Plugs

Rubber Tapered Plugs

Given their high pliability, rubber plugs are ideal for low-pressure isolation or vacuum-testing applications. Stocked sizes range from 5/16" tube ID through 4 3/4" tube ID.

The plugs are made of neoprene and are reusable. Temperature range: -45°F to +300°F (-43°C to 149°C).

Threaded Tapered Plugs

Threaded Tapered Plugs

A fast and simple way to stop leaks in tanks, pipes, and more. Threaded plugs seal with greater grip because of their threads, and not just by relying on friction.

Threaded plugs are manufactured with heat-treated alloy steel or stainless steel, and installed with a standard hex wrench or socket.

Non-Metal Plugs (Fiber / Wood)

Non-Metal Plugs (Fiber / Wood)

Available in wood or fiber (phenolic or micarta) these plugs are safe, easy to use, corrosion resistant, and easily removable for use in your heat exchanger, boiler or condenser.

Fiber / Wood plugs are easily installed with a gentle tap from a hammer and will expand by hydroscopic action to make an excellent seal while not damaging the tube sheet.

Anode Zinc Plugs

When you need to protect your boilers, pumps, tanks, pipelines and other pieces of equipment from corrosion, an anode plug with a zinc rod is the ideal solution.

Anode tube plugs absorb electrolytic action that would otherwise corrode your equipment, preventing costly repairs before they surface.
