Tube Plugs for Heat Exchangers
Plug leaky internal tubes in heat exchangers with these two-piece ring and pin sets. Insert the ring into the tube and hammer the pin into the ring for a secure seal. If you do not know the tube OD or wall thickness, measure the tube ID and select the closest ring OD.

Screw-Plug Immersion Heaters for Oil and Coolant
To heat oil and coolant without creating hot spots and damaging the heating element, these heaters have a lower watt density than heaters for water or chemicals. They install into threaded container openings or pipe couplings to quickly and efficiently heat liquid through direct contact.
Heaters without temperature control require a temperature switch or controller (sold separately) to regulate heat output.
Heaters with an adjustable thermostat automatically turn on when the temperature drops below the set temperature and off when it rises above the set temperature. Adjust the set temperature with the dial.
Incoloy heating elements are more corrosion resistant than steel heating elements.
Note: Fully immerse the heating element in liquid to prevent heater failure. These heaters install through threaded container openings or pipe couplings.
