Heat Exchanger Products Corporation manufactures Silicone Condenser Tube Plugs in Double and Single sizes to fit 5/8" to 1 1/4" size tubes. The plug consists of a metal or non-metal nut and bolt, a durable, heat resistant silicone and a washer and collar made from a non-water soluble plastic called Hytrel.

These silicone tube plugs are ideal for use in fresh or salt water applications and can be used for a temporary fix or to seal a tube permanently.

Compounded of extruded vulcanized silicone rubber, these plugs provide long life at high temperatures and an almost unlimited life span at normal operating temperatures.

We also offer pre-set Torque Wrenches set to 33 in. lbs. for easy installation.
