By using the newest technologies in silicone rubber, Hepco proves their dedication to providing their clients with high-performance, cost effective, condenser tube plugs. Silicone rubber is the material of choice over black rubber and metal for low pressure condenser and heat exchanger tube plugs.

There are several reasons why Hepco recognizes silicon rubber as a superior material for their condenser tube plugs. At the top of their list is its superior performance when it comes to flexibility and heat resistance.

Silicone rubber retains its natural flexibility and resilience across a wider temperature range. In fact in almost all cases silicone rubber will seal better because of its remarkable flexible qualities and excellent resistance to extreme temperatures. This alliance of flexibility and extreme temperature resistance is critical in the make up of a strong and reliable condenser tube plug. These properties allow Hepco to re-use their plugs and still achieve the same seal.

Hepco understands that longer staying power means less down time replacing plugs and less money spent on new plug replacement. At normal operating temperature silicone rubber offers an almost unlimited lifespan in service. Silicone rubber’s resistance to deterioration due to chemical compounds in standing water means Hepco’s condenser tube plugs will be sticking around longer to perform their critical functions.

Condenser tube plugs made from other materials such as rubber show less promising performance and durability. Rubber has a carbon to carbon backbone which means a condenser tube plug made from this material leaves it susceptible to the ozone, UV heat and other ageing factors that Hepco’s silicone rubber condenser tube plugs are able to withstand. Rubber can also fail due to cracking or rotting. Metal condenser tube plugs can distort the tube or tube sheets. Hepco’s plugs avoid the dangers of corrosion often experienced with metal condenser tube plugs because no metallic parts touch the inside of the tube.
