Extruded Rubber Double Bulb Seals And Gaskets
Double Bulb Seals, one of the popular rubber seal 
profiles, can be extruded bypassing the Silicone 
rubber material through an extrusion machine. The 
elastomer used is non-toxic, non-reactive,non-
leaching and pyrogen-free. Silicone rubber bulb seals 
are resistant to both high and low temperatures. They 
are also tolerant towards Weathering, UV and Ozone. 
The process of extrusion gives our clients an 
opportunity to customize a seal as per the 
requirement of the application. They can choose the 
material based on the seal’s closure force 
requirement, attachment requirements and the 
environment in which it has to be installed. The clients 
also have the privilege to choose the shape, profile 
and color of the seal. Metal detectable extruded 
rubber double bulb seals can also be customized as 
per industry requirements.
