ptfe bellows
DEKOMTE supplies a range of PTFE expansion joints for use in special chemical and industrial applications. The two main options are:
Low pressure Type R-LD
High pressure Type R-HD
PTFE multi-laminated tubes that ensure an absolute minimum porosity and a homogeneous wall-thickness, are transformed again under temperature and pressure to special high-quality bellows, with a high vacuum and pressure resistance, even during a long period of operation.
