PTFE Bellows

PTFE bellows are used as balancing elements between engineering parts, which is widely used in chemical, food and medical appliances. The different geometres of the folds highly flexible or pressure-resistant versions can be designed and manufactured to reach higher flexibility or compressive strength.  External and internal Pressure, number of runs and all -closed/ all-open lengths are the critical factors to consider in designing a bellow.
