Dechengwang separately lists machined PTFE bellows; provide the movement, interfaces and part drawing for the selected component.
View product →Product overview
Dechengwang lists custom PTFE rings as a distinct machined-part range; define the actual geometry and material rather than assuming one standard seal profile.
Supply the seal or groove drawing, medium, movement, operating conditions and existing material reference. Ask for the actual offered grade and dimensional and material information for comparison with the particular sealing task. Request the current catalogue or drawing for this item, and confirm the offered configuration and supporting documents with the company before specifying an order.
