Specifications & Details
About PTFE Ring
Back-up Rings
PTFE back-up rings prevent extrusion of elastomeric O-rings under high pressure in hydraulic and pneumatic cylinders.
V-Ring Seals
PTFE V-rings provide effective sealing in rotary and reciprocating applications with minimal friction and long service life.
Chemical Sealing
Where elastomeric O-rings are incompatible with process fluids, PTFE O-rings provide a chemically inert alternative.
Custom Profiles
Non-standard ring profiles machined or moulded to your drawings. Filled grades for improved wear in dynamic applications.
Common Applications
PTFE Ring — Also Known as Teflon Ring
PTFE rings are also known as Teflon rings or Teflon seals. Teflon is the popular brand name for PTFE. Visanix Global supplies PTFE back-up rings, O-rings and V-rings in standard and custom sizes for hydraulic and chemical sealing applications across India.
