PTFE Back-up Rings

Back-up Rings are used in conjunction with O-rings in both static and dynamic sealing applications, PTFE Back-up Rings are used to prevent the O-ring from entering the clearance gap, when high pressures are exerted on the O-ring, its soft rubber material can be forced into the clearance gap causing the O-ring to extrude, PTFE Back-up rings keep the O-ring material from flowing into the gap which will prevent premature failure. PTFE Back-up Rings are made in single turn "scarf cut", Spiral "multi-turn", and solid "uncut"

Back-up Rings and PTFE products including Piston Rings, Washer, O-Ring, V-Seals, Balls, Valve Seats, Wipers, Wear Rings, Bearing , Rod Guide and custom parts in wide variety of polymer products in PTFE, PTFE Filled Compounds and many combinations of high-performance materials ideally suited for use in original equipment and industrial maintenance.

Precision Machined PTFE Back-up Rings & PTFE Seals are Custom Made to Order.
  • Seals, lips, cups, bearings, bushings, wear strips & other custom PTFE parts
  • Ball valve seats, piston rings, pipe and bellows
  • Diaphragms, insulators, lantern rings, V-rings, gaskets, washers, o-rings

PTFE products are commonly used in high temperature from minus 450F to +500F sealing applications.

PTFE O Rings are popular for use in axial static faces or flange applications which require a chemically resistant and non-compressible material and low-friction characteristics of PTFE. Its flow characteristics under stress, and lack of elasticity, are often a disadvantage in PTFE orings.

PTFE Seals material seals are the most chemically inert .It is resistant to most chemicals including acids, bases, oils, steam and other chemicals. It is also very tough and abrasion resistant. However the material is not easily compressed, and therefore may not seal as easily as some of the other polymers.

PTFE Piston Guides also called PTFE wear strips, align, stabilize and reduce radial movements of a cylinders piston rod from side loading,it provides guiding and bearing surfaces between rod and housing and prevents metal to metal contact between them,generally made in PTFE-Bronze Filled.

PTFE Bearing Bushing also known as Plain Bearings or Sleeve Bearings, are designed for use in numerous applications is a superior bearing material developed specially for machine tool ways, gibs and other sliding applications.

Turcite Wear Rings has function of a hydraulic wear ring is to guide the piston and piston rod of a hydraulic cylinder, absorbing transverse forces. At the same time, it prevents metal-to-metal contact, optimizing the performance of the sealing system.

PTFE Soft Packing size range 3mm to 10 mm square and roung section ,this soft flexible gasket and sealing material easily conforms to sealing surface imperfections with less torque than conventional materials. Expanded PTFE resists cold flow .
