EPDM/PTFE STRESS SAVER GASKETS T*0(equivalent to Asahi gasket)

Stress saver gasket offer a unique double convex ring design that gives optimum sealing with only one third the torque commonly required with flat faced gaskets. Asahi offers EPDM gaskets from 1/2" to *2"; PTFE-bonded EPDM gaskets in sizes from 1/2" to *2"; and PVDF-bonded EPDM gaskets from 1/2" to *0".

Features and Benefits

• EPDM - durometer A, hardness *5 - *8
• PTFE or PVDF-bonded EPDM for maximum corrosion resistance
• Perfect sealing at low bolt tightening torque ratings; longer gasket life
• Ideal for plastic piping systems, as well as metal or plastic-lined metal systems
• Working temperature:
  • EPDM: - *0 - **5º F
  • PTFE-bonded: - *0 - **0º F
  • PVDF-bonded: - *0 - **0º F
• Approximately one third bolt tightening torque ratings as compared with flat or envelope type gasket
• Thickness of bonded materials
  • PTFE: All Sizes: 0.**6" (0.4mm)
  • PVDF:Sizes 1/2" - 2": 0.**6" (0.4mm)
  • PVDF:Sizes 3" - *0": 0.**0" (0.5mm)
• PTFE-bonded gasket excellent for most corrosive chemicals
• PVDF-bonded gasket is ideal for the following:
  • Semi-conductor industry, because of its purity
  • Aggressive chemicals (strong acids, bases, halogens, etc.)
  • Media that generates any volatile gas (PVDF gas permeation is only 1/*0 of PTFE)
• Both the PTFE and PVDF-bonded gaskets employ a proprietary laminating process for bonding to EPDM, providing the greater elasticity required for lower sealing torques
