Features:

1. Ideal for corrosive applications and reducing the effect of product build-up
2. A good cost effective alternative to exotic materials
3. PTFE sleeve on all wetted surfaces of the rupture disk holder inlet
4. PTFE sleeve is available on the inlet only, and outlet can be Fluoropolymer Teflon Sintered (FS) coated
5. The ZOOK PTFE sleeved holder utilizes a Teflon encapsulated Viton O-Ring as standard. The O-Ring seal prevents the process media getting into contact with the bite-ring, this prolongs the high performance of the holder
6. PTFE sleeve is available for ZOOK flat seat series reverse acting disk holders in sizes from 1” (25 mm) through to 8” (200 mm)
7. The operating temperature range for the PTFE sleeve is -20ºF to 450ºF (-29ºC to 232ºC)
8. The ZOOK design utilizes a mechanical lock to engage Telfon for a rigid assembly
9. PTFE sleeves are not torque sensitive and follow standard holder torquing procedures
10. The PTFE sleeve option can be used for most burst pressure ranges as shown on the data sheets for ZOOK rupture disks
11. Teflon liners are available to minimize product build-up and corrosion on rupture disk
