PTFE Sleeved Holder Inlet

The 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 outer seal prolonging the life of the holder. ZOOK’s unique double seal prolongs the life expectancy of the holder.
