The PTFE-made soroban-type seal fixes PTFE or PFA tubes by crimping them from the outer diameter!
We offer a "three-seal joint" structure that securely fixes slippery hard pipes by sandwiching O-rings and PTFE rings. In the case of glass or stainless steel pipes, unlike resin tubes, the soroban-type seal cannot bite in, which can lead to slippage and disconnection. The three-seal joint fixes the outer diameter of hard piping by sandwiching two FKM O-rings with a PTFE ring, making it less likely to slip and providing a secure hold compared to traditional PTFE soroban-type seals. 【Product Lineup】 ■ NR1089 PTFE Three-Seal Type I Joint ■ NR1090 PTFE Three-Seal Type L Joint ■ NR1091 PTFE Three-Seal Type T Joint *For more details, please download the PDF or feel free to contact us.
