Three-Seal Joint Series

Three-Seal Joint Series

Fixed outer diameter of rigid piping! A three-seal type joint that is difficult to slip and can be securely fixed.

We would like to introduce the "Three-Seal Joint Series" handled by Hagi Tech. The PTFE-made abacus-type seal fixes PTFE or PFA tubes from the outer diameter by crimping. However, in the case of glass or stainless steel tubes, unlike resin tubes, there are instances where it cannot bite in and may slip out. The three-seal joint sandwiches two FKM O-rings with a PTFE ring to secure the outer diameter of hard piping, making it less likely to slip and providing a more secure fixation compared to traditional PTFE abacus-type seals. 【Lineup (Excerpt)】 ■ PTFE Three-Seal Type I Joint ■ PTFE Three-Seal Type L Joint ■ PTFE Three-Seal Type T Joint ■ PTFE Three-Seal Half Male Joint Type I ■ PTFE Three-Seal Half Female Joint Type I *For more details, please refer to the related link page or feel free to contact us.
