One-touch coupler for airtightness testing (FD type)

You can connect to the male thread with a one-touch connection. The work that previously required wrapping seal tape and tightening with tools can now be done with a one-touch connection. Disconnection is also one-touch. *Fluid supply and exhaust will need to be handled separately. ■Features 1. The rear end of the one-touch coupler locks and seals by being pushed into the male thread work side. 2. The release mechanism at the rear end of the one-touch coupler is slid to unlock. 3. It is also excellent in waterproof, water resistance, and chemical resistance. *You can download the catalog from the download button below.
