Bohlender GL45 Bottle Cap with NPT Port

To the NPT port, connect 1/4" outer diameter fluororesin tubing with the included PTFE fitting, 4mm and 6mm outer diameter fluororesin tubing with separately sold fittings, and 6.5mm and 8.5mm inner diameter corrugated (bellows) tubing with a corrugated tube fitting.
The included air valve (for UNF ports) also balances the negative pressure inside the bottle while preventing the inhalation of contaminants.
Since each tube from the pressure or suction source passes through the body and the height inside the bottle can be freely adjusted, it is suitable as a liquid or gas supply/discharge container or a bottle cap for bubble traps.
There is an 8mm high space on the side of the yellow cap where you can write or attach a label with a permanent marker.
The body is made of PTFE with a Viton O-ring on the inside.
The cap is made of polyphenylene sulfide (PPS).
When attaching or removing the cap, the cap can be rotated freely while preventing the tubing already connected to the port from twisting.
The cap is heat resistant up to +200°C.
