Key Features
1
High Corrosion ResistanceThe QS-1/2-12-I is made from chemically nickel-plated brass, ensuring high corrosion resistance (CRC 3) and chemical resistance, making it suitable for demanding industrial environments.
2
Self-Sealing ThreadsEquipped with self-sealing PTFE-coated threads, this fitting can be reused up to five times without the need for additional sealing components, reducing maintenance and downtime.
3
Rotatable DesignThe fitting is rotatable, allowing for easy installation and minimizing the risk of damage to the tubing. The stainless steel retaining claw securely holds the tubing without damaging its surface.
4
Wide Temperature RangeSuitable for pneumatic applications with a temperature range up to 80°C, making it versatile for various industrial settings.
