## Product Summary

KL-PG pneumatic fittings are reducing union quick-tight connectors designed for connecting pneumatic tubes of different diameters.

As part of the KL series quick-tight fittings, KL-PG enables fast installation and secure sealing without complex tools, improving efficiency in industrial automation systems.

The reducing structure allows two tubes with different sizes to be connected directly, making it ideal for system transitions and tubing size adjustments.

The fitting features a nickel-plated brass body, providing excellent corrosion resistance, durability, and long service life.

Quick connect technology allows instant tube insertion and locking, ensuring stable and leak-resistant performance.

OEM and ODM customization services are available for tube size combinations and branding requirements.
