## Product Summary

PLF pneumatic fittings are **female elbow push-to-connect connectors** designed for 90-degree tube-to-thread connections in pneumatic systems.

Featuring an **internal (female) threaded port**, the PLF fitting connects tubing to a male threaded component while allowing directional air routing in compact layouts.

The one-touch push-to-connect design enables fast installation without tools, ensuring secure and leak-free connections. Such quick-connect fittings use internal gripping teeth and O-rings to achieve tight sealing and easy operation.

With a **90° elbow structure**, PLF fittings are ideal for space-constrained installations in automation systems, machinery, and air distribution networks.

**OEM and ODM customization services are available** for thread standards (BSP/NPT/Metric), tube sizes, materials, and branding.
