The Poly-Flo Natural 88-P is a flexible polyethylene thermoplastic tubing designed for low-pressure aircraft pneumatic and instrument systems. It is manufactured from high molecular weight polyethylene, providing good flexibility, chemical resistance, and resistance to environmental stress cracking.

The 88-P (1/2") size is the largest in the standard Poly-Flo range and is commonly used for instrument air lines, pneumatic routing, and light fluid transfer applications where low weight and easy installation are required. It is typically supplied in natural (translucent) color and cut to length.

This tubing is intended for use with Nylo-Seal or compatible compression fittings, and is widely used in general aviation for pitot-static, vacuum instrument, and pneumatic accessory lines.
