Coilhose Pneumatics PTL0503-500K Polyurethane Tubing

Product Description

The COILHOSE PNEUMATICS PTL0503-500K is a black polyurethane pneumatic tubing supplied in a 500-foot coil and sold in 1-foot increments with a 25-foot minimum cut length. It features a 3/16-inch inside diameter and a 5/16-inch outside diameter, with a wall thickness of 1/16 inch. Rated to a maximum working pressure of 93 psi, this tubing is well suited for compressed air distribution, pneumatic tool feed lines, and light-duty fluid transfer in shop and industrial environments. A hardness rating of 85 Shore A gives it good abrasion resistance while retaining the flexibility needed for routing around equipment frames and machinery.

This tubing is used in residential shops, commercial facilities, and light industrial settings where a compact-diameter air line is required. Common applications include pneumatic automation, instrumentation lines, spray finishing equipment, and general compressed air circuits. Contractors and maintenance technicians typically cut lengths to suit specific routing runs. The 500-foot coil format supports larger installations or service fleets that need consistent tubing stock on hand.

Key Features

• Polyurethane construction delivers flexibility and resistance to abrasion, kinking, and many shop chemicals
• 3/16-inch ID and 5/16-inch OD with a uniform 1/16-inch wall thickness for consistent flow and fitment
• Rated to 93 psi maximum working pressure for compressed air service
• 85 Shore A hardness balances durability with ease of routing
• Black color for standard industrial identification and UV resistance in typical shop conditions
• 500-foot coil length reduces splicing needs on extended runs

Compatibility

Designed as a general-purpose pneumatic tubing replacement or new-installation supply for compressed air systems using push-to-connect or barb fittings sized for 3/16-inch ID and 5/16-inch OD tubing.

Installation Notes

Installation is typically performed by maintenance technicians or pneumatic system contractors. Depressurize and lock out the air supply before cutting into an existing line or replacing tubing. Use a sharp tubing cutter or a clean shear cut to ensure a square end for proper fitting engagement. Verify that all fittings and connectors are rated for the system working pressure and compatible with polyurethane tubing before final assembly.
