Coilhose Pneumatics PTL0503-500B Polyurethane Tube 500 Ft

Product Description

The COILHOSE PNEUMATICS PTL0503-500B is a polyurethane pneumatic tubing sold in a 500-foot coil, designed for use in compressed air and fluid transfer lines in industrial and commercial pneumatic systems. With a 3/16-inch inner diameter and 5/16-inch outer diameter, this tube has a 1/16-inch wall thickness and a maximum working pressure rating of 93 psi. The blue color coding aids in line identification during installation and service. Licensed pneumatic system technicians, maintenance mechanics, and industrial plumbers use this tubing when building or repairing push-to-connect and barb-fitting pneumatic circuits.

This tubing is suited for light- to medium-duty pneumatic applications including instrumentation lines, automation equipment, air tool feed lines, and fluid conveyance in manufacturing or workshop environments. The polyurethane construction resists abrasion and retains flexibility across a range of temperatures, making it appropriate for both fixed routing and flexible-arm applications. It is sold by the foot in 25-foot minimum cut lengths from the 500-foot total coil, allowing the installer to cut precisely to the run length needed without excess waste.

Key Features

• 3/16-inch ID and 5/16-inch OD with a 1/16-inch wall thickness for consistent fit with standard push-to-connect and barb fittings
• 93 psi maximum working pressure suitable for typical shop-air and instrumentation circuits
• Polyurethane material provides abrasion resistance and sustained flexibility
• Blue color coding supports quick visual identification of pneumatic lines
• 500-foot coil with 25-foot minimum cut increments for flexible job-site usage
• Hardness rating of 85 for a balance of rigidity and bend flexibility

Compatibility

Designed for use with standard push-to-connect fittings and barb fittings sized for 3/16-inch ID and 5/16-inch OD polyurethane or polyethylene tubing in pneumatic and fluid transfer systems.

Installation Notes

Installation should be performed by a qualified pneumatic technician or maintenance mechanic. Depressurize and lock out the air supply before cutting into any existing pneumatic line. Use a sharp, square tube cutter to ensure a clean end that seats fully and seals properly in push-to-connect fittings. Do not exceed the 93 psi maximum working pressure rating, and verify all fitting connections are fully seated before restoring system pressure.
