Midland Industries 73343U Polyurethane Tubing 1/4 in Od 100 Ft

Product Description

The MIDLAND INDUSTRIES 73343U is a 100-foot roll of blue polyurethane pneumatic tubing designed for compressed air lines, fluid transfer, and instrumentation applications in industrial and mechanical service environments. The tubing measures 0.156 inches in inner diameter and 0.25 inches in outer diameter with a wall thickness of 0.047 inches. Rated for temperatures from -40 degrees F to 150 degrees F, this tubing is built for demanding conditions. Shore A 98 hardness provides firm, kink-resistant performance without sacrificing flexibility. HVAC technicians, plumbers, and industrial mechanics install this tubing in low-pressure pneumatic control circuits and similar applications.

This tubing is well suited for residential and light commercial control systems, pneumatic automation lines, and push-to-connect air fittings used in equipment service panels. The 100-foot roll length reduces field splicing and suits long runs in equipment rooms or across mechanical systems. The blue color coding helps technicians identify air supply lines quickly during installation and troubleshooting. Its tight bend radius of 0.476 inches allows routing through confined spaces without kinking or flow restriction.

Key Features

• 100-foot roll minimizes splices on long pneumatic runs
• Shore A 98 hardness rating delivers firm, kink-resistant flexibility
• Operating range of -40 degrees F to 150 degrees F suits both cold storage and high-heat mechanical environments
• Resistant to abrasion, chemicals, cold, heat, and kinking
• 0.476-inch minimum bend radius allows tight routing in confined spaces
• Blue color coding supports quick visual identification of air lines

Compatibility

Designed as an OEM-style replacement and general-use polyurethane tubing for pneumatic control lines, instrumentation circuits, and compressed air distribution systems using standard 1/4-inch OD push-to-connect or barb fittings.

Installation Notes

Installation is typically performed by HVAC technicians, instrumentation mechanics, or industrial pipefitters. Depressurize the pneumatic system fully before disconnecting or cutting existing tubing. Use a clean, square cut with a dedicated tubing cutter to ensure a proper seal at push-to-connect fittings. Follow applicable mechanical and pneumatic codes for pressure rating verification before putting the system back into service.
