Midland Industries 73352B5 Polyurethane Tubing 4mm Id 500ft

Product Description

The MIDLAND INDUSTRIES 73352B5 is a black polyurethane tubing supplied in a 500-foot coil, designed for pneumatic and fluid transfer applications in industrial and trade environments. With a 4 mm inner diameter, 6 mm outer diameter, and 1 mm wall thickness, this tubing handles a working pressure of 180 psi and carries a 28 inHg vacuum rating. A Shore A hardness of 98 provides firm structural integrity while maintaining flexibility. The 12 mm minimum bend radius allows routing in tight spaces without kinking. Licensed plumbers, pipefitters, and industrial maintenance technicians are the primary installers.

This tubing is suited for pneumatic control lines, fluid transfer, and instrumentation runs in both light industrial and commercial settings. The 500-foot coil length supports large-scale installations or extended runs without mid-line splices. Its resistance to abrasion, chemicals, cold, and heat - rated from -40 degrees F to 150 degrees F - makes it appropriate for demanding environments including outdoor routing, chemical-adjacent service, and temperature-variable mechanical rooms. It is compatible with push-to-connect fittings as well as barb-type and compression fittings, giving installers flexibility in connection method.

Key Features

• Working pressure rated to 180 psi with a 3:1 safety factor
• 28 inHg vacuum rating suitable for suction-side applications
• Shore A 98 hardness for kink and crush resistance
• 12 mm minimum bend radius enables tight-radius routing
• Temperature range of -40 degrees F to 150 degrees F
• Resistant to abrasion, chemicals, cold, heat, and kinking
• 500-foot coil minimizes splice points on long runs

Compatibility

Designed for use with push-to-connect fittings, barb-type fittings, and compression fittings as stated by the manufacturer.

Installation Notes

Installation should be performed by a qualified pipefitter, pneumatic technician, or licensed plumber depending on the application. Depressurize and isolate the system completely before cutting or connecting tubing. Use a clean, square cut with a dedicated tubing cutter to ensure leak-free seating in push-to-connect or compression fittings. Do not exceed the rated working pressure of 180 psi or the maximum service temperature of 150 degrees F.
