Midland Industries 73352LU1 Polyurethane Tubing 4mm 1000 Ft

Product Description

The MIDLAND INDUSTRIES 73352LU1 is a light blue polyurethane tubing designed for pneumatic and fluid transfer applications requiring flexibility, durability, and reliable sealing. With a 4mm inner diameter, 6mm outer diameter, and 1mm wall thickness, this tubing delivers a working pressure of 180 psi and a 28 inHg vacuum rating at a 3:1 safety factor. The Shore A 98 hardness rating indicates a firm yet flexible construction that resists kinking, abrasion, and chemical exposure across a wide service temperature range of -40 to 150 degrees F. Supplied in a 1000 ft continuous coil, it is suited for routing through equipment frames and automated systems where consistent dimensions and long runs matter.

This tubing is used in pneumatic control lines, automation equipment, instrumentation, and light-duty fluid transfer systems in industrial, commercial, and mechanical service environments. The 12mm bend radius allows tight routing in confined spaces without collapsing the flow path. The light blue color provides quick visual identification on multi-line installations. Licensed HVAC technicians, industrial mechanics, and plumbing professionals working with pneumatic control systems are the primary installers of this product.

Compatibility

Designed for use with push-to-connect fittings, barb-type fittings, and compression fittings in pneumatic and fluid transfer applications.

Installation Notes

Installation should be performed by a qualified technician familiar with pneumatic tubing and fitting systems. Depressurize and de-energize the system completely before cutting or connecting tubing. Use a clean, square cut at the tubing end to ensure proper seating in push-to-connect and compression fittings. Verify that the working pressure and temperature of the application do not exceed the rated values of this tubing.
