Midland Industries 73345Y5 Polyurethane Tubing 3/8 in Od 500 Ft

Product Description

The MIDLAND INDUSTRIES 73345Y5 is a yellow polyurethane pneumatic and fluid transfer tubing rated for demanding trade and industrial applications. With a 3/8-inch outer diameter, 0.25-inch inner diameter, and a 0.063-inch wall thickness, this tubing delivers a working pressure of 150 psi and a vacuum rating of 28 inHg. It carries a 3:01 safety factor, giving installers a reliable margin in pressurized systems. The Shore A 98 hardness rating means the tubing resists abrasion and retains its shape under repeated flexing. Sold in a 500-foot coil, it is well suited for runs requiring continuous lengths without field splicing.

This tubing is designed for use with push-to-connect fittings, barb-type fittings, and compression fittings, making it compatible with standard pneumatic and fluid distribution hardware found in HVAC controls, compressed air lines, process equipment, and light industrial plumbing. The 1-inch minimum bend radius keeps the flow path unrestricted in tight routing scenarios. Its operating temperature range of -40 to 150 degrees F allows use in both refrigerated spaces and warm mechanical rooms. The yellow color aids identification in multi-line installations where tubing segregation by service is standard practice.

Key Features

• 150 psi working pressure with a 3:01 safety factor for pressurized system confidence
• 28 inHg vacuum rating supports both pressure and vacuum service
• Shore A 98 hardness provides strong resistance to abrasion, kinking, and crushing
• Compatible with push-to-connect, barb-type, and compression fittings
• Wide temperature range: -40 to 150 degrees F covers cold storage and warm mechanical environments
• 500-foot continuous coil minimizes splices in long distribution runs
• Plus or minus 0.005-inch dimensional tolerance ensures consistent fit with standard fittings

Compatibility

Designed for use with push-to-connect fittings, barb-type fittings, and compression fittings in pneumatic and fluid transfer systems. Consult fitting manufacturer specifications to confirm 3/8-inch OD tubing compatibility before installation.

Installation Notes

Depressurize and lock out any system before cutting into an existing line or replacing tubing sections. Use a sharp, square tubing cutter to ensure a clean, perpendicular cut end, which is critical for leak-free seating in push-to-connect fittings. Route tubing with smooth bends at or above the 1-inch minimum bend radius to avoid flow restriction or stress cracking at the wall. Pneumatic control tubing in commercial HVAC and refrigeration systems should comply with applicable sections of the relevant mechanical and building codes for the installation jurisdiction.
