Midland Industries 73343G5 Polyurethane Tubing 0.25in Od 500ft

Product Description

The MIDLAND INDUSTRIES 73343G5 is a green polyurethane tubing sold in a 500-foot coil, designed for pneumatic and fluid-transfer applications where flexibility, kink resistance, and chemical durability are required. The tubing measures 0.25 inches outer diameter with a 0.156-inch inner diameter and a 0.047-inch wall thickness. It carries a working pressure rating of 180 psi and a 3:1 safety factor, making it suitable for moderate-pressure pneumatic lines. The Shore A 98 hardness rating indicates a firm yet flexible profile that holds its shape under bending loads, with a minimum bend radius of 0.476 inches. Licensed plumbers, HVAC technicians, and industrial maintenance professionals install this tubing in compressed air, pneumatic control, and light fluid-transfer systems.

This tubing is well suited for residential and commercial pneumatic control lines, instrumentation runs, and shop air distribution where a durable, long-length coil minimizes splices. The -40 to 150 degrees F operating temperature range covers most indoor and outdoor service environments, including unheated mechanical spaces and rooftop installations. A 28 inHg vacuum rating adds suitability for suction-side applications. The green color assists with line identification in multi-tube installations. Compatible with push-to-connect fittings, barb-type fittings, and compression fittings, allowing integration into a wide range of existing pneumatic assemblies without specialty tooling.

Key Features

• 500-foot coil reduces the number of field splices in long pneumatic runs
• 180 psi working pressure with a 3:1 safety factor for reliable pneumatic service
• Shore A 98 hardness provides firm, kink-resistant flexibility with a 0.476-inch minimum bend radius
• -40 to 150 degrees F operating range suits both indoor and outdoor installations
• 28 inHg vacuum rating supports suction-side and instrumentation applications
• Green color coding aids identification in multi-line pneumatic panels and control cabinets
• Dimensional tolerance of plus or minus 0.005 inches ensures consistent fit with push-to-connect and compression fittings

Compatibility

Designed for use with push-to-connect fittings, barb-type fittings, and compression fittings sized for 0.25-inch OD tubing in pneumatic and light fluid-transfer systems.

Installation Notes

Depressurize and isolate the pneumatic circuit fully before cutting or connecting tubing. Use a clean, square tubing cutter or sharp blade to ensure a flush end cut - angled cuts can cause push-to-connect fitting leaks. Follow applicable compressed air system codes and the fitting manufacturer's insertion depth requirements. Avoid routing near sharp edges or heat sources that exceed the 150 degrees F rated limit without additional protection.
