Midland Industries Pilot Tubing

Overview

The MIDLAND INDUSTRIES 73233B is a Nylon 12 tubing rated for demanding fluid and air transfer applications across plumbing, pneumatic, and industrial service lines. It features a 0.275-inch inner diameter, a 3/8-inch outer diameter, and a 0.05-inch wall thickness. Working pressure is rated at 250 psi, and the temperature range spans -60 to 200 degrees F, making it suitable for both cold-climate and high-heat environments. The black nylon construction carries a Rockwell 78 R and Shore D 70 hardness rating. The coil ships in a 100-foot length, giving installers sufficient run for most routing jobs without splicing. This tubing is used in residential and light commercial applications where flexible, chemical-resistant line is required. Typical installations include pneumatic control lines, fuel transfer, hydraulic pilot lines, and general fluid conveyance in HVAC, plumbing, and refrigeration systems. The resistance profile covers abrasion, chemical exposure, and heat, making it a reliable choice for routed runs in mechanical rooms, equipment enclosures, and exposed service lines where rigid pipe is impractical.
