105443 Nylon Push-to-connect Tubing 3/8 in Od

Product Description

The 105443 is a nylon push-to-connect tubing designed for use in pneumatic and fluid transfer systems across HVAC, plumbing, and related trade applications. With a 3/8-inch outer diameter and a 0.275-inch inner diameter, this natural-color nylon tubing provides a consistent bore for reliable flow and a secure fit in compatible push-to-connect fittings. It is rated for a temperature range of -65 to 230 degrees F at 250 psi, making it suitable for demanding service conditions. Licensed tradespeople including HVAC technicians, plumbers, and industrial service pros typically source this tubing when building or repairing pneumatic control lines, refrigerant oil drain lines, and similar low-to-medium-pressure runs.

This tubing is commonly used in residential and light commercial HVAC systems, refrigeration equipment, pneumatic control circuits, and compressed-air distribution runs. The natural nylon construction resists oils, fuels, and many common chemicals encountered in field service. Its push-to-connect compatibility makes it well-suited for quick-connect fittings used in condensate management, pneumatic thermostats, and air-line distribution systems where fast, reliable connections are required.

Key Features

• 3/8-inch OD with 0.275-inch ID for consistent flow and secure fitting engagement
• Nylon construction offers resistance to oils, fuels, and common shop chemicals
• Rated -65 to 230 degrees F at 250 psi for broad service-temperature coverage

Compatibility

Designed as an OEM-style replacement or new-installation tubing for push-to-connect pneumatic and fluid systems in HVAC, refrigeration, and light industrial service environments.

Installation Notes

Installation is typically performed by licensed HVAC technicians, plumbers, or mechanical contractors. Always depressurize and lock out the system before cutting or removing existing tubing. Use a sharp, clean tubing cutter to ensure a square, burr-free cut for a proper seal in push-to-connect fittings. Verify that all connections are fully seated and check for leaks before returning the system to service.
