Trane SSRT145 Silicone Air Tubing 0.25 Inch Id 5 Foot

Product Description

The TRANE SSRT145 is a red silicone air tubing section used in HVAC control and pneumatic circuit applications. With an inner diameter of 0.25 inches and a 5-foot length, this tubing provides a flexible, heat-resistant conduit for low-pressure air signal lines commonly found in heating and cooling equipment. Silicone construction offers broad temperature tolerance and resistance to compression set, making it well suited for both supply-air and control-air routing in confined equipment spaces. Licensed HVAC technicians install this tubing as a service replacement or during system commissioning.

This tubing is appropriate for residential and light commercial HVAC applications where a reliable, flexible air line is needed. Typical use cases include routing low-pressure pneumatic control signals, pressure sensing lines, and auxiliary air passages inside air handlers, furnaces, and rooftop units. The red color aids visual identification and differentiation from other tubing runs in multi-line installations.

Key Features

• 0.25 inch inner diameter for standard low-pressure air line connections
• 5-foot length provides sufficient run for most equipment interior routing
• Red silicone construction for easy visual identification in multi-line setups
• Silicone material offers flexibility and resistance to temperature extremes common in HVAC enclosures
• Suitable for low-pressure pneumatic signal and sensing line applications

Compatibility

Designed as an OEM-style replacement silicone air tubing for HVAC equipment requiring 0.25 inch inner diameter flexible tubing in low-pressure air circuit applications.

Installation Notes

Installation is typically performed by a licensed HVAC technician. De-energize the equipment and shut off any associated air or gas supply before replacing tubing runs. Ensure cut ends are clean and square before seating connections to barbed or compression fittings to maintain an airtight seal. Do not over-stretch or kink the tubing during routing, as this can restrict airflow in sensing or control circuits.
