Four Seasons 38887 A/C Orifice Tube - Front

Four Seasons Orifice Tube 38887 Overview

The Four Seasons 38887 is a standard A/C orifice tube used in expansion device service for select GM, Cadillac, Saab, and Isuzu applications. With a .062-inch orifice diameter and yellow/white color identification, it is built for vehicles that use an orifice tube style refrigerant metering setup, including many Chevrolet Trailblazer and GMC Envoy models.

Four Seasons Orifice Tube line parts are application-focused HVAC flow restrictors for service work on factory air conditioning systems. Part number 38887 is a direct-fit style replacement for vehicles that use an orifice tube in the liquid line or condenser-mounted configuration, depending on the application.

What It Helps Address

• Restricted refrigerant flow in an orifice-tube A/C system
• Incorrect metering at the liquid line or condenser-mounted restriction point
• Service replacement for a worn or contaminated expansion device
• A/C performance issues on Chevrolet Trailblazer and GMC Envoy platforms
• HVAC repair needs on Corvette, Tahoe, Yukon, Suburban, DeVille, and Seville applications

Installation Notes

Verify the vehicle’s original A/C system uses an orifice tube before installation. Match the application notes carefully, especially on Corvette and Cadillac models where the tube location is specified as condenser-mounted or mounted on the condenser half of the liquid line. This part cross-references Monroe Shocks & Struts (e.g., 182297) for the same application.
