When your IRC valve knob cracks, strips, or goes missing, this is the exact Lippert-sourced replacement. The 180740 is a black plastic knob designed to work directly with valve plunger assembly 240530 -- keeping your IRC system operable without hunting for a universal substitute that may not seat correctly.
The Lippert 180740 is a purpose-built replacement knob for IRC (Integrated Slide-Out or valve-based control) systems used on a wide range of Lippert-equipped RVs. It is the correct match for valve plunger assembly part number 240530 and carries Keystone RV cross-reference part number 265650, making it a common service item on Keystone-brand coaches including Cougar, Montana, Springdale, and related lines.
This is a direct drop-in part. If your existing knob is broken or missing and the underlying valve plunger assembly (240530) is intact, this knob restores full function. The valve assembly itself is sold separately -- see part 240530.
Engineered to mate with Lippert valve plunger assembly 240530. No modification or adapter needed when replacing the knob on an existing assembly.
Listed as Keystone RV part number 265650, making it easy to confirm fitment if you are sourcing via a Keystone parts reference or warranty documentation.
Molded in durable black plastic, matching the factory appearance of IRC valve controls. Resists cracking under normal operating conditions.
A common wear-and-damage item that saves a full valve assembly replacement. Weighs approximately 0.5 lbs -- easy to keep as a spare.
