90262-36 – Genuine OEM Mastercool 36″ Standard Pressure Hose Set (Blue/Yellow/Red)

Professional Overview

The 90262-36 Genuine OEM Mastercool 36″ Standard Pressure Hoses Set with Manual Shut-Off Valve Fittings (1/4″ x 1/4″ SAE) is a professional-grade component designed for refrigeration and HVAC servicing systems, including refrigerators and air conditioning units.

Manufactured by Mastercool, a trusted name in HVAC tools, this Genuine OEM hose set includes three colour-coded hoses (blue, yellow, red) used with manifold gauge systems for charging, evacuating, and diagnosing sealed refrigeration systems. Available through Appliance Kingdom with fast Canada-wide shipping, this set is widely used by appliance technicians and HVAC professionals.

If you’re experiencing refrigerant leaks, poor pressure control, or inefficient servicing performance, replacing worn or faulty hoses like this set is often a direct and reliable solution.

Function & Importance

This hose set plays a critical role in refrigeration servicing and diagnostics by connecting manifold gauges to appliance systems. Each hose serves a specific function:

• Blue (Low Pressure) – monitors suction side pressure

• Red (High Pressure) – monitors discharge pressure

• Yellow (Service Line) – used for charging, recovery, or vacuum

These hoses feature manual shut-off valve fittings, allowing technicians to control refrigerant flow precisely and prevent unnecessary release during service—improving both safety and efficiency.

Built with Grade 5 hose construction, crimped fittings, and durable brass connectors, they are designed to handle high-pressure refrigerants while maintaining leak-free operation.

Common Symptoms Indicating Replacement

If your current hoses are failing, you may notice:

• Refrigerant leaks during charging or recovery

• Difficulty maintaining system pressure

• Cracked, brittle, or worn hose material

• Inconsistent or inaccurate gauge readings

• Loss of refrigerant when disconnecting (faulty shut-off valves)

Replacing the hose set will typically restore accurate diagnostics, safe refrigerant handling, and proper system servicing performance.
