1/2" MPT High Limit Switch – 176°F for Hot Water Pressure Washers

1/2" MPT High Limit Switch – 176°F for Hot Water Pressure Washers

Protect your hot water pressure washer from excessive water temperatures with this 176°F High Limit Switch. Featuring a 1/2" Male NPT connection, this temperature-activated safety switch is designed to interrupt the burner control circuit when the preset temperature limit is reached.

Unlike an adjustable thermostat used to set the normal operating temperature, a high limit switch serves as an additional layer of protection against overheating.

Specifications:

• Type: High Limit Temperature Switch

• Temperature Setting: 176°F

• Connection: 1/2" Male NPT

• Application: Hot Water Pressure Washer Burner Safety Control

Applications:

• Hot water pressure washers

• Oil-fired burner systems

• Commercial cleaning equipment

• Industrial pressure washing systems

• Replacement and custom-built hot water pressure washers

Features:

• Fixed 176°F temperature setting

• 1/2" Male NPT connection

• Temperature-activated burner safety control

• Helps protect against excessive water temperatures

• Provides an additional safeguard for the heating system

• Compact design for easy installation

• Ideal for commercial hot water pressure washer applications

What it does:

The high limit switch monitors water temperature in the heating system. If the water reaches approximately 176°F, the switch changes electrical state to interrupt the burner control circuit, preventing the burner from continuing to add heat.

High Limit Switch vs. Thermostat:

The adjustable thermostat regulates the machine's normal operating temperature. The high limit switch is a safety device designed to stop burner operation when its preset temperature threshold is reached.

Why it matters:

A properly functioning high limit switch helps protect against:

• Excessive water temperatures

• Burner overheating

• Heating coil damage

• Damage to hoses, seals, and other components

• Unsafe equipment operation

Because this is a fixed 176°F switch, verify that the temperature rating and electrical configuration match your equipment before installation.

The 1/2" MPT 176°F High Limit Switch is a simple but important safety component for compatible commercial hot water pressure washer burner systems.
