3/8" Thermo Valve – 190° High-Temp Brass Relief Valve

High-Temperature Thermo Relief Valve for Pressure Systems

3/8" Thermo Valve (190°) is a reliable safety component designed to prevent pump damage by releasing overheated water when system temperatures exceed 190°F. Ideal for use in pressure washers and carpet extractors, this valve ensures optimal operating temperatures and protects your equipment.

🔧 Features

• — Brass construction for durable performance in hot water systems
• — Compatible with most 3/8" pressure washer pump outlets
• — Automatically opens at 190°F to release heat
• — Compact design fits tight pump or hose configurations

✅ Advantages

• — Prevents pump seal and O-ring failure due to overheating
• — Improves equipment lifespan through heat regulation
• — Reduces downtime from thermal overloads
• — Ensures safe operating conditions during extended use

🎯 Benefits

• — Reliable thermal protection in high-heat cleaning applications
• — Efficient relief of heat buildup during pauses in spraying
• — Consistent system performance under varying loads
• — Rugged enough for daily use in restoration or industrial cleaning

🛠 How to Use

Thread the thermo valve onto the 3/8" pump outlet or fitting. Ensure a tight seal using thread tape or sealant. Valve will activate automatically at 190°F to relieve hot water buildup.

📅 When to Use

Use this valve on systems that recirculate water when idle, such as portable extractors or pressure washers, to avoid heat damage during pauses or extended use.

Protect your pump from heat stress—install a 190° Thermo Valve and clean with confidence.
