Protect Your Pressure Washer with a Reliable Thermal Relief Valve Kit

Keep your pump safe from heat buildup with the PWACCS Thermal Relief Valve Kit. When the circulating water or ambient conditions rise, the valve automatically relieves hot water to prevent damage and maintain steady performance.

The kit includes two brass thermal release valves and a roll of teflon tape, designed for quick replacement on most pressure washer pumps. Each valve measures about 1.68 inches in length and 1/2 inch in outer diameter, and the assembly is built to withstand up to 200 PSI during typical use.

What’s in the box

  • 2 x 1/4-inch NPT brass thermal relief valves
  • 1 roll of teflon tape
  • Valves: 1.68 in length, 0.5 in outer diameter
  • Maximum working pressure: 200 PSI

Why brass and why this design

Brass construction offers durability and resistance to oil, corrosion, and rust, helping the valve maintain integrity under demanding spray sessions.

Simple installation, wide compatibility

  • Standard 1/4-inch NPT threads for easy attachment to many pressure washer pumps
  • Comes with teflon tape for a leak-free connection

Brand-ready compatibility

Designed for broad compatibility with common brands and pump models, including Homelite, Briggs & Stratton, Generac, Karcher, PowerStroke, Husky, Black Max, Craftsman, Cat, Simpson, DeWalt, Ridgid, and more.

Real-world use cases and benefits

In everyday cleaning tasks, the relief valve may help safeguard the pump when heat climbs during intense sessions, or when blocking patterns cause stress. The mechanism engages around 145°F to help prevent overheating, potentially extending pump life and keeping spray consistent.

Usage tips for best results

  • Shut off the unit and relieve residual pressure before swapping valves
  • Apply equal-teflon tape coverage and avoid overtightening to prevent leaks
  • Regularly inspect valves for signs of wear and corrosion
