Thaekuns 720 Series PVB Repair Kit & Bonnet Set for Zurn-Wilkins 1/2 to 2 Inch Assemblies

Revive your PVB assemblies with the Thaekuns 720 Series Repair Kit

Introducing a brand-new, unused parts kit designed to support Zurn-Wilkins 720 Series Pressure Vacuum Breaker (PVB) assemblies. The Thaekuns kit is crafted to fit a range of sizes from 1/2 inch up to 2 inches, including the Wilkins RK1-720AB 1/2" to 2" 720 Series. This is a comprehensive replacement set built to help you refresh worn components and restore smooth operation without guessing or sourcing individual parts. While not a guarantee, users often find that fresh, compatible parts can help minimize stress on aging valves and reduce the risk of leaks due to corrosion or wear.

What makes this kit practical is its completeness and attention to compatibility. The parts are designed to work together as a cohesive repair solution, so you can tackle common maintenance tasks in one go rather than chasing separate components. The set includes all the essential internal pieces you would expect for a thorough refresh, from seals to fasteners, so you can complete a repair with confidence and clarity.

What’s included and how it helps

• Bonnet washers and bonnet O-rings to help maintain a reliable seal and reduce leakage risk over time.
• Load nuts & rails, plus load washers, to promote stable alignment and even load distribution during reassembly.
• Top plates, poppet valves, and springs for coordinated, smooth valve operation after service.
• Spiders, hex nuts, and canopy screws with a canopy and bonnet assembly to complete the rebuild.
• Bonnet gasket and bonnet O-ring to seal critical joints and support long-term performance.
• Brand-new, unused parts ensure you’re working with fresh material optimized for repair tasks.

Real-life use, practical benefits

In everyday maintenance scenarios, this kit can simplify repairs by providing a full range of compatible components in one purchase. Technicians and facility staff may appreciate the clarity of a single parts set that aligns with the 720 Series design, helping reduce downtime and measurement guesswork. While situations vary, replacing worn components can improve ease of reassembly and the likelihood of a firm, dependable seal after service.

For those managing multiple PVBs in a facility, the kit’s 1/2"–2" compatibility supports a broad set of units without needing separate size-specific purchases. The parts are described as compatible with Wilkins RK1-720AB assemblies, which may simplify inventory planning and maintenance workflows. As with any repair project, assess the specific valve condition and refer to your unit’s model guide before replacing parts.
