Raypak ProTek Shield Assembly 017960F — Sacrificial Corrosion Shield for Chlorinated & Saltwater Pools

The Raypak 017960F ProTek Shield Assembly is a compact, replaceable sacrificial shield that protects your heater’s heat exchanger from galvanic corrosion in chlorinated and saltwater pools.

Installed beneath the inlet connection on polymer headers or fitted using the ProTek Shield Adapter for brass ASME headers (adapter shipped separately for field installation), this component is engineered to intercept corrosive wear before it reaches the heat exchanger. It’s made with patent-pending design elements to provide effective, long-term protection while remaining easy to inspect and swap out during routine maintenance.

How does the ProTek Shield Assembly protect my heater?

The shield functions as a sacrificial barrier that preferentially corrodes instead of the heat exchanger’s metal surfaces. By taking the electrochemical wear itself, the ProTek Shield extends the usable life of the heat exchanger and reduces the risk of premature leaks or failures.

• Sacrificial component positioned where galvanic action is strongest
• Intercepts corrosive ions in chlorinated and saltwater pools
• Designed to be replaced before core heat exchanger damage occurs

Where and how is it installed on my Raypak heater?

On polymer-header models the shield is located under the inlet connection for straightforward access. For brass ASME-header models, the ProTek Shield ships with an adapter in the accessory carton for field installation, allowing retrofits without major plumbing changes.

• Preinstalled under inlet on polymer header units
• Adapter included for brass ASME header field installs
• Compact footprint keeps connection and flow characteristics intact

When should I replace the ProTek Shield Assembly?

The shield is designed with a simple, measurable maintenance indicator: replace it when its weight is about 40% of the original. That guideline provides a practical, objective trigger so you can plan service before the heat exchanger itself is affected.

• Visual and weight inspection recommended during routine service
• Replace at roughly 40% of original weight to avoid exchanger exposure
• Replacement is quick, minimizing downtime and labor costs

Is this shield suitable for saltwater and chlorinated pools?

Yes — the ProTek Shield Assembly is engineered specifically for aggressive pool chemistries, including both chlorinated and saltwater systems. Its materials and placement prioritize protection where corrosion is most likely, helping maintain heater performance across water treatments.

• Optimized for chlorinated pool conditions
• Compatible with saltwater pool systems where galvanic corrosion risk is higher
• Helps protect heater investment in a range of water treatment environments

Who is this for: The Raypak 017960F ProTek Shield Assembly is intended for pool owners, service technicians, and facility managers who want a proactive, low-effort way to protect Raypak heaters from galvanic corrosion. It’s especially valuable for installations exposed to saltwater or heavy chlorination, and for anyone seeking a simple maintenance schedule that prevents costly heat exchanger repairs.
