This drain plug kit is ideal when servicing or winterizing your Raypak heater. Replacing a worn, cracked, or leaking plug helps protect your unit from freeze damage or corrosion and restores proper drainage function.

Installation Tip: Choose the plug that matches your heater’s port (plastic or brass), lubricate the O-ring lightly with pool-rated silicone grease, and hand-tighten firmly to avoid leaks without overtightening.
