About This Item
The Pentair 77707-0087 is the OEM stainless steel appliance adapter for horizontal or vertical positive pressure venting. Manufactured by Z-Flex U.S. Venting, this adapter is the factory-specified component for positive pressure vent configurations. Includes clamp ring, screws and Locktite silicone adhesive sealant for high temp usage.
⚠️ IMPORTANT: LICENSED PROFESSIONAL INSTALLATION REQUIRED
Gas and electrical heater components must be serviced by a licensed pool professional or qualified HVAC technician. Do not attempt to service gas or high-voltage components without proper certification. Venting components directly affect combustion safety — improper installation creates a risk of carbon monoxide exposure.
This adapter supports both horizontal and vertical vent runs in positive pressure venting systems. Positive pressure venting systems require components rated specifically for pressurized exhaust — standard atmospheric vent fittings are not a safe substitute. The stainless steel construction provides corrosion resistance in the hot, humid exhaust environment typical of pool heater installations.

Pro Tip
Confirm your heater is configured for positive pressure venting before ordering — this adapter is not compatible with atmospheric (natural draft) vent systems. Check the venting configuration label on your heater or consult the installation manual to verify. If your existing adapter carries a Z-Flex part number, cross-reference it against 77707-0087 before purchasing. Consult Pentair documentation for confirmed model-specific fitment.
