UltraZap venturi fittings are inline plumbing fittings for ponds that draw air through a vent as water flows past, adding aeration to the system with no electrics at that point.

Fit one into the pipe run where flow is strong enough to pull air through the vent — a standard part of many pond setups, and the same principle used in aquarium and fish tank gear to mix air into water.

Good to know:
– Available sizes: 25 mm and 50 mm (moulded)
– Fits inline in pond plumbing where water flow is strong
– Draws in air to help aerate pond water
– No moving parts — works on flow alone
