1/2" x 3/4" PVC Male to Female Threaded Adapter

Need to connect a 3/4" fitting to a tub with 1/2" threaded ports? This PVC threaded adapter makes it easy.

With a 1/2" NPT male thread on one end and a 3/4" NPT female thread on the other, this adapter is built to bridge the gap between components like our InlineO3™ Ozone Injector and smaller threaded ports. It’s a simple, secure way to adapt your setup without leaks or guesswork.

Why it works:

• Universal NPT threads – 1/2" male x 3/4" female for clean, tight fits
• Built for compatibility – Connects directly to InlineO3™ and other 3/4" NPT fittings
• Durable Schedule 40 PVC construction – Corrosion-resistant, pressure-tolerant, and made for wet environments

Ideal for DIY builds or custom setups where sizing matters. No more wrestling with mismatched threads—just twist, tighten, and you're done.
