UPVC Swing Check Valve

A swing check valve for sump-based reef aquariums that prevents backflow through the return line. The internal flap-style mechanism opens with minimal pressure for high flow rates, and the clear PVC body makes it easy to visually confirm open or closed position. Double union design allows quick removal for cleaning without cutting plumbing; metal-free and safe for freshwater and saltwater use.

Price: $39.99 USD
