Jabsco 30653-1000 Straight Barb 3/4 Inch Port Fitting for 30600, 30700, 30710 Series Toilets

The Jabsco 30653-1000 is a straight barb port fitting sized for 3/4 inch hose, built to connect hose lines to the water inlet or discharge port on compatible Jabsco marine toilets. It is designed for use with the Jabsco 30600, 30700, and 30710 Series toilets, giving owners of these models a direct replacement fitting when a port connection is worn, cracked, or otherwise needs to be swapped out. The straight barb design allows a hose to be pushed on and secured with a standard hose clamp, forming a leak-resistant connection at the toilet's plumbing port.

This is a small, purpose-built component rather than a full assembly, which keeps repairs simple and affordable when only the port fitting itself needs attention. Because it is sized specifically to the 3/4 inch hose used in these toilet series, it helps maintain the correct fit and flow at the connection point rather than relying on an adapted or mismatched fitting.
