Parts Desk Insights

Best Use Case: Use this thru-hull connector when you need a broad-flange plastic exhaust port connection for 1-inch ID bilge plumbing hoses on hulls up to 1-1/4 inch thick.

Common Issues: For reliable sealing and installation, confirm you have the correct hose size for the 1-inch ID barb/connection and verify the hull thickness matches the 1-1/4 inch maximum. If replacing an existing fitting, inspect the surrounding area for worn/mismatched mating surfaces and ensure the hose connection is properly secured with marine-appropriate hose hardware.
