T-H Marine Thru-Hull Double Nut Black 3/4" 90-Degree #TH-90-B

T-H Marine TH-90-B Thru-Hull Fittings The T-H Marine TH-90-B is a 3/4 in. 90-degree thru-hull fitting in black, built for livewell, bilge, and aeration plumbing on bass boats and aluminum fishing rigs. The 90-degree elbow design lets you route hose runs tight to the hull without kinking, which is a real advantage in cramped compartments where a straight fitting just does not have room to work. This fitting uses a double-nut design, meaning it threads from both sides of the hull panel for a more secure, rattle-free mount compared to single-nut alternatives. It is molded from UV-stabilized virgin plastic that holds its shape and color season after season without becoming brittle or cracking under sun exposure. Consistent wall thickness from the molding process means the barb seats the hose reliably every time, no guesswork on fit. T-H Marine supplies more OEM boat builders in the U.S. than any other thru-hull brand, so there is a good chance your boat already has one of their fittings somewhere in the bilge. The TH-90-B accepts standard 3/4 in. ID hoses and installs thru-hull panels up to approximately 1 in. thick. A flat-head profile on the exterior keeps the fitting low-profile and snag-free on the hull surface. Normalized SKU: TH90B UPC Code: 733572015331
