Moeller Marine Brass Elbow Fitting, Male/Male 1/4 in. NPT, Part 033438-10

The Moeller Marine Brass Elbow, part number 033438-10, is a 90-degree brass pipe fitting with male/male 1/4 in. NPT threads on both ends, letting you join two female NPT connections at a right angle. Brass construction resists corrosion in marine fuel and plumbing systems, making this elbow a reliable choice for routing fuel line, vent line, or other small-diameter plumbing runs where a straight connector will not fit the available space. Its compact, lightweight design (0.09 pounds) suits tight installations in the engine compartment, fuel tank area, or below-deck plumbing where space is limited.

Because both ends use male 1/4 in. NPT threads, this elbow is intended to connect two female NPT fittings, hose barbs, or ports that already terminate in female 1/4 in. NPT threads. It is a general-purpose plumbing fitting rather than an engine-specific replacement part, so it works across a range of boat fuel line and plumbing applications wherever a 1/4 in. NPT male/male brass elbow is needed.
