Aluminum Bent Elbow 4.000 180-Degree

The Aluminum Bent Elbow 4.000 180-Degree from Woolf Aircraft Products is a critical marine plumbing and cooling system component built for serious boaters and engine builders. If you've spent years on the water maintaining inboard or outboard cooling systems, you know that a single corroded or failing elbow can compromise water circulation, spike engine temperatures, and leave you stranded far from shore. This 180-degree bend fitting routes coolant or seawater precisely where it needs to go, handling the directional changes that engine layouts demand while maintaining system integrity under load.

Constructed from lightweight 6061-T6 aluminum alloy, this bent elbow delivers the strength-to-weight ratio that aerospace and marine engineers trust. The 4.000-inch bore accepts standard marine hose or rigid tubing, and the 180-degree configuration allows you to reverse flow direction without adding bulky adapters or junction blocks. Woolf Aircraft Products engineered this fitting to resist corrosion in saltwater and freshwater environments, though periodic inspection and proper winterization remain essential maintenance. The compact 16 x 4 x 16.25-inch footprint fits tight engine compartments where space is at a premium, and at just 2.4 pounds, it won't strain your installation.

This fitting suits inboard gas and diesel engines, performance cooling upgrades, and custom marine plumbing systems where OEM elbows have failed or undersized designs restrict flow. Whether you're rebuilding a cooling loop on a cabin cruiser, upgrading a high-performance race boat, or fabricating a custom marine application, the Aluminum Bent Elbow 4.000 180-Degree pairs seamlessly with hose clamps, barbed adapters, or threaded connections depending on your system design. Install with stainless steel hardware and quality marine sealant to ensure a leak-free, long-lasting connection that keeps your engine running cool on every outing.
