Weld-in Thru Hull Fitting Aluminum 1/2" ID Hose

Never worry about a loose thru-hull fitting again with our weld-in fittings. 

With these weld-in fittings, you can be confident that your Thru-hull connection will never come loose or develop a leak, providing you with the peace of mind you deserve. 

Crafted from aircraft-grade aluminum, these fittings are strong and durable enough to withstand the highest Jet Pump Pressures, ensuring your peace of mind. 

The original design was intended to weld through a .09" to .1875" thick Aluminum Transom. This allows the supply line from the outboard pump housing to penetrate the transom, providing a very rigid and safe cooling water tap.
