Frequently Asked Questions
What sizes of galvanized malleable cast iron reducing elbows do you offer?
We offer a wide range of reducing size combinations, from 1/2" NPT x 3/8" NPT up to 2" NPT x 1-1/2" NPT. Standard sizes are in stock, and custom combinations can be ordered for your specific marine piping needs.
Are these reducing elbows threaded or weld-end?
They are threaded with NPT threads per ASME B1.20.1, making them easy to install with standard pipe thread sealant. This is the most common requirement for shipboard piping systems.
What is the pressure rating for these fittings?
These malleable cast iron reducing elbows are rated for 300 psi WOG (water, oil, gas), which covers most marine applications. For higher pressure requirements, please contact us.
Are these elbows suitable for seawater service?
The hot-dip galvanized coating provides good corrosion resistance, making them suitable for freshwater and mild seawater exposure. For highly corrosive saltwater environments, we recommend consulting with our technical team for alternative materials such as bronze or stainless steel.
