Good To Know

Q: What is the benefit of using an aluminum fitting over a plastic equivalent? A: Aluminum fittings resist cracking, high-temperature degradation, and chemical wear far better than plastic alternatives.

Q: Do I need to apply sealant to the threads during installation? A: Yes, applying thread tape or pipe sealant is highly recommended to guarantee a completely leak-free seal on the threads.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
