McDonald 5420-311 is a no-lead brass coupling designed for joining PEX, CPVC, or polyethylene tubing in residential and commercial plumbing systems. Built with an insert x insert connection configuration, this fitting accepts standard barbed fittings or push-fit adapters and creates a secure, leak-resistant joint when properly crimped or clamped. The 1-1\/2-inch fitting size handles high-volume supply lines and is well suited for potable water applications where lead-free compliance is required. Plumbers and pipefitters working on new construction or retrofit projects rely on this type of fitting for its reliable performance and straightforward installation.\u003c\/p\u003e\n\u003cp\u003eThis coupling is appropriate for residential and light commercial plumbing installations where a straight inline connection between two runs of compatible flexible tubing is needed.
