1/2" CTS Union Connector
A precision-fit union connector sized for 1/2" CTS (Copper Tube Size) tubing — a reliable, maintenance-friendly fitting for onboard freshwater and plumbing systems. The union design allows the line to be broken and re-joined without cutting tubing, making it a smart choice for installations where future access or servicing is anticipated.
Compatible Applications
- Freshwater supply lines and pressure water systems
- Galley plumbing and sink connections
- Head (marine toilet) water supply lines
- Livewell and baitwell fill lines using 1/2" CTS tubing
- General onboard water distribution where union disconnects are needed
Key Features
- 1/2" CTS sizing — fits standard 1/2" copper tube size tubing
- Union configuration allows disconnection without cutting lines
- Corrosion-resistant construction suited to marine environments
- Leak-free seal under normal freshwater system pressures
- Compact profile fits in tight bilge and locker plumbing runs
Parts Desk Insights
Best Use Case: This fitting is best suited for freshwater pressure system runs where the line may need to be serviced or disconnected seasonally — such as winterization access points on galley or head supply lines. The union format saves significant time versus cutting and re-flaring or re-barbing tubing during annual maintenance. If you're roughing in a new plumbing system or replacing aging push-fit connectors, this union provides a durable, accessible service point. Confirm your tubing is true 1/2" CTS before ordering — nominal 1/2" hose ID is not the same dimension.
