The Waterway 400-4200 union tee assembly is designed for compatible plumbing applications and includes a 1-1/2 inch union nut with a 1 inch slip by 1 inch slip tee. A part like this is useful where a serviceable union connection also needs an integrated tee branch, combining accessibility and distribution in one compact assembly.

That combination can simplify plumbing layouts that would otherwise require multiple separate fittings around a union point. This Waterway assembly is especially practical where future service access and a tee-style branch are both important to the system design.

For compatible plumbing repairs and installation work, this Waterway union tee assembly is a practical option when a removable union connection with an integrated 1 inch tee is needed.
