Guest Equal Tee, 1/2" x 1/2" x 1/2"

The John Guest Equal Tee, 1/2" x 1/2" x 1/2", from Reliance Worldwide Corporation branches a 1/2" water line into two directions while keeping full line size on every leg. It is built for higher-flow filtration and water conditioning installations that run larger tubing and demand strong, unrestricted flow at every outlet.

With all three ports at 1/2", this tee carries robust flow on each leg, making it suitable for splitting a main supply into two full-size branches or feeding multiple components from a single line without a flow penalty. The push-fit design means you can add a branch without soldering or threading, a real advantage in larger residential and light-commercial systems where speed and clean joints matter.

Key Features

• Connection: Tube x Tube x Tube, all three ports 1/2"
• Equal union tee preserves full bore on each branch
• Polypropylene construction resists corrosion and scale
• Push-in collets grip each tube with no tools needed
• Fully demountable for flexible reconfiguration
• Reusable across multiple installs and repairs

Installation follows the familiar John Guest process. Cut each 1/2" tube square and free of burrs, then push them fully into their ports until they seat past the collets. The internal O-rings seal every connection automatically, and a firm tug confirms each grip. The corrosion-resistant polypropylene body stands up to continuous contact with treated water without scaling or rusting, so the tee performs reliably even under the steady flows these larger systems see. Should the layout need changing, depress a collet and withdraw the tube undamaged, then reconnect as required. This demountable design keeps future expansions and repairs simple. For dependable, full-flow three-way branching in water treatment plumbing, this John Guest equal tee delivers reliable, reusable performance in higher-capacity installations.

As part of the wider John Guest family, this equal tee integrates with the larger 1/2" unions, elbows, and valves that share the same collet system, letting you build a higher-capacity layout from interchangeable parts. In systems where flow is at a premium, keeping every branch at full 1/2" size ensures that adding a second outlet does not compromise the performance of the first, an important consideration for larger households.
