Quarter-turn ceramic cartridge

The Kingston Brass CD43308DX quarter-turn ceramic cartridge is a new industrial plumbing component designed to control water flow at the source. It features a 1/2 inch IPS by 3/8 inch O.D. connection and an anti-siphon design for reliable shut-off performance. The cartridge uses ceramic disc technology for smooth operation and leak-free durability.

Installers needing leak-free shut-off

This cartridge suits plumbers and maintenance teams fitting or repairing Kingston Brass shut-off valves where a quarter-turn mechanism is specified. It is not intended for installations requiring a different connection type, handle style, or valve body configuration. Buyers needing alternative thread sizes or multi-turn operation should verify compatibility before purchase.

Handles standard supply shut-off duties

The component comfortably handles on-off control for residential and light commercial supply lines connected to compatible valve bodies. It runs out of headroom when system pressure exceeds the valve body rating or when the piping layout demands a different port orientation or connection standard not matched by the 1/2 inch IPS by 3/8 inch O.D. specification.

Questions about this item

What supply line size fits the 1/2" IPS inlet on the CD43308DX valve?

Connect a standard 1/2" IPS threaded supply line to the inlet; the outlet accepts a 3/8" O.D. compression fitting for the fixture supply.

Can I keep my existing 3/8" O.D. supply tube when installing this quarter-turn valve?

Yes, the outlet is sized for 3/8" O.D. tubing, so your current supply tube can remain in place.

How do I verify the ceramic cartridge is operating correctly after installation?

Open and close the handle; water flow should start and stop instantly with no seepage past the cartridge seals.
