  • Brass construction resists corrosion for long-lasting repairs
  • Cinch clamps included create secure PEX connections without extra tools
  • 160 psi rating handles typical residential plumbing pressures
  • Operates from 32 to 73 degrees F for cold and hot water lines
  • Kit format provides all parts needed for a 1/2 in PEX repair

1/2 in Brass PEX Repair Kit

The Watts Radiant PCCCA3K kit supplies barbed brass couplings and cinch clamps for joining 1/2 in PEX tubing. It is intended for installers or homeowners repairing non-potable water lines in radiant heating or similar closed-loop systems.

Capacity and operating limits

Each coupling handles 1/2 in inner-diameter tubing on both ends and is rated for 160 psi at 73 °F, with a minimum service temperature of 32 °F. The brass material and standard barb profile provide reliable sealing within those pressure and temperature boundaries; the kit is not rated for higher pressures or potable-water use.

Build integration

The barbed ends slide directly onto 1/2 in PEX without specialised expansion tools, and the included cinch clamps secure the joints with a standard cinch tool. Brass construction resists corrosion in closed-loop glycol or water mixes, freeing the installer from soldering or threading while keeping the repair compact inside walls or floor cavities.

Questions about this item

Will the 1/2 in barbed brass fittings connect to my existing 1/2 in PEX tubing?

Yes, both fitting sides are barbed for 1/2 in tube inner diameter and made of brass, so they match standard 1/2 in PEX.

How can I verify the repair holds pressure after installing the cinch clamps?

Pressurise the line up to the 160 psi maximum operating pressure and check for leaks at each cinch-clamp connection.

Does the kit include the cinch tool, or only the clamps and couplings?

The kit supplies the barbed couplings and cinch clamps; a cinch tool is not included and must be purchased separately.
