Brass barbed coupling, 5/8 inch, 160 psi rating

Watts PCCCA6K Brass Barbed Coupling 5/8 in 160 psi

SKU CH-8VCZ-5XHAB

Brass barbed coupling joins 5/8 in tubing for non-potable water systems rated to 160 psi

  • Brass construction resists corrosion for long service life
  • Barbed 5/8 in ends grip tubing securely without clamps
  • Rated 160 psi for reliable non-potable water connections
  • Operates from 32 to 73 Degrees F across seasonal changes
  • Radiant PEX repair kit simplifies fixing damaged tubing runs

Brass Barbed Coupling for 5/8 in Tubing

This brass barbed coupling connects two sections of 5/8 inch inner-diameter tubing in non-potable water systems. It is built for radiant PEX repair work and carries a maximum operating pressure of 160 psi. The fitting operates between 32 and 73 degrees Fahrenheit.

Suits Radiant PEX Repair, Not Potable Lines

Installers fixing radiant heating loops or similar non-potable circuits will find the matching 5/8 inch barbs on both ends convenient. It is not certified for drinking water, so plumbers working on potable supply lines should look elsewhere. The temperature ceiling of 73 degrees Fahrenheit also rules out high-temperature hydronic applications.

Slips Into Existing Loops With Two Barbed Ends

Each end pushes into 5/8 inch PEX or compatible tubing and is secured with clamps or crimp rings supplied separately. The brass body resists corrosion in closed-loop hydronic fluid. No special tools beyond standard PEX clamping equipment are required, leaving the surrounding pipe layout unchanged.

Questions about this item

What inner-diameter tubing do I need to connect to the 5/8 in barbs on this Watts coupling?

Both barbed ends accept 5/8 in inner-diameter tubing, so have that size ready for each side of the repair.

Can I keep my existing 160 psi rated non-potable water lines when I splice in this brass coupling?

Yes — the coupling is rated for 160 psi maximum operating pressure in non-potable water applications, matching that line rating.

How do I confirm the joint is holding after I clamp the tubing onto the barbs?

Pressurise the system up to 160 psi and inspect the connection; no leaks at the barbs means the repair is working.
