  • Product typeOther Appliances
  • Overall width4.92
  • Corrosion-resistant lead-free brass C46500 ensures long-lasting hygienic connections
  • 100 PSI / 82 °C rating handles hot and cold water systems
  • 50 straight couplings plus 100 clamps cover large residential or RV projects
  • Clamp-style design creates secure joints on 1/2″ PEX without special tools
  • Compact 13 × 35 mm size fits tight plumbing spaces

Pipe-to-pipe connections for PEX systems

These brass clamp fittings join 1/2 inch PEX tubing in hot and cold water, hydronic heating, air conditioning and RV distribution lines. The 50 straight couplings and 100 clamps suit residential and commercial plumbing where a reusable, lead-free joint is required.

Pressure and temperature limits

Each coupling withstands 100 psi and 82 °C or 179.6 °F, so the fittings handle typical domestic hot-water and heating circuits without deformation. Solid brass C46500 resists corrosion and scaling under continuous pressurised service.

50-piece clamp kit for 1/2 inch PEX only

The pack contains 50 straight couplings and 100 matching clamps sized exclusively for 1/2 inch PEX tube; it does not fit copper, CPVC, PPR or larger PEX diameters and includes no tools for crimp or expansion methods.

Questions about this item

How do I install the 1/2 inch clamp fittings on PEX tubing, and what step is often missed?

Cut the PEX square, slide a clamp ring onto the tube, push the brass coupling in until it seats fully, then crimp the ring with a calibrated clamp tool; the step often missed is verifying the crimp with a go/no-go gauge.

What maintenance or replacement will the brass C46500 couplings and stainless clamps need over time?

The lead-free brass resists corrosion and the clamps are single-use; plan to replace any fitting you remove with a new clamp ring and inspect for dezincification if water chemistry is aggressive.

At what pressure or temperature limit will the 100 PSI rated fittings show stress first during sustained hot-water circulation?

The 82 °C (179.6 °F) temperature ceiling is reached before the 100 PSI pressure limit in most hydronic loops, so sustained temperatures near 82 °C will degrade sealing performance first.
