VEVOR Brass Clamp-Style NPT Fittings

This 12-piece set provides clamp-style female threaded connectors for 3/4 inch PEX tubing. The fittings suit water heaters, air conditioning, plumbing and hydronic heating systems. They also work in electrical conduit and RV hot or cold water distribution. Lead-free brass C46500 construction meets commercial and residential plumbing standards.

Thermals Noise and Power Draw

Solid brass bodies resist corrosion and withstand continuous temperatures up to 82°C (179.6°F). Rated working pressure reaches 100 PSI (689.5 kPa) in normal service. The material prevents wear, scratches and passivation without drawing electrical power or generating noise. Each fitting weighs approximately 0.89 kg for the full set.

Sustained Load Behaviour

Under prolonged pressure the couplings maintain seal integrity up to the rated 100 PSI limit. Brass C46500 resists creep and stress relaxation at the maximum operating temperature. Clamps remain secure during extended thermal cycling in heating or cooling loops. Reuse is possible with a pipe puller when system modifications are required.

Questions about this item

How do I install the clamp-style 3/4 NPT fittings and what step do people often miss?

Slide the clamp onto the PEX tube, push the tube fully onto the 33x34 mm brass C46500 fitting, then crimp the clamp with a calibrated tool; the step often missed is verifying the crimp gauge passes before pressurising to 100 psi.

What maintenance or replacement will the 12-piece brass clamp set need later?

The lead-free brass C46500 fittings are reusable with a pipe puller; inspect clamps for deformation after any system modification and replace only the clamp if the crimp shows gaps or the 100 psi seal is lost.

What limit appears first when the 3/4" fittings run at sustained pressure and temperature?

The 82°C / 179.6°F maximum operating temperature is the first hard limit; continuous exposure above this degrades the PEX-to-brass seal before the 100 psi pressure rating becomes critical.
