To measure the burst pressure of a commercially
The modified standard hydrostatic
burst procedure was used to measure the burst pressure.
This procedure used a special hose to bottle neck adaptor on
one end of the coupling, and a bottle pre-form on the other end
of the coupling. Due to the small internal volume with this
test, no water was used.
Tornado couplings tested.
Test setup with air hose/bottle neck adaptor and
pre-form on either side of the coupling.
The coupling was pressurised to 270psi
without leaks and the coupling did not show any signs of
stress. The coupling did not fail at this pressure.
Conclusions / Analysis
Though the coupling did not fail at 270psi,
it is unknown what the top burst pressure is, therefore it
would only be recommended that the coupling is not used
