Ozone cracking & Natural rubber – Wikipedia

I HAVE NOTICED TOO MANY INCIDENTS OF RUBBER/LATEX WHATEVER CRACKING OF LATE AND AT AN INCREASE IN THE RATE IN WHICH IT IS HAPPENING… SO I INVESTIGATED

…”Form of cracking

Ozone cracks form in products under tension, but the critical strain is very small. The cracks are always oriented at right angles to the strain axis, so will form around the circumference in a rubber tube bent over. Such cracks are very dangerous when they occur in fuel pipes because the cracks will grow from the outside exposed surfaces into the bore of the pipe, so fuel leakage and fire may follow. Seals are also susceptible to attack, such as diaphragm seals in air lines. Such seals are often critical for the operation of pneumatic controls, and if a crack penetrates the seal, all functions of the system can be lost. Nitrile rubber seals are commonly used in pneumatic systems because of its oil resistance. However, if ozone gas is present, cracking will occur in the seals unless preventative measures are taken. “…

TENSION IS THE KEY WORD…

WHICH MEANS…

FIGURE IT OUT BUDS !!! – YOU HAD BETTER…

BTW – AS ABOVE SO BELOW CAVEAT APPLIES…

NEVER ONE WITHOUT THE OTHER

IN ORDER WORDS – YIN/YANG – INSIDE / OUTSIDE

IF IT IS HAPPENING ON AN EXTERIOR PROCESS…

IT IS ALSO HAPPENING ON AN INTERNAL PROCESS (BIOLOGICAL)
