Fissure on new pump

Hi guys.

After only one week with my pump (LA PUMP) I found some fissure on it (8 at top and 4 down)

After every session one more

I pump with 5 to 7 Hg pressure for 10-15 min. Pump never fall downstairs and I wash it, after session, with warm water and gentle soap.

Have you got some notice about it?

About results.. Not to much. I’m still 4 1/4 x 4 1/4

Bye

Try to take a picture of it. The black end cap of my LA tube has always had top surface crazing cracks that I can feel, but they appear to be superficial and not structural. My tube is now several years old and the cracks have never gotten worse.
