Septic Tank Air Pump Rubber Hose Hose Clamp

This is a rubber hose and hose clamp set for a septic tank electromagnetic air pump.

I am listing it because I will not be using it.
I have inspected the items, but there may be some overlooked stains.
These are new items, but please only purchase if you understand that they have been in someone else's possession.
To keep the price reasonable, I will use recycled packaging.
I have a cat.
There is a smoker in the household, but smoking does not occur in the area where the product is stored.
Thank you for your understanding.
