Details:
I have a number of 45gal water barrels onto which I want to fit fluid level sight glasses. Diameter can be between 40mm and 10mm as I intend to make the device to suit what ever I can find. Length between 6oomm and 1 metre, but I would consider other lengths. Plastic must be UV light protected to ensure permanent clear vision and rigid.
Is there anyone out there that has something that would suit and that they are prepared to sell me.
Alternatively, I am open to any other suggestion or advice that can assist me.
Thanks in advance. Dave
