Dear Dan:
The Fernco Waterstop Adaptors have been used with Hobas Pipes on
many projects around the country. Our pipes have a smooth
outside wall with a constant outside diameter by size due to
centrifugally casting manufacturing process.
Your pipe being used in Coppe11, is 30" diameter with an outside
diameter of 32.0". The 32.0" is the size you would want to order
for 30" Hobas p~pe. (Note: 30" ductile iron pipe Is also 32"
O.D. so the size ~s qutte common and available).
! hope th~s addresses your question. Should you need additional
Information, please feel free to give me a call.
